Description
CROSS-REFERENCE TO RELATED APPLICATION(S)
[0001] This is a continuation application of Ser. No. 14/540,132
filed Nov. 13, 2014, which claims priority from Korean Patent
Application No. 10-2013-0150828, filed on Dec. 5, 2013, in the
Korean Intellectual Property Office, the disclosure of which is
incorporated herein in its entirety by reference.
BACKGROUND
1. Field
[0002] Apparatuses and methods consistent with exemplary
embodiments relate to a method and an apparatus for setting
operating conditions of a detector registered in an imaging system,
and more particularly, to a method and an apparatus for setting
operating conditions of a detector registered in an imaging system
based on detector information pre-stored in the detector.
2. Description of the Related Art
[0003] In general, X-rays, which are electromagnetic waves having a
wavelength of about 0.01 to about 100 .ANG., can pass through an
object. Thus, the X-rays may be commonly used in a wide range of
applications, such as medical equipment that captures images of the
inside of a living body and non-destructive testing equipment for
industrial use.
[0004] X-ray imaging apparatuses using X-rays allow X-rays emitted
by an X-ray tube (or X-ray source) to pass through an object, and
detect a difference between intensities of the passed X-rays by
using an X-ray detector to identify an internal structure of the
object. X-ray imaging apparatuses may easily identify the internal
structure of an object by using a principle that a transmission
coefficient of X-rays varies depending on a density of the object
and an atomic number of an atom included in the object. As the
wavelength of an X-ray becomes shorter, the transmission
coefficient of X-rays increases, and a picture on a screen becomes
clearer.
[0005] An X-ray imaging apparatus generally includes an X-ray
source, an X-ray detector, and an image processor. The X-ray source
irradiates an X-ray to a target under predetermined X-ray
irradiation conditions, and the X-ray detector acquires image data
based on an X-ray passed through the object and transmits the image
data to the image processor. The image processor may process the
image data to provide an image of the object to a display included
in the X-ray imaging apparatus.
[0006] In other words, when the X-ray emitted from the X-ray source
passes through the object, a scintillator included in the X-ray
imaging apparatus may change the passed X-ray to visible light
depending on a density of the object, and a photodiode included in
the X-ray imaging apparatus may change the visible light to an
electrical signal. The X-ray imaging apparatus may express a
digital image of the object through which the X-ray passes, by
using the electrical signal.

be construed as being limited to the exemplary embodiments set
forth herein; rather, these exemplary embodiments are provided such
that this disclosure will be thorough and complete, and will fully
convey the concept of the exemplary embodiments to one of ordinary
skill in the art. Also, well known functions or constructions are
not described in detail since they would obscure the exemplary
embodiments with unnecessary detail.
[0059] Hereinafter, the terms used in the specification will be
briefly described, and exemplary embodiments will be described in
detail.
[0060] The terms used in this specification are those general terms
currently widely used in the art in consideration of functions in
regard to exemplary embodiments, but the terms may vary according
to the intention of one of ordinary skill in the art, precedents,
or new technology in the art. Also, specified terms may be selected
by the applicant, and in this case, the detailed meaning thereof
will be described in the detailed description of exemplary
embodiments. Thus, the terms used in the specification should be
understood not as simple names but based on the meaning of the
terms and the overall description of exemplary embodiments.
Expressions such as "at least one of," when preceding a list of
elements, modify the entire list of elements and do not modify the
individual elements of the list.
[0061] In the present specification, the term "image" may denote
multi-dimensional data configured by discrete image elements (for
example, pixels in a two-dimensional image and voxels in a
three-dimensional image). For example, an image may include medical
images of an object acquired by an X-ray, a computed tomography
(CT), a magnetic resonance imaging (MRI), an ultrasound wave, and
other medical image systems.
[0062] Also, in the present specification, an object may include a
human being or an animal, or a part of the human being or the
animal. For example, the object may include organs, such as the
liver, the heart, the uterus, the brain, breasts, the abdomen, or
blood vessels. Also, the term "object" may include a phantom. The
phantom denotes a material having a volume, a density, and an
effective atomic number that is nearly equivalent to those of a
living organism, and a phantom according to exemplary embodiments
may be a spherical phantom having similar properties to those of

[0064] An X-ray apparatus is a medical imaging apparatus that
acquires images of internal structures of the human body by
transmitting an X-ray through the human body. The X-ray apparatus
may acquire medical images of a target object more simply within a
shorter time than other medical imaging apparatuses including an
MRI apparatus and a CT apparatus. Therefore, the X-ray system is
widely used in a simple chest photographing, abdomen photographing,
skeleton photographing, nasal sinuses photographing, neck soft
tissue photographing, and breast photographing.
[0065] FIG. 1 is a block diagram of an X-ray apparatus 100

[0068] The high voltage generator 121 generates a high voltage for
generating X-rays, and applies the high voltage to an X-ray source
122.
[0069] The X-ray irradiator 120 includes the X-ray source 122 which
receives the high voltage applied from the high voltage generator
121 to generate and irradiate the X-ray, and a collimator 123 for
guiding a path of the X-ray irradiated from the X-ray source
122.
[0070] The detector 130 detects the X-ray that is irradiated from
the X-ray irradiator 120 and transmitted through the object.
[0071] Also, the X-ray apparatus 100 may further include a
manipulator 140 including a sound outputter 141 which outputs sound
representing information relating to a photographing operation such
as the X-ray irradiation under a control of the controller 112.
[0072] The workstation 110, the X-ray irradiator 120, the high
voltage generator 121, and the detector 130 may be connected to
each other via wires or wirelessly. When they are connected to each
other wirelessly, a device (not shown) for synchronizing clocks
with each other may be further included.
[0073] The inputter 111 may include a keyboard, a mouse, a touch
screen, a voice recognizer, a fingerprint recognizer, an iris
recognizer, and the like. The user may input a command for
irradiating the X-ray via the inputter 111. For example, the
inputter 111 may include a switch for inputting the command. The
switch may be configured such that the switch needs to be
separately manipulated to input an irradiation command for
irradiating the X-ray. For example, the irradiation command for
irradiating the X-ray may be input only when the switch is pushed
twice.
[0074] That is, in an exemplary embodiment, when the user pushes
the switch, a prepare command for performing a pre-heating
operation for X-ray irradiation may be input through the switch,
and when the user pushes the switch once more, the irradiation
command for irradiating the X-ray may be substantially input
through the switch. When the user manipulates the switch as
described above, the inputter 111 generates signals corresponding
to the commands input through the switch manipulation, e.g., a
prepare signal and an irradiation signal, and outputs the generated
signals to the high voltage generator 121 generating a high voltage
for generating the X-ray.
