of the present disclosure. Various modifications to the disclosed
embodiments will be readily apparent to those skilled in the art,
and the general principles defined herein may be applied to other
embodiments and applications without departing from the spirit and
scope of the present disclosure. Thus, the present disclosure is
not limited to the embodiments shown, but to be accorded the widest
scope consistent with the claims.
[0024] The terminology used herein is for the purpose of describing
particular example embodiments only and is not intended to be
limiting. As used herein, the singular forms "a," "an," and "the"
may be intended to include the plural forms as well, unless the
context clearly indicates otherwise. It will be further understood
that the terms "comprise," "comprises," and/or "comprising,"
"include," "includes," and/or "including," when used in this
specification, specify the presence of stated features, integers,
steps, operations, elements, and/or components, but do not preclude
the presence or addition of one or more other features, integers,
steps, operations, elements, components, and/or groups thereof.
[0025] It will be understood that the term "system," "module,"
and/or "block" used herein are one method to distinguish different
components, elements, parts, section or assembly of different level
in ascending order. However, the terms may be displaced by other
expression if they achieve the same purpose.
[0026] Generally, the word "module," or "block," as used herein,
refers to logic embodied in hardware or firmware, or to a
collection of software instructions. A module, or a block described
herein may be implemented as software and/or hardware and may be
stored in any type of non-transitory computer-readable medium or
other storage device. In some embodiments, a software
module/unit/block may be compiled and linked into an executable
program. It will be appreciated that software modules can be
callable from other modules/units/blocks or from themselves, and/or
may be invoked in response to detected events or interrupts.
Software modules/units/blocks configured for execution on computing
devices (e.g., the processor 210 as illustrated in FIG. 2) may be
provided on a computer-readable medium, such as a compact disc, a
digital video disc, a flash drive, a magnetic disc, or any other
tangible medium, or as a digital download (and can be originally
stored in a compressed or installable format that needs
installation, decompression, or decryption prior to execution).
Such software code may be stored, partially or fully, on a storage
device of the executing computing device, for execution by the
computing device. Software instructions may be embedded in a

described herein may be implemented as software
modules/units/blocks, but may be represented in hardware or
firmware. In general, the modules/units/blocks described herein
refer to logical modules/units/blocks that may be combined with
other modules/units/blocks or divided into
sub-modules/sub-units/sub-blocks despite their physical
organization or storage. The description may be applicable to a
system, an engine, or a portion thereof.
[0027] It will be understood that when a module or block is
referred to as being "connected to," or "coupled to," another
module, or block, it may be directly connected or coupled to, or
communicate with the other module, or block, or an intervening
unit, engine, module, or block may be present, unless the context
clearly indicates otherwise. As used herein, the term "and/or"
includes any and all combinations of one or more of the associated
listed items.
[0028] These and other features, and characteristics of the present
disclosure, as well as the methods of operation and functions of
the related elements of structure and the combination of parts and
economies of manufacture, may become more apparent upon
consideration of the following description with reference to the
accompanying drawings, all of which form a part of this disclosure.
It is to be expressly understood, however, that the drawings are
for the purpose of illustration and description only and are not
intended to limit the scope of the present disclosure. It is
understood that the drawings are not to scale.
[0029] An aspect of the present disclosure relates to systems and
methods for configuring a medical device before a scan is performed
on a patient. A processing device (e.g., a console) may determine
the environment of a scanning room in real time, for example,
whether a patient has entered the scanning room, and start to
adjust the medical device from a standby mode to a work mode when
it is determined that a patient has entered the scanning room.
Alternatively or additionally, the processing device may initialize
a gantry angle of the medical device, and then adjust the
initialized gantry angle to a pre-set gantry angle that is used in
a scan to be performed on a target object.

system 100 via the network 120.
[0048] To implement various modules, units, and their
functionalities described in the present disclosure, computer
hardware platforms may be used as the hardware platform(s) for one
or more of the elements described herein. A computer with user
interface elements may be used to implement a personal computer
(PC) or any other type of work station or terminal device. A
computer may also act as a server if appropriately programmed.
[0049] It should be noted that the above description is merely
provided for the purposes of illustration, and not intended to
limit the scope of the present disclosure. For persons having
ordinary skills in the art, multiple variations and modifications
may be made under the teachings of the present disclosure. However,
those variations and modifications do not depart from the scope of
the present disclosure.
[0050] FIG. 4 is a block diagram illustrating an exemplary
processing device according to some embodiments of the present
disclosure. The processing device 140 may include an angle
determination module 410 and/or a mode adjustment module 420.