[0075] When the high voltage generator 121 receives the prepare
signal output from the inputter 111, the high voltage generator 121
starts a pre-heating operation, and when the pre-heating is
finished, the high voltage generator 121 outputs a ready signal to
the controller 121. In addition, the detector 130 also needs to
prepare for detecting the X-ray, and thus, when the high voltage
generator 121 receives the prepare signal output from the inputter
111, the high voltage generator 121 outputs the prepare signal to
the detector 130 while performing the pre-heating operation, so
that the detector 130 may prepare for detecting the X-ray
transmitted through the object. The detector 130 prepares for
detecting the X-ray in response to the prepare signal, and when the
preparing for the detection is finished, the detector 130 outputs a
ready signal to the high voltage generator 121 and the controller
112.
[0076] When the pre-heating operation of the high voltage generator
121 is finished, the detector 130 is ready for the detecting the
X-ray, and the irradiation signal is output from the inputter 111
to the high voltage generator 121, the high voltage generator 121
generates and applies the high voltage to the X-ray source 122, and
the X-ray source 122 irradiates the X-ray.
[0077] When the irradiation signal is output from the inputter 111,
the controller 112 may output a sound output signal to the sound
outputter 141 so that the sound outputter 141 outputs predetermined
sound and the object may recognize the irradiation of X-ray. Also,
the sound outputter 141 may output sound representing other
information relating to the photographing, in addition to the X-ray
irradiation. In FIG. 1, the sound outputter 141 is included in the
manipulator 140; however, exemplary embodiments are not limited
thereto, and the sound outputter 141 may be located at a different
location from the manipulator 140. For example, the sound outputter
141 may be included in the workstation 110, or may be located on a
wall surface of an examination room in which the X-ray
photographing of the object is performed.
[0078] The controller 112 controls locations of the X-ray
irradiator 120 and the detector 130, a photographing timing, and
photographing conditions according to photographing conditions set
by the user.
[0079] In more detail, the controller 112 controls the high voltage
generator 121 and the detector 130 according to the command input
via the inputter 111 to control an irradiation timing of the X-ray,
an intensity of the X-ray, and an irradiation region of the X-ray.
Also, the controller 112 adjusts the location of the detector 130
according to a predetermined photographing condition, and controls
an operation timing of the detector 130.
[0080] In addition, the controller 112 generates a medical image of
the object by using image data transmitted from the detector 130.
In particular, the controller 121 receives the image data from the
detector 130, and generates the medical image of the object by
removing noise in the image data, and adjusting a dynamic range and
interleaving of the image data. The controller 112 may include one
or more hardware and/or software components. For example, the
controller 112 may include one or more of an integrated circuitry,
a dedicated circuit, firmware, and/or a processor such as a central
processing unit (CPU) which executes software programs stored in a
storage, e.g., a memory.
[0081] The X-ray apparatus 100 shown in FIG. 1 may further include
an outputter (not shown) for outputting the medical image generated
by the controller 112. The outputter may output information for
allowing the user to manipulate the X-ray apparatus 100, for
example, a user interface (UI), user information, or object
information. The outputter may include, for example, a printer, a
cathode ray tube (CRT) display, a liquid crystal display (LCD), a
plasma display panel (PDP), an organic light emitting diode (OLED)
display, a field emission display (FED), a light emitting diode
(LED) display, a vacuum fluorescent display (VFD), a digital light
processing (DLP) display, a primary flight display (PFD), a
three-dimensional (3D) display, a transparent display, and other
various output devices.
[0082] The workstation 110 shown in FIG. 1 may further include a
communicator (not shown) that may be connected to a server 162, a
medical apparatus 164, and a portable terminal 166 via a network
150.
[0083] The communicator may be connected to the network 150 via
wires or wirelessly to communicate with the external server 162,
the external medical apparatus 164, or the external portable
terminal 166. The communicator may transmit or receive data
relating to diagnosis of the object via the network 150, and may
transmit or receive medical images captured by the external medical
apparatus 164, for example, a CT, an MRI, or an X-ray apparatus.
Moreover, the communicator may receive a medical history or a
treatment schedule of an object (e.g., a patient) from the server
162 to diagnose a disease of the object. Also, the communicator may
perform data communication with the portable terminal 166 such as a
mobile phone, a personal digital assistant (PDA), or a laptop
computer of, for example, a doctor or a patient, as well as the
server 162 or the medical apparatus 164 in a hospital.
[0084] The communicator may include one or more elements for
communicating with external apparatuses, for example, a short
distance communication module, a wired communication module, and a
wireless communication module.
[0085] The short distance communication module may include a module
for communicating with a device located within a predetermined
distance. The short distance communication module may use short
distance communication technology including, for example, wireless
local area network (LAN), Wi-Fi, Bluetooth, Zigbee, Wi-Fi Direct
(WFD), ultra wideband (UWD), infrared data association (IrDA),
Bluetooth low energy (BLE), near field communication (NFC), or the
like; however, exemplary embodiments are not limited thereto.
[0086] The wired communication module may include a module for
communicating by using an electric signal or an optical signal, and
the wired communication module may use wired communication
technology including, for example, wired communication technology
using a pair cable, a coaxial cable, or an optical fiber cable, or
the like; however, exemplary embodiments are not limited
thereto.
[0087] The wireless communication module may transmit and/or
receive a wireless signal to/from at least one of a base station,
an external device, and a server in a mobile communication network.
Here, the wireless signal may be a voice call signal, a video call
signal, or various types of data according to transmission of text
and/or multimedia messages.
[0088] The X-ray apparatus 100 shown in FIG. 1 may include a
plurality of digital signal processors (DSPs) (not shown), an
ultra-small calculator (not shown), and a processing circuit (not
shown) for specialized usage (for example, a high speed
analog/digital (A/D) conversion, a high speed Fourier
transformation, an array process, etc.).
[0089] In addition, the communication between the workstation 110
and the X-ray generator 120, the workstation 110 and the high
voltage generator 211, and the workstation 110 and the detector 130
may use a high speed digital interface including, for example, low
voltage differential signaling (LVDS), asynchronous serial
communication such as universal asynchronous receiver transmitter
(UART), synchronous serial communication, or a low latency network
protocol such as a controller area network (CAN), and other various
communication methods.
[0090] FIG. 2 is a perspective view of a fixed type X-ray apparatus
200 according to an exemplary embodiment.
[0091] As shown in FIG. 2, the X-ray apparatus 200 includes a
manipulator 140 for providing a user with an interface for
manipulating the X-ray apparatus 200, an X-ray irradiator 120 for
irradiating the X-ray to an object, a detector 130 for detecting
the X-ray passing through the object, first through third motors
211, 212, and 213 for providing a driving power to transport the
X-ray irradiator 120, a guide rail 220, a moving carriage 230, and
a post frame 240 to transport the X-ray irradiator 120 by using the
driving power of the motors 211, 212, and 213.
[0092] The guide rail 220 includes a first guide rail 221 and a
second guide rail 222 arranged to have a predetermined angle with
respect to each other. The first guide rail 221 and the second
guide rail 222 may respectively extend in directions to
substantially cross each other.
[0093] The first guide rail 221 may be provided on a ceiling of the
examination room in which the X-ray apparatus 200 is disposed.
[0094] The second guide rail 222 may be located under the first
guide rail 221, and may be mounted to the first guide rail 221 to
slide along the first guide rail 221. A roller (not shown) that may
move along the first guide rail 221 may be provided on the first
guide rail 221. The second guide rail 222 is connected to the
roller (not shown) to move along the first guide rail 221.
[0095] A first direction D1 is defined as a direction in which the
first guide rail 221 is extended, and a second direction D2 is
defined as a direction in which the second guide rail 222 is
extended. The first direction D1 and the second direction D2 may
substantially cross each other, and may be substantially parallel
to the ceiling of the examination room.
[0096] The moving carriage 230 may be disposed under the second
guide rail 222 to move along the second guide rail 222. A roller
(not shown) moving along the second guide rail 222 may be provided
on the moving carriage 230.
[0097] Therefore, the moving carriage 230 may move in the first
direction D1 together with the second guide rail 222 along the
first guide rail 221, and may move in the second direction D2 along
the second guide rail 222.
[0098] The post frame 240 may be fixed on the moving carriage 230
and located under the moving carriage 230. The post frame 240 may
include a plurality of posts 241, 242, 243, 244, and 245.
[0099] The plurality of posts 241, 242, 243, 244, and 245 are
connected to each other while being insertable into each other.
Thus, the post frame 240 may have a length that is adjustable in an
up and down direction from the moving carriage 230.
[0100] A third direction D3 is defined as a direction in which the
length of the post frame 240 is increased or reduced. Therefore,
the third direction D3 may substantially cross the first direction
D1 and the second direction D2.
[0101] The X-ray irradiator 120 may include an X-ray source 122 for
generating the X-ray, and a collimator 123 for adjusting an
irradiation region of the X-ray that is generated and irradiated
from the X-ray source 122. The X-ray source 122 includes an X-ray
tube that may be realized as a diode including a cathode and an
anode. An inside of the X-ray tube is set as a higher vacuum state
of about 10 mmHg, and a filament of the anode is heated to a higher
temperature to generate thermal electrons. The filament may be a
tungsten filament, and a voltage of about 10 V and a current of
about 3 to 5 A may be applied to an electric wire connected to the
filament to heat the filament.
[0102] In addition, when a higher voltage of about 10 to about 300
kvp is applied between the cathode and the anode, the thermal
electrons are accelerated to crash onto a target material of the
cathode such that an X-ray is generated. The X-ray is irradiated to
outside via a window, and the window may be provided as a beryllium
thin film. Here, a portion of the energy of the electrons colliding
with the target material is consumed as heat, and a remaining
portion of the energy is converted into the X-ray.
[0103] The cathode may mainly comprise copper, and the target
material may be disposed at an opposite side to the anode. The
target material may be a higher resistive material such as, for
example, Cr, Fe, Co, Ni, W, or Mo. The target material may be
rotated by a rotating field. When the target material is rotated,
an electron impact area is increased, and a heat accumulation rate
per unit area may be increased about ten times greater than that of
a case where the target material is fixed.
[0104] The voltage applied between the cathode and the anode of the
X-ray tube is referred to as a tube voltage, and the tube voltage
is applied from the high voltage generator 121 and a magnitude of
the tube voltage may be expressed by a crest value thereof (kvp).
When the tube voltage increases, a velocity of the thermal
electrons increases, and accordingly, an energy of the X-ray
(energy of a photon) that is generated when the thermal electrons
collide with the target material is increased. A current flowing in
the X-ray tube is referred to as a tube current that may be
expressed as an average value thereof (mA). When the tube current
increases, the number of thermal electrons emitted from the
filament is increased, and accordingly, a dose of the X-ray (the
number of X-ray photons) generated when the thermal electrons
collide with the target material is increased.
[0105] Therefore, the energy of the X-ray may be adjusted according
to the tube voltage, and the intensity or dose of the X-ray may be
adjusted according to the tube current and a X-ray exposure
time.
[0106] The high voltage generator 121 may be within the X-ray
source 122; however, exemplary embodiments are not limited thereto.
For example, the high voltage generator 121 may be at another
portion of the X-ray apparatus 200.
[0107] The detector 130 may be a digital detector for detecting the
X-ray passing through the object, and may be realized as a table
type having a table 290 or a stand type having a stand 280. The
detector 130 may be provided by using a thin film transistor (TFT)
or a charge coupled device (CCD).
[0108] A rotating joint 250 may be disposed between the X-ray
irradiator 120 and the post frame 240. The rotating joint 250
allows the X-ray irradiator 120 to be coupled to the post frame
240, and supports a load applied to the X-ray irradiator 120.
[0109] The X-ray irradiator 120 connected to the rotating joint 250
may rotate on a plane that is substantially perpendicular to the
third direction D3. Here, a rotating direction of the X-ray
irradiator 120 may be defined as a fourth direction D4.
[0110] Also, the X-ray irradiator 120 may be configured to be
rotatable on a plane substantially perpendicular to the ceiling of
the examination room. Here, a rotating direction of the X-ray
irradiator 120 may be defined as a fifth direction D5. Therefore,
the X-ray irradiator 120 may rotate in the fourth direction D4 or
the fifth direction D5 based on an axis that is substantially
parallel with the first direction D1 or the second direction D2,
with respect to the rotating joint 250.
[0111] The motors 211, 212, and 213 may be provided to move the
X-ray irradiator 120 in the first through third directions D1, D2,
and D3. The motors 211, 212, and 213 may be electrically driven,
and the motors 211, 212, and 213 may respectively include an
encoder.
[0112] The motors 211, 212, and 213 may be disposed on various
locations in consideration of design convenience. For example, the
first motor 211 for moving the second guide rail 222 in the first
direction D1 may be disposed around the first guide rail 221, the
second motor 212 for moving the moving carriage 230 in the second
direction D2 may be disposed around the second guide rail 222, and
the third motor 213 for increasing or reducing the length of the
post frame 240 in the third direction D3 may be disposed in the
moving carriage 230. In another example, the first through third
motors 211, 212, and 213 may be connected to a driving power
transfer unit (not shown) to substantially linearly move the X-ray
irradiator 120 in the first through third directions D1, D2, and
D3, respectively. The driving power transfer unit may be, for
example, a belt and a pulley, a chain and a sprocket, or a
shaft.