[0051] The angle determination module 410 may be configured to
initialize a gantry angle of the medical device 110 and adjust the
initialized gantry angle to a pre-set gantry angle that is used in
a scan to be performed on a target object. The angle determination
module 410 may include an angle acquisition unit 412, an angle
initialization unit 414, and an angle adjustment unit 416.
[0052] The angle acquisition unit 412 may be configured to acquire
one or more prior gantry angle values of a medical device (e.g.,
the medical device 110). For example, for a CT scanner, an X-ray
source of the CT scanner may rotate together with a gantry of the
CT scanner. A gantry angle value may indicate a location of the
X-ray source. For example, if the X-ray source is rotated to a
location corresponding to 3 o'clock, the gantry angle value is
90.degree.. As another example, if the X-ray source is rotated to a
location corresponding to 9 o'clock, the gantry angle value is
270.degree..
[0053] In some embodiments, a prior gantry angle value may refer to
a gantry angle value that was used in a previous scan prior to the
current time. For example, the angle determination module 410 may
acquire prior gantry angle values used in the past 30 days. In some
embodiments, the one or more prior gantry angle values may
correspond to a same medical device.
[0054] The angle initialization unit 414 may be configured to
initialize a gantry angle of the medical device (e.g., the medical
device 110) to Degree 0 (e.g., a gantry angle) based on the one or
more prior gantry angle values. In some embodiments, Degree 0 was
mostly frequently used during a certain period (e.g., past 30 days
from the current time) among the one or more prior gantry angle
values. In some embodiments, initializing the gantry angle of the
medical device using Degree 0 may reduce the time of adjusting the
X-ray source to a gantry angle for a scan to be performed on the
target object. Description regarding the determination of a gantry
angle value of Degree 0 may be found elsewhere in the present
disclosure. See, e.g., FIG. 7, and the description thereof.
[0055] The angle adjustment unit 416 may be configured to acquire a
pre-set gantry angle Degree 1. In some embodiments, the pre-set
gantry angle may be used to a scan to be performed on the target
object. The angle determination module 410 may acquire the pre-set
gantry angle based on a scan protocol.
[0056] The angle adjustment unit 416 may also be configured to
determine whether Degree 0 is equal to Degree 1. The angle
adjustment unit 416 may adjust the gantry angle from Degree 0 to
Degree 1 in response to a determination that Degree 0 is not equal
to Degree 1. The angle adjustment unit 416 may keep the gantry
angle at Degree 0 in response to a determination that Degree 0 is
equal to Degree 1.
[0057] The mode adjustment module 420 may be configured to adjust
the medical device 110 from a standby mode to a work mode. The mode
adjustment module 420 may include an information acquisition unit
422, an analysis unit 424, and a component adjustment unit 426.
[0058] The information acquisition unit 422 may be configured to
acquire information relating to a target object. The information
relating to the target object may include environment information,
personal information, registration information, medical record
information, a scan protocol, or the like, or a combination thereof
of the patient. The environment information may indicate whether
there is a person in a certain region (e.g., a scanning room, a
registration office, a space above a scanning table of the medical
device 110). The personal information of a target object may
include the name, the age, the gender, the home address, the phone
number, the occupation, the work unit, the date of birth, or the
like, or any combination thereof. The registration information of a
target object may include an item related to the medical device 110
(e.g., a CT scan of brain, an MRI scan of chest), the payment
amount associated with the item, the payment method (e.g., cash
payment, mobile payment, bank transfer, credit card payment, debit
card payment) associated with the item, an appointment time for the
item, or the like, or any combination thereof. The medical record
may be a systematic documentation of a patient's medical history
and include drugs and therapies for the patient.