[0113] As another example, the motors 211, 212, and 213 may be
disposed between the rotating joint 250 and the post frame 240 and
between the rotating joint 250 and the X-ray irradiator 120 to
rotate the X-ray irradiator 120 in at least one of the fourth
direction D4 and the fifth direction D5.
[0114] The manipulator 140 for providing the user with the
interface for inputting various information about X-ray
photographing and manipulating the X-ray apparatus 200 may be
disposed at, for example, a side surface of the X-ray irradiator
120.
[0115] Although FIG. 2 shows the fixed type X-ray apparatus 200
connected to the ceiling of the examination room, the X-ray
apparatus 200 of FIG. 2 is merely given as an example for
convenience of comprehension. That is, the X-ray apparatus
according to exemplary embodiments may be an X-ray apparatus having
various structures including, for example, a C-arm-type X-ray
apparatus and an angiography X-ray apparatus.
[0116] FIG. 3 is a diagram showing a configuration of a mobile
X-ray apparatus 300 capable of performing an X-ray photographing
operation substantially without limitation as to place according to
an exemplary embodiment.
[0117] The mobile X-ray apparatus 300 shown in FIG. 3 includes a
transport part 370 including a wheel for transporting the X-ray
apparatus 300, a main part 305 including an inputter 310 through
which commands for operating the X-ray apparatus 300 are input, a
high voltage generator 340 for generating a high voltage applied to
an X-ray source 355, a sound outputter 320 for outputting sound
representing information relating to a photographing operation such
as an X-ray irradiation, and a controller 330 for controlling
overall operations of the X-ray apparatus 300, an X-ray irradiator
350 including the X-ray source 355 generating the X-ray, and a
collimator 357 for guiding a path of the X-ray generated and
emitted from the X-ray source 355, and a detector 360 for detecting
the X-ray irradiated from the X-ray irradiator 350 and transmitted
through an object.
[0118] The inputter 310 receives a predetermined input from the
user. The inputter 310 may include a keyboard, a mouse, a touch
screen, a voice recognizer, a fingerprint recognizer, an iris
recognizer, and the like. The user may input a command for
irradiating the X-ray via the inputter 310, and the inputter 310
may include a switch for receiving the command input. The switch
may be configured to receive the command for irradiating the X-ray
when separately manipulated. For example, the switch may receive
the command for irradiating the X-ray only when the switch is
pushed twice.
[0119] That is, in an exemplary embodiment, when the user pushes
the switch, a prepare command for performing a pre-heating
operation for X-ray irradiation may be input through the switch,
and when the user pushes the switch once more, an irradiation
command for irradiating the X-ray may be substantially input
through the switch. When the user manipulates the switch as
described above, the inputter 310 generates signals corresponding
to the commands input through the switch manipulation, e.g., a
prepare signal and an irradiation signal, and outputs the generated
signals to the high voltage generator 340 generating a high voltage
for generating the X-ray.
[0120] When the high voltage generator 340 receives the prepare
signal output from the inputter 310, the high voltage generator 340
starts a pre-heating operation, and when the pre-heating is
finished, the high voltage generator 340 outputs a ready signal to
the controller 330. In addition, the detector 360 also needs to
prepare for detecting the X-ray, and thus, when the high voltage
generator 340 receives the prepare signal output from the inputter
310, the high voltage generator 340 outputs the prepare signal to
the detector 360 while performing the pre-heating operation, so
that the detector 360 may prepare for detecting the X-ray
transmitted through the object. The detector 360 prepares for
detecting the X-ray in response to the prepare signal, and when the
preparing for the detection is finished, the detector 360 outputs a
ready signal to the high voltage generator 340 and the controller
330.
[0121] When the pre-heating operation of the high voltage generator
340 is finished, the detector 360 is ready for the detecting the
X-ray, and the irradiation signal is output from the inputter 310
to the high voltage generator 340, the high voltage generator 340
generates and applies the high voltage to the X-ray source 355, and
the X-ray source 355 irradiates the X-ray. When the irradiation
signal is output from the inputter 310, the controller 330 may
output a sound output signal to the sound outputter 320 so that the
sound outputter 320 outputs predetermined sound and the object may
recognize the irradiation of X-ray. Also, the sound outputter 320
may output sound representing other information relating to the
photographing, in addition to the X-ray irradiation.
[0122] In FIG. 3, the sound outputter 320 is included in the main
part 305; however, exemplary embodiments are not limited thereto.
For example, the sound outputter 320 may be located separately from
the mobile X-ray apparatus 300 in a place where the mobile X-ray
apparatus 300 is located. For example, the sound outputter 320 may
be located on a wall surface of a hospital room in which the mobile
X-ray apparatus 300 is located.
[0123] The controller 330 controls locations of the X-ray
irradiator 350 and the detector 360, a photographing timing, and
photographing conditions.
[0124] In addition, the controller 330 generates a medical image of
the object by using image data transmitted from the detector 360.
In particular, the controller 330 receives the image data from the
detector 360, and generates the medical image of the object by
removing noise in the image data, and adjusting a dynamic range and
interleaving of the image data.
[0125] The main part 305 of the mobile X-ray apparatus 300 shown in
FIG. 3 may further include an outputter (not shown) for outputting
the medical image generated by the controller 330. The outputter
may output information for allowing the user to manipulate the
X-ray apparatus 300, for example, a UI, user information, or object
information.
[0126] FIG. 4 is a diagram showing a detailed configuration of an
indirect type detector 400 according to an exemplary
embodiment.
[0127] Referring to FIG. 4, the detector 400 may include a
scintillator (not shown), a photodetecting substrate 410, a bias
driver 430, a gate driver 450, and a signal processor 470.
[0128] The scintillator receives the X-ray irradiated from the
X-ray source 122 and converts the X-ray into light.
[0129] The photodetecting substrate 410 receives the light from the
scintillator and converts the light into a photodetecting voltage.
The photodetecting substrate 410 may include gate lines GL, data
lines DL, thin film transistors (TFTs) 412, photodiodes 414, and
bias lines BL.
[0130] The gate lines GL may extend in a first direction D1, and
the data lines DL may extend in a second direction D2 that
substantially crosses the first direction D1. The first direction
D1 and the second direction D2 may be substantially perpendicular
to each other. FIG. 2 shows four gate lines GL and four data lines
DL as an example.
[0131] The TFTs 412 may be arranged as a matrix in the first and
second directions D1 and D2. Each of the TFTs 412 may be
electrically connected to one of the gate lines GL and one of the
data lines DL. A gate of the TFT 412 may be electrically connected
to the gate line GL, and a source of the TFT 412 may be
electrically connected to the data line DL. In FIG. 2, sixteen
(i.e., 4.times.4) TFTs 412 are shown as an example.
[0132] The photodiodes 414 may be arranged as a matrix in the first
and second directions D1 and D2 to correspond to the TFTs 412 in a
one-to-one correspondence. Each of the photodiodes 414 may be
electrically connected to one of the TFTs 412. An N-side electrode
of each of the photodiodes 414 may be electrically connected to a
drain of each TFT 412. FIG. 2 shows sixteen (i.e., 4.times.4)
photodiodes 414 as an example.
[0133] Each of the photodiodes 414 receives the light from the
scintillator and converts the light into the photodetecting
voltage. The photodetecting voltage may correspond to an intensity
of the X-ray.
[0134] The bias lines BL are electrically connected to the
photodiodes 414. Each of the bias lines BL may be electrically
connected to a P-side electrode of each of the photodiodes 414. For
example, the bias lines BL may extend substantially parallel with
the second direction D2 to be electrically connected to the
photodiodes 414. Alternatively, the bias lines BL may extend
substantially parallel with the first direction D1 to be
electrically connected to the photodiodes 414. FIG. 2 shows four
bias lines BL which extend along the second direction D2 as an
example.
[0135] The bias driver 430 is electrically connected to the bias
lines BL to apply a driving voltage to the bias lines BL. The bias
driver 430 may selectively apply a reverse bias or a forward bias
to the photodiodes 414 through the bias lines BL. A reference
voltage may be applied to the N-side electrode of the photodiode
414. The bias driver 430 may apply a voltage that is less than the
reference voltage to the P-side electrode of the photodiode 414 to
apply a reverse bias to the photodiode 414. Alternatively, the bias
driver 430 may apply a voltage that is greater than the reference
voltage to the P-side electrode of the photodiode 414 to apply a
forward bias to the photodiode 414.
[0136] The gate driver 450 is electrically connected to the gate
lines GL to apply gate signals to the gate lines GL. The gate
driver 450 sequentially applies the gate signals to the gate lines
GL along the second direction D2. For example, when the gate
signals are applied to the gate lines GL, the gate signals may turn
on the TFTs 412. On the other hand, when the gate signals are not
applied to the gate lines GL, the gate signals may turn off the
TFTs 412.
[0137] The signal processor 470 is electrically connected to the
data lines DL to receive sample input voltages from the data lines
DL. The signal processor 470 may output image data to the outside
by using the sample input voltages. The image data may be an analog
signal or a digital signal corresponding to the photodetecting
voltage. The signal processor 470 may include one or more hardware
and/or software components. For example, the signal processor 470
may include one or more of an integrated circuitry, a dedicated
circuit, firmware, and/or a processor such as a central processing
unit (CPU) which executes software programs stored in a storage,
e.g., a memory.
[0138] Although not shown in FIG. 4, when the detector 400 shown in
FIG. 4 is a wireless detector, the detector 400 may further include
a battery and a wireless communication interface.
[0139] A wired detector is associated with a receptor (or tray) of
a stand or a table, and thus cannot be moved freely. On the other
hand, a wireless detector may be easily moved and thus may be moved
from an imaging system currently being used to another imaging
system. When a detector is moved to a new imaging system, various
information are needed to use the detector in connection with the
new imaging system. The various information need to be all stored
in the new imaging system. For example, the various information may
include an Internet Protocol (IP) address, a type, and a serial
number of the detector, and the like.
[0140] When the moved detector is not registered in the new imaging
system, the moved detector may not be immediately used, and may be
used by setting detector information on the new imaging system. In
other words, to use a detector not registered in an imaging system,
the imaging system needs to be connected to the detector via the IP
address of the detector, and the type, serial number, and
correction information of the detector need to be informed to the
imaging system and stored therein. A process of collecting the
information may be included in a process of setting operation
conditions of the detector.
[0141] According to the related art, to perform detector
information setting, a user needs to directly execute an
installation program or the like and manually set detector
information using the installation program or the like, or needs to
acquire information about a detector from another imaging system on
a network and set operation conditions of the detector based on the
acquired information.
[0142] According to an exemplary embodiment, to use a detector not
registered in an imaging system during imaging, information about
the detector may be acquired from another imaging system, or a user
may register the detector in the imaging system by using
information stored in the detector without executing a separate
installation program, and the operation conditions of the detector
may be automatically set on the imaging system.
[0143] FIG. 5 is a flowchart of a method of setting operation
conditions of a detector registered in an imaging system based on
detector information pre-stored in the detector according to an
exemplary embodiment. FIG. 6 is a flowchart of a method in which an
imaging system 1000 and a detector 2000 set operating conditions of
the detector 2000 based on detector information according to an
exemplary embodiment
[0144] Referring to FIG. 5, the method may include searching for a
detector that is to be registered (S100), acquiring detector
profile information from a found detector (S200), registering the
detector based on the acquired detector profile information (S300),
allocating a predetermined marker to represent activation or
non-activation of the registered detector (S400), transmitting
control information including the allocated marker to the detector
(S500), receiving detector correction information from the detector
(S600), and setting operating conditions of the detector based on
the received detector correction information (S700). The detector
information may include the detector profile information and the
detector correction information.
[0145] Referring to FIG. 6, the imaging system 1000 according to an
exemplary embodiment may be included in a workstation.
Alternatively, the imaging system 1000 may exist separately from
the workstation.
[0146] Operations S100 to S700 in FIG. 6 are substantially the same
or similar to those described above with respect to FIG. 5 and thus
any repetitive explanation will be omitted.
[0147] Operation S100 of searching for a detector to be registered
may include searching for a virtual IP address of the detector
2000, which is to be registered (S110) and accessing the detector
2000 via a found virtual IP address (S120).
[0148] A detector according to an exemplary embodiment may be
allocated a real IP address and a virtual IP address for each media
access control (MAC) address. A real IP address may be uniquely
allocated to each detector, and an identical virtual IP address may
be allocated to a plurality of detectors. In other words, different
real IP addresses may be allocated to different detectors, and an
identical virtual IP address may be allocated to a plurality of
detectors.
[0149] The imaging system 1000 may perform data communications with
a detector already registered on the imaging system 1000 via a real
IP address, and may determine, via a virtual IP address, whether a
detector currently not registered on the imaging system 1000
exists. The imaging system 1000 may access the to-be-registered
detector 2000 via the found virtual IP address.
[0150] After accessing the detector 2000, the imaging system 1000
may acquire detector profile information from the detector 2000.
For example, the imaging system 1000 may receive the detector
profile information from the detector 2000 via the virtual IP
address. The detector profile information may include at least one
of a real IP address, a type, and a serial number of the detector
2000.