[0059] The scan protocol may be designed with respect to one or
more tissues to be imaged, diseases to be diagnosed, and/or
clinical scenarios. The scan protocol may include one or more
parameters associated with the scan of the target object. The scan
protocols for different medical devices or different target objects
may be different. For example, for an MRI scan, the scan protocol
may include a certain number of pulse sequences. The pulse
sequences may include spin echo sequences, gradient echo sequences,
diffusion sequences, inversion recovery sequences, or the like, or
any combination thereof. For instance, the spin echo sequences may
include fast spin echo (FSE), turbo spin echo (TSE), rapid
acquisition with relaxation enhancement (RARE), half-Fourier
acquisition single-shot turbo spin-echo (HASTE), turbo gradient
spin echo (TGSE), or the like, or any combination thereof. For an
MRI scan, the scan protocol may also include image contrast and/or
ratio, a region of interest (ROI), slice thickness, an imaging type
(e.g., T1 weighted imaging, T2 weighted imaging, proton density
weighted imaging, etc.), a spin echo type (spin echo, fast spin
echo (FSE), fast recovery FSE, single shot FSE, gradient recalled
echo, fast imaging with stead-state procession, and so on), a flip
angle value, acquisition time (TA), echo time (TE), repetition time
(TR), echo train length (ETL), the number of phases, the number of
excitations (NEX), inversion time, bandwidth (e.g., radiofrequency
(RF) receiver bandwidth, RF transmitter bandwidth, etc.), or the
like, or any combination thereof. As another example, for a CT
scan, the scan protocol may include a gantry angle, a radiation
dose of X-rays emitted from an X-ray source, a scan period, a
gantry location, a rotation speed of the gantry, the number of
times the gantry rotates, or the like, or any combination
thereof.
[0060] In some embodiments, the mode adjustment module 420 may
acquire the information relating to the target object through at
least one of one or more sensors, one or more remote information
devices, one or more human machine interaction devices, and
software implemented by the processing device 140.
[0061] The analysis unit 424 may be configured to make a
determination by analyzing information related to the scan to be
performed on a target object. In some embodiments, the analysis
unit 424 may determine whether there is a scan to be performed on
the target object by analyzing the information relating to the
target object. In some embodiments, the analysis unit 424 may
determine whether the medical device 110 has completed the scan
performed on the target object. In some embodiments, the analysis
unit 424 may determine whether the medical device 110 satisfies a
condition to get into a standby mode.
[0062] The component adjustment unit 426 may be configured to
adjust the medical device 110 between the standby mode and the work
mode. In some embodiments, the component adjustment unit 426 may
adjust the medical device 110 from the standby mode to the work
mode to perform the scan on the target object based on the scan
protocol in response to a determination that there is a scan to be
performed on the target object. In some embodiments, after the
medical device 110 has completed the scan performed on the target
object, the component adjustment unit 426 may adjust the medical
device 110 to the standby mode in response to a determination that
the medical device satisfies a condition to get into the standby
mode.
[0063] The modules and/or units in the processing engine 140 may be
connected to or communicate with each other via a wired connection
or a wireless connection. The wired connection may include a metal
cable, an optical cable, a hybrid cable, or the like, or any
combination thereof. The wireless connection may include a Local
Area Network (LAN), a Wide Area Network (WAN), a Bluetooth, a
ZigBee, a Near Field Communication (NFC), or the like, or any
combination thereof. Two or more of the modules (or units) may be
combined as a single module (or unit), and any one of the modules
(or units) may be divided into two or more units (or blocks). For
example, the angle determination module 410 may be integrated in
the mode adjustment module 420 as a single module which may adjust
the gantry angle and adjust the medical device 110 between a
standby mode and a work mode. As another example, the information
acquisition unit 422 may include four individual blocks that can be
implemented as separate units. The first block may be configured to
acquire the information relating to the target object through one
or more sensors. The second block may be configured to acquire the
information relating to the target object through one or more
remote information devices. The third block may be configured to
acquire the information relating to the target object through one
or more human machine interaction devices. The fourth block may be
configured to acquire the information relating to the target object
through one or more software implemented by the processing device
140.
[0064] It should be noted that the above description is merely
provided for the purposes of illustration, and not intended to
limit the scope of the present disclosure. For persons having
ordinary skills in the art, multiple variations and modifications
may be made under the teachings of the present disclosure. However,
those variations and modifications do not depart from the scope of
the present disclosure. For example, the processing device 140 may
further include a storage module (not shown in FIG. 4). The storage
module may be configured to store data generated during any process
performed by any component of in the processing device 140. As
another example, each of components of the processing device 140
may include a storage apparatus. Additionally or alternatively, the
components of the processing device 140 may share a common storage
apparatus. As still another example, the angle determination module
410 or the mode adjustment module 420 may be omitted.
[0065] FIG. 5 is a flowchart illustrating an exemplary process for
adjusting a medical device according to some embodiments of the
present disclosure. The process 500 may be implemented in the
adjustment system 100 illustrated in FIG. 1. For example, the
process 500 may be stored in the storage device 150 and/or the
storage 220 in the form of instructions (e.g., an application), and
invoked and/or executed by the processing device 140 (e.g., the
processor 210 illustrated in FIG. 2, or one or more modules in the
processing device 140 illustrated in FIG. 4). The operations of the
illustrated process presented below are intended to be
illustrative. In some embodiments, the process 500 may be
accomplished with one or more additional operations not described,
and/or without one or more of the operations discussed.