[0151] Operation S300 of registering a detector may include storing
the detector profile information on a candidate detector list to an
available detector list on the imaging system 1000.
[0152] A predetermined marker according to an exemplary embodiment
may include at least one of a character, a number, a symbol, a
color, and an image.
[0153] Referring back to FIG. 5, a predetermined marker may be
allocated to the detector 2000 registered in the imaging system
1000 (S400). The imaging system 1000 may allocate the predetermined
marker to the registered detector 2000 so that the allocated marker
is used as an identifier of the detector 2000.
[0154] The control information including the allocated marker may
be transmitted to the detector 2000 (S500).
[0155] The imaging system 1000 may receive the detector correction
information from the detector 2000 (S600). Operation S600 of
receiving the detector correction information from the detector
2000 may include receiving the detector correction information from
the detector 2000 via an access to an activated real IP address of
the detector 2000. For example, since the detector 2000 switches
from a virtual IP address to a real IP address in response to the
control information including the allocated marker and transmits
the detector correction information to the imaging system 1000 via
the real IP address, the imaging system 1000 may receive the
detector correction information from the detector 2000.
[0156] The operating conditions of the detector 2000 may be set
based on the received detector correction information (S700).
Operation S700 of setting the operating conditions of the detector
2000 may include setting imaging conditions for performing imaging
using the detector 2000, based on the detector correction
information received from the detector 2000.
[0157] For example, the operating conditions of the detector 2000
may be referred to as an operating environment of the detector 2000
when X-ray imaging is being performed using the detector 2000, such
as, an amount of step difference correction of the detector 2000
during imaging and a range of defective pixel compensation.
[0158] In this case, the detector correction information may
include at least one of detector step difference correction
information and defective pixel compensation information. As
described above, the detector information may include the detector
profile information and the detector correction information.
[0159] FIG. 7A illustrates an image 701 of the imaging system 1000
including an available detector list 710 and a candidate detector
list 720 according to an exemplary embodiment. FIG. 7B illustrates
an image displayed on an imaging system, which includes information
on detectors according to an exemplary embodiment.
[0160] As illustrated in FIG. 7A, a display (not shown) of the
imaging system 1000 may display the image 701, which includes the
available detector list 710 and the candidate detector list
720.
[0161] The available detector list 710 includes information about
at least one detector currently registered (or identified) on the
imaging system 1000. The candidate detector list 720 includes
information about at least one detector not yet registered on the
imaging system 1000.
[0162] As described above, the detector profile information of the
to-be-registered detector acquired via the virtual IP address may
be displayed to a user in the form of the candidate detector list
720. A detector may be registered in the imaging system 1000 by
storing, in the available detector list 710, the detector profile
information of the detector displayed on the candidate detector
list 720.
[0163] In addition, a predetermined detector may be deregistered
from the imaging system 1000, based on a user input via an external
input receiver (not shown) or the like that may be connected to the
imaging system 1000. When a detector is deregistered, information
about the deregistered detector may be deleted from the available
detector list 710. The information deleted from the available
detector list 710 may be included in the candidate detector list
720, or may also be deleted from the candidate detector list
720.
[0164] As illustrated in FIGS. 7A and 7B, with respect to a
detector 2001 or 2002 registered in the imaging system 1000, real
IP address thereof may be activated. For example, the real IP
address of the detector 2001, namely, 192.168.197.80, may be
activated so that the detector 2001 may communicate with the
imaging system 1000. The real IP address of the detector 2002,
namely, 192.168.197.81, may be activated so that the detector 2002
may communicate with the imaging system 1000.
[0165] The detector 2001 or 2002 may display a registration or
non-registration status thereof in the imaging system 1000 by using
an allocated marker 2021 or 2022. For example, the allocated marker
2021 or 2022 may be displayed in a predetermined pattern via a
display of the detector 2001 or 2002. For example, the
predetermined pattern may include a pattern in which at least one
of, for example, a size, a position, and a color of the allocated
marker 2021 or 2022 is changed during a predetermined period of
time, a pattern in which the allocated marker 2021 or 2022 flickers
during a predetermined period of time, or any other patterns. When
a predetermined color, e.g., a yellow color is allocated to the
detector 2001 registered in the imaging system 1000, the detector
2001 may display the marker 2021 in the yellow color on the
display. When a predetermined color, e.g., a violet color is
allocated to the detector 2002 registered in the imaging system
1000, the detector 2002 may display the marker 2022 in the violet
color on the display. In other words, the detector 2001 or 2002
registered in the imaging system 1000 may display registration or
non-registration thereof in the imaging system 1000 by using the
allocated marker 2021 or 2022.
[0166] With respect to a detector 2003 not yet registered in the
imaging system 1000, a virtual IP address thereof may be activated.
For example, the virtual IP address of the detector 2003, namely,
192.168.197.1, may be activated so that the detector 2003 may
communicate with the imaging system 1000. In other words, the
imaging system 1000 may search for the unregistered detector 2003
by searching for the virtual IP address of the unregistered
detector 2003.
[0167] The detector 2003 not yet registered in the imaging system
1000 may not display any marker or may display a marker 2023 for
indicating non-registration of the detector 2003. For example, the
marker 2023 may comprise a marker for alarming, which may be a red
light or the like.
[0168] Referring back to FIG. 6, a method of transmitting detector
correction information of the detector 2000 to the imaging system
1000 in which the detector 2000 has been registered based on the
detector information pre-stored in the detector 2000 according to
an exemplary embodiment may include receiving an access request for
accessing the detector 2000 via the virtual IP address from the
imaging system 1000 (S1000), transmitting the detector profile
information to the imaging system 1000 (S2000), receiving first
control information including an allocated predetermined marker
from the imaging system 1000 (S3000), switching the IP address of
the detector 2000 based on the received first control information
(S4000), and transmitting the detector correction information to
the imaging system 1000 in response to a detector correction
information transmission request from the imaging system 1000
(S5000). The detector information may include the detector profile
information and the detector correction information.
[0169] The detector profile information may include at least one of
a real IP address, a type, and a serial number of the detector
2000. The predetermined marker may include at least one of a
character, a number, a symbol, a color, and an image. The detector
correction information may include at least one of detector step
difference correction information and defective pixel compensation
information.
[0170] Operation S4000 of switching the IP address of the detector
2000 based on the received first control information may include
deactivating the virtual IP address of the detector 2000 and
activating the real IP address thereof, and displaying a state
change of the detector 2000 by using the received predetermined
marker.
[0171] The method of transmitting the detector correction
information of the detector 2000 to the imaging system 1000 in
which the detector 2000 has been registered based on the detector
information pre-stored in the detector 2000 may further include
receiving second control information from the imaging system 1000
(S6000), deactivating the real IP address and activating the
virtual IP address based on the second control information (S7000),
and changing the marker to display a change of the state of the
detector (S8000).
[0172] As described above with reference to operation S500, the
imaging system 1000 may transmit the control information to the
detector 2000. The control information transmitted in operation
S500 may include the first control information and the second
control information. Alternatively, the control information
transmitted in operation S500 may include the first control
information and the control information transmitted in operation
S800 may include the second control information.
[0173] For example, the second control information may include a
command or the like for deregistering the detector 2000. In
response to the second control information transmitted at operation
S800, the detector 2000 may switch an IP address thereof (S7000).
For example, when the detector 2000 of which the real IP address
has been activated and the virtual IP address has been deactivated
receives the second control information including, for example, a
command for deregistering the detector 2000, the detector 2000 may
deactivate the real IP address and activate the virtual IP
address.
[0174] FIG. 8 is a flowchart of a method in which the imaging
system 1000 and the detector 2000 set operating conditions of the
detector 2000 based on detector information according to another
exemplary embodiment.
[0175] Referring to FIG. 8, operation S100 of searching for a
detector 2000 that is to be registered may include determining
existence or absence of detector profile information that is being
broadcast on a wired or wireless network including the imaging
system 1000 (S130) and accessing the detector 2000 that is not yet
registered and corresponds to the detector profile information that
is being broadcast on the wired or wireless network (S140).
[0176] The detector 2000 not yet registered in the imaging system
1000 may broadcast the detector profile information to different
devices (e.g., another imaging system or another detector) via the
wired or wireless network including the imaging system 1000 and the
detector 2000. On the other hand, a detector already registered in
the imaging system 1000 may perform unicast communications with the
imaging system 1000.
[0177] The imaging system 1000 may determine existence or absence
of detector profile information that is being broadcast, and
determine existence or absence of an unregistered detector
according to the determination of existence or absence of detector
profile information.
[0178] When the detector profile information being broadcast
exists, the imaging system 1000 may determine that an unregistered
detector exists on the wired or wireless network including the
imaging system 1000. On the other hand, when the detector profile
information being broadcast does not exist, the imaging system 1000
may determine that no unregistered detectors exists on the wired or
wireless network including the imaging system 1000, and may
continue the operation S100 of searching for a detector that is to
be registered.
[0179] When it is determined in operation S130 that the detector
profile information being broadcast exists, the imaging system 1000
may access the detector 200 corresponding to the broadcast detector
profile information (S140).
[0180] Operation S200 of acquiring the detector profile information
may include receiving the broadcast detector profile information
from the detector 2000 that is not yet registered (S210) and
storing the detector profile information in a candidate detector
list (S220). The detector profile information may include at least
one of a real IP address, a type, and a serial number of the
detector 2000.
[0181] Operation S300 of registering the detector 2000 may include
storing the detector profile information on the candidate detector
list to an available detector list on the imaging system 1000.
[0182] After a predetermined marker is allocated to the detector
2000 (S400) and control information including the allocated marker
is transmitted to the detector 2000 (S500), the imaging system 1000
may receive detector correction information from the detector 2000
(S600).
[0183] Operation S600 of receiving the detector correction
information from the detector 2000 may include receiving detector
correction information from the detector 2000 of which the detector
profile information has been stored in the available detector list
in the detector registration operation S300. Operation S700 of
setting the operating conditions of the detector 2000 may include
setting imaging conditions for performing imaging using the
detector 2000, based on the received detector correction
information. The detector correction information may include at
least one of detector step difference correction information and
defective pixel compensation information.
[0184] A method of transmitting the detector correction information
of the detector 2000 to the imaging system 1000 in which the
detector 2000 has been registered based on the detector information
pre-stored in the detector 2000 according to an exemplary
embodiment may include broadcasting the detector profile
information to the wired or wireless network including the imaging
system 1000 (S900), receiving first control information including
an allocated predetermined marker from the imaging system 1000
(S3000), stopping the broadcasting by the detector 2000 based on
the received first control information (S4100), and transmitting
the detector correction information to the imaging system 1000 in
response to a detector correction information transmission request
from the imaging system 1000 (S5000). The detector information may
include the detector profile information and the detector
correction information.
[0185] The method of transmitting the detector correction
information of the detector 2000 to the imaging system 1000 in
which the detector 2000 has been registered based on the detector
information pre-stored in the detector 2000 may further include
receiving an access request from the imaging system 1000 (S1000)
and transmitting the detector profile information to the imaging
system 1000 (S2000).
[0186] Operation S4100 of stopping the broadcasting by the detector
2000 based on the received first control information may include
displaying a change of the state of the detector 2000 by using the
received predetermined marker.
[0187] The method of transmitting the detector correction
information to the imaging system 1000 based on the detector
information pre-stored in the detector 2000 may further include
receiving second control information from the imaging system 1000
(S6000), starting the broadcasting of the detector profile
information to the wired or wireless network based on the received
second control information (S7100), and changing the marker to
display a change of the state of the detector 2000 (S8000).
[0188] FIG. 9 illustrates registration of a detector in an imaging
system based on detector information pre-stored in the detector
when the detector moves into another location according to an
exemplary embodiment.
[0189] For example, the second control information may be
transmitted to a detector 2003 that has been registered in and used
in the imaging system 1000 of a first imaging space 910 (or room 1)
so that the detector 2003 may be deregistered. When the detector
2003 is deregistered, the imaging system 1000 may not access the
detector 2003 via the real IP address and may only access the
detector 2003 via the virtual IP address. Due to the deregistration
of the detector 2003, the state of the detector 2003 is changed,
and thus the detector 2003 may display a predetermined marker in a
predetermined pattern. For example, on a display 2013 of the
detector 2003, a red light may flicker at time intervals of, for
example, one or two seconds to represent the deregistration of the
detector 2003.
[0190] When a user moves the detector 2003 to a second imaging
space 920 (or room 2), an imaging system 3000 of the second imaging
space 920 (or room 2) may perform operation S100 of searching for a
to-be-registered detector, to determine whether a detector to be
registered exists within the second imaging space 920. In other
words, the imaging system 3000 may search for a detector that is
accessible via a virtual IP address thereof.
[0191] The imaging system 3000 of the second imaging space 920
acquires detector profile information from a found detector,
namely, the detector 2003, and registers the found detector 2003.
When the detector 2003 is registered in the imaging system 3000 of
the second imaging space 920, the real IP address of the detector
2003 may be activated, and the virtual IP address thereof may be
deactivated. Due to the registration of the detector 2003, the
activation state of the IP address of the detector 2003 is changed,
and thus the detector 2003 may display a predetermined marker in a
predetermined pattern. For example, a blue light is turned on, on
the display 2013 of the detector 2003.