Additionally, the order in which the operations of the process 500
as illustrated in FIG. 5 and described below is not intended to be
limiting.
[0066] In 510, the mode adjustment module 420 (e.g., the
information acquisition unit 422) may acquire information relating
to a target object. The information relating to the target object
may include environment information, personal information,
registration information, medical record information, a scan
protocol, or the like, or a combination thereof of the patient. The
environment information may indicate whether there is a person in a
certain region (e.g., a scanning room, a registration office, a
space above the scanning table of the medical device 110). The
personal information of a target object may include the name, the
age, the gender, the home address, the phone number, the
occupation, the work unit, the date of birth, or the like, or any
combination thereof. The registration information of a target
object may include an item related to a medical procedure, the
payment amount associated with the item, the payment method (e.g.,
cash payment, mobile payment, bank transfer, credit card payment,
debit card payment) associated with the item, an appointment time
for the item, or the like, or any combination thereof. The medical
record may be a systematic documentation of a patient's medical
history and include drugs and therapies for the patient.
[0067] The scan protocol may be designed with respect to one or
more tissues to be imaged, diseases to be diagnosed, and/or
clinical scenarios. The scan protocol may include one or more
parameters associated with the scan of the target object. For
example, the scan protocol may include a type of the medical device
used in the scan, a region of interest (ROI) of the target object,
the duration of the scan, the size of a reconstruction image, the
resolution of a reconstruction image, or the like, or any
combination thereof. The scan protocols for different medical
devices or different target objects may be different. For example,
for an MRI scan, the scan protocol may include a certain number of
pulse sequences. The pulse sequences may include spin echo
sequences, gradient echo sequences, diffusion sequences, inversion
recovery sequences, or the like, or any combination thereof. For
instance, the spin echo sequences may include fast spin echo (FSE),
turbo spin echo (TSE), rapid acquisition with relaxation
enhancement (RARE), half-Fourier acquisition single-shot turbo
spin-echo (HASTE), turbo gradient spin echo (TGSE), or the like, or
any combination thereof. For an MRI scan, the scan protocol may
also include image contrast and/or ratio, a region of interest
(ROI), slice thickness, an imaging type (e.g., T1 weighted imaging,
T2 weighted imaging, proton density weighted imaging, etc.), a spin
echo type (spin echo, fast spin echo (FSE), fast recovery FSE,
single shot FSE, gradient recalled echo, fast imaging with
stead-state procession, and so on), a flip angle value, acquisition
time (TA), echo time (TE), repetition time (TR), echo train length
(ETL), the number of phases, the number of excitations (NEX),
inversion time, bandwidth (e.g., radiofrequency (RF) receiver

protocol may include a gantry angle, a rotation speed of a gantry,
a radiation dose of X-rays emitted from an X-ray source, one or
more slices of the target object to be scanned, or the like, or any
combination thereof.
[0068] In some embodiments, the mode adjustment module 420 may
acquire the information relating to the target object through at
least one of one or more sensors, one or more remote information
devices, one or more human machine interaction devices, and
software implemented by the processing device 140.
[0069] In some embodiments, the mode adjustment module 420 may
acquire the environment information through one or more sensors.
The sensor may include an infrared sensor, a pressure sensor, a
microwave sensor, a temperature sensor, a light sensitive sensor, a
heat sensitive sensor, an image sensor (e.g., a camera), or the
like, or a combination thereof.
[0070] In some embodiments, one or more infrared sensors may be
mounted somewhere in a hospital, such as a scanning room, a
registration office, etc. The infrared sensor may acquire infrared
signals and/or infrared images within a certain region (e.g., a
scanning room, a registration office) constantly and send the
acquired infrared signals and/or infrared images to the mode
adjustment module 420 in real time or at intervals (e.g., every 2
minutes).
[0071] In some embodiments, one or more pressure sensors may be
mounted on a scanning table of the medical device 110. The pressure
sensor may acquire pressure signals within a certain region (e.g.,
the scanning table) by, for example, one or more elastic components
in the pressure sensor. For example, when a patient lies on the
scanning table, one or more pressure sensors mounted on the
scanning table may generate pressure signals based on the
deformation of the one or more elastic components, and transmit the
pressure signals to the mode adjustment module 420.