[0192] The imaging system 3000 of the second imaging space 920 may
allocate a predetermined marker to the detector 2003, transmit
control information including the allocated marker to the detector
2003, and receive detector correction information from the detector
2003.
[0193] The imaging system 3000 of the second imaging space 920 may
set operating conditions of the detector 2003 within the second
imaging space 920, based on the received detector correction
information. The set operating conditions may be stored in a
storage (not shown) included in the imaging system 3000.
Alternatively, the set operating conditions may exist separately
from the imaging system 3000 and may be stored in a storage (not
shown) connected to the imaging system 3000.
[0194] According to another example, the second control information
may be transmitted to the detector 2003 that has been registered
and used in the imaging system 1000 of the first imaging space 910
(or room 1) so that the detector 2003 may be deregistered. The
detector deregistered from the imaging system 1000 of the first
imaging space 910 may broadcast the detector profile information to
the wired or wireless network. For example, the detector 2003 may
broadcast the detector profile information to other devices
existing on the wired or wireless network, via an IP address for
broadcasting.
[0195] Due to the deregistration of the detector 2003, the state of
the detector 2003 is changed, and thus the detector 2003 may
display a predetermined marker in a predetermined pattern. For
example, on the display 2013 of the detector 2003, a red light may
flicker at time intervals of one or two seconds to represent the
deregistration of the detector 2003.
[0196] When a user moves the detector 2003 to the second imaging
space 920 (or room 2), the imaging system 3000 of the second
imaging space 920 may determine whether detector profile
information being broadcast on the wired or wireless network
exists, and may access a detector that exists on the wired or
wireless network and broadcasts the detector profile information
thereof. In other words, the imaging system 3000 of the second
imaging space 920 may perform operation S100 of searching for a
to-be-registered detector, to determine whether a detector that
broadcasts the detector profile information exists on the wired or
wireless network.
[0197] The imaging system 3000 of the second imaging space 920
acquires detector profile information from a found detector,
namely, the detector 2003, and registers the detector 2003. When
the detector 2003 is registered in the imaging system 3000 of the
second imaging space 920, the broadcasting of the detector profile
information by the detector 2003 may be stopped.
[0198] To represent the stoppage of the broadcasting by the
detector 2003, the detector 2003 may display a predetermined marker
in a predetermined pattern. For example, a blue light is turned on,
on the display 2013 of the detector 2003.
[0199] The imaging system 3000 of the second imaging space 920 may
allocate a predetermined marker to the detector 2003, transmit
control information including the allocated marker to the detector
2003, and receive detector correction information from the detector
2003.
[0200] The imaging system 3000 of the second imaging space 920 may
set operating conditions of the detector 2003 within the second
imaging space 920, based on the received detector correction
information. The set operating conditions may be stored in the
storage (not shown) included in the imaging system 3000.
Alternatively, the set operating conditions may exist separately
from the imaging system 3000 and may be stored in a storage (not
shown) connected to the imaging system 3000.
[0201] FIG. 10 is a block diagram of an imaging system 1000 for
setting operation conditions of a detector registered in the
imaging system 1000 based on detector information pre-stored in the
detector according to an exemplary embodiment.
[0202] Referring to FIG. 10, the imaging system 1000 may include a
searcher 1100 which searches for a detector that is to be
registered, a profile information acquirer 1200 which acquires
detector profile information from a found detector, a registrator
1300 which registers the detector based on the acquired detector
profile information, an allocator 1400 which allocates a
predetermined marker to represent activation or non-activation of
the registered detector, a transmitter 1500 which transmits control
information including the allocated marker to the detector, a
receiver 1600 which receives detector correction information from
the detector, and a setter 1700 which sets operating conditions of
the detector based on the received detector correction
information.
[0203] The detector information may include, for example, the
detector profile information and the detector correction
information.
[0204] The searcher 1100 may search for a virtual IP address of the
detector that is to be registered, and may access the detector that
is to be registered via a found virtual IP address.
[0205] The detector profile information may include at least one of
the real IP address of the detector, the type thereof, and the
serial number thereof, and the registrator 1300 may store the
detector profile information on a candidate detector list to an
available detector list on the imaging system 1000. The detector
profile information may be stored in a storage (not shown) included
in the imaging system 1000. Alternatively, the detector profile
information may exist separately from the imaging system 1000, but
may be stored in a storage (not shown) connected to the imaging
system 1000.
[0206] The predetermined marker may include at least one of a
character, a number, a symbol, a color, and an image.
[0207] The receiver 1600 may receive the detector correction
information from the detector by accessing an activated real IP
address of the detector. The setter 1700 may set imaging conditions
for performing imaging using the detector, based on the detector
correction information received from the detector. The detector
correction information may include at least one of detector step
difference correction information and defective pixel compensation
information.
[0208] The searcher 1100 may further include a determinator 1110
which determines whether detector profile information being
broadcast on a wired or wireless network including the imaging
system exists. The searcher 1100 may access an unregistered
detector corresponding to the detector profile information that is
being broadcast on the wired or wireless network.

information pre-stored in the detector 2000 according to an
exemplary embodiment.
[0214] Referring to FIG. 11, the detector 2000 may include a
receiver 2100 which receives an access request for accessing the
detector 2000 via a virtual IP address from the imaging system, and
a transmitter 2200 which transmits detector profile information of
the registered detector 2000 to the imaging system. The receiver
2100 may receive first control information including a
predetermined marker, from the imaging system. The detector 2000
may further include a switch 2300 which switches the IP address of
the detector 2000 based on the received first control information.
The transmitter 2200 may also transmit detector correction
information to the imaging system, in response to a detector
correction information transmission request from the imaging
system. The detector information may include the detector profile
information and the detector correction information.
[0215] The detector 2000 may further include a storage 2500 which
stores the detector profile information, the marker, or the
detector correction information.
[0216] The detector profile information may include, for example,
at least one of the real IP address of the detector 2000, the type
thereof, and the serial number thereof. The marker may include, for
example, at least one of a character, a number, a symbol, a color,
and an image. The detector correction information may include, for
example, at least one of detector step difference correction
information and defective pixel compensation information.
[0217] The switch 2300 may deactivate the virtual IP address of the
detector 2000 and activate the real IP address of the detector
2000. The detector 2000 may further include a display 2400 which
displays a change of the state of the detector 2000 by using a
received predetermined marker.
[0218] The receiver 2100 may receive second control information
from the imaging system, and the switch 2300 may deactivate the
real IP address of the detector 2000 and activate the virtual IP
address of the detector 2000, based on the received second control