[0072] In some embodiments, one or more temperature sensors may be
mounted somewhere in a hospital, such as a scanning room, a
registration office, a scanning table, etc. The temperature sensor
may acquire a temperature within a certain region (e.g., a scanning
room, a registration office) in real time and send the temperature
to the mode adjustment module 420 in real time or at intervals
(e.g., every 2 minutes). The temperature sensor may include a
contact temperature sensor, a non-contact temperature sensor, or
the like, or any combination thereof.
[0073] In some embodiments, one or more image sensors (e.g.,
cameras) may be mounted somewhere in a hospital, such as a scanning
room, a registration office, a scanning table, etc. The image
sensor may acquire two-dimensional (2D) images or three-dimensional
(3D) images within a certain region (e.g., a scanning room, a
registration office) in real time and send the acquired images to
the mode adjustment module 420 in real time or at intervals (e.g.,
every 2 minutes).
[0074] In some embodiments, the mode adjustment module 420 may
acquire the personal information, the registration information, or
the medical record information from one or more remote information
devices. The remote information device may include an electronic
system, such as a Hospital Information System (HIS), a Radiology
Information System (RIS), a Laboratory Information System (LIS), an
Electronic Medical Record (EMR), a Picture Archiving and
Communication System (PACS), or the like, or a combination thereof.
The HIS may include a finance management system, a personnel
management system, a hospital management system, an outpatient
management system, a drug management system, or the like, or a
combination thereof.
[0075] In some embodiments, the mode adjustment module 420 may
acquire the information (e.g., the personal information, the
registration information, or the medical record information)
relating to the target object from one or more human machine
interaction devices. In some embodiments, the processing device 140
and a user (e.g., a patient, a doctor, an imaging engineer) may
exchange information through the human machine interaction device.
For example, the user may download a medical record of a patient
through the human machine interaction device. As another example,
the human machine interaction device may display a medical image
(e.g., an MRI image) to the user though the human machine
interaction device. As still another example, the user may input an
instruction to control the medical device 110 through the human
machine interaction device. The human machine interaction device
may include an I/O device, such as a keyboard, a mouse, a display
screen, a touch screen, or the like, or any combination thereof.
The human machine interaction device may be implemented in the
processing device 140 (e.g., the I/O 230), the terminal 130 (e.g.,
the I/O 350), or the external device 160 communicated with the
processing device 140. In some embodiments, the user may input the
scan protocol through the human machine interaction device. The
human machine interaction device may acquire the scan protocol
based on the use's input. In some embodiments, the human machine
interaction device may include a human machine interface (HMI).
[0076] In some embodiments, the mode adjustment module 420 may
acquire the information (e.g., the personal information, the
registration information, or the medical record information)
relating to the target object through software (e.g., image
configuration software, interface configuration software) installed
in the processing device 140 and/or the remote information device.
When the user input the information (e.g., the personal
information, the registration information, the medical record
information, the scan protocol) relating to the target object
through the software, the software may send the user' input to the
mode adjustment module 420 in real time.
[0077] In 520, the mode adjustment module 420 (e.g., the analysis
unit 424) may determine whether there is a scan to be performed on
the target object by analyzing the information relating to the
target object. The process 500 may proceed to 530 in response to a
determination that there is a scan to be performed on the target
object. The process 500 may proceed to 560 in response to a
determination that there is no scan to be performed on the target
object.
[0078] Merely by way of example, the mode adjustment module 420 may
determine whether a patient has entered the scanning room by
analyzing infrared signals received from one or more infrared
sensors mounted in the scanning room.
[0079] Merely by way of example, the mode adjustment module 420 may
determine whether a patient has lain on the scanning table by
analyzing pressure signals received from one or more pressure
sensors mounted on the scanning table. In some embodiments, the
pressure sensor may acquire pressure signals based on the
deformation of one or more elastic components in the pressure
sensor. The larger the deformation is, the stronger the strength of
the pressure signals may be. The mode adjustment module 420 may
determine that a patient has lain on the scanning table in response
to a determination that the strength of the pressure signals
received from the one or more pressure sensors mounted on the
scanning table is greater than a strength threshold.
[0080] Merely by way of example, the mode adjustment module 420 may
determine whether a patient has lain on the scanning table or has
entered the scanning room by analyzing the temperature received
from one or more temperature sensors mounted on the scanning table
or in the scanning room. In some embodiments, the more the people
there are in a certain region, the higher the temperature related
to the certain region may be. The mode adjustment module 420 may
determine that there is a patient in a certain region (e.g., the
scanning room or the scanning table) in response to a determination
that a difference between the current temperature and a prior
temperature detected in the past (e.g., 5 minutes before the
current time) is greater than a threshold temperature (e.g.,
2.degree. C.).
[0081] Merely by way of example, the mode adjustment module 420 may
determine whether a patient has lain on the scanning table or has
entered the scanning room by analyzing images received from one or
more image sensors (e.g., cameras) mounted on the scanning table or
in the scanning room.
[0082] In some embodiments, the mode adjustment module 420 may
determine whether there is at least one scan relating to the
medical device 110 (e.g., a CT scan, an MRI scan) in the items that
have been registered. The mode adjustment module 420 may determine
an interval between an appointment time of each scan and the
current time in response to a determination that there is at least
one scan relating to the medical device 110 in the items that have
been registered, and determine whether there is at least one
interval that is less than a threshold time (e.g., 30 minutes). The
mode adjustment module 420 may determine that there is a scan to be
performed on the target object in response to at least one of a
determination that there is at least one interval that is less than
the threshold time, a determination that a patient has entered the
scanning room, and a determination that a patient has lain on the
scanning table.
[0083] In 530, the mode adjustment module 420 (e.g., the
information acquisition unit 422) may obtain a scan protocol based
on the information relating to the target object. For example, the
mode adjustment module 420 may obtain the scan protocol based on a
scan related to the medical device 110 of which the appointment
time is closest to the current time.
[0084] In some embodiments, the scan protocol relating to the
target object may be determined in advance and be stored in a
storage medium (e.g., the storage device 150, the storage 220). The
mode adjustment module 420 may obtain the scan protocol relating to
the target object from the storage medium. In some embodiments, a
user may input, through the human machine interaction device, the
scan protocol relating to the target object after a determination
that there is a scan to be performed on the target object based on
the information relating to the target object. The mode adjustment
module 420 may obtain the scan protocol from the human machine
interaction device based on the input of the user.
[0085] In 540, the mode adjustment module 420 (e.g., the component
adjustment unit 426) may adjust a medical device (e.g., the medical
device 110) from a standby mode to a work mode to perform the scan
on the target object based on the scan protocol. In some
embodiments, the mode adjustment module 420 may adjust the
components of the medical device 110 in the standby mode, adjust
reconstruction parameters (e.g., the size of a reconstruction
image, the number of the detectors of the medical device 110, the
resolution of a reconstruction image), or the like, or any
combination thereof. For example, for a CT scanner, the mode
adjustment module 420 may correct an X-ray source, correct a
detector, correct the position of a scanning table, preheat a
high-voltage generator, or adjust a gantry angle. In some
embodiments, the standby mode may indicate that the medical device
110 is kept on but is not performing a medical procedure (e.g., a
scan procedure to a target object).
[0086] In some embodiments, the processing device 140 may
communicate with one or more medical devices, such as a CT scanner,
an MRI scanner, an X-ray scanner, and a PET scanner, etc. The mode
adjustment module 420 may adjust one of the one or more medical
devices communicating with the processing device 140 based on the
information relating to the target object. For example, if the scan
corresponding to the target object relates to a CT scan, the mode
adjustment module 420 may adjust a CT scanner communicating with
the processing device 140.
[0087] In some embodiments, the medical device 110 may perform the
scan on the target object in the work mode based on the scan
protocol.
[0088] In 550, the mode adjustment module 420 (e.g., the analysis
unit 424) may determine that the medical device (e.g., the medical
device 110) has completed the scan performed on the target object.
For example, the mode adjustment module 420 may determine that the
medical device 110 has completed the scan performed on the target
object in response to a determination that the duration of the scan
is longer than a threshold value (e.g., 20 minutes). As another
example, the mode adjustment module 420 may determine that the
medical device 110 has completed the scan performed on the target
object based on a user's input (e.g., pressing a button of
completion).
[0089] In 560, the mode adjustment module 420 (e.g., the analysis
unit 424) may determine whether the medical device (e.g., the
medical device 110) satisfies a condition to get into the standby
mode. For example, the mode adjustment module 420 may determine
that the medical device 110 satisfies a condition to get into the
standby mode in response to a determination that the power
consumption of the medical device 110 at current time is lower than
a threshold power. As another example, the mode adjustment module
420 may determine that the medical device 110 satisfies a condition
to get into the standby mode in response to a determination that
the medical device 110 does not receive any instruction within a
certain time interval (e.g., 10 minutes) from the time when the
scan is completed.
[0090] The process 500 may proceed to 570 to keep the medical
device (e.g., the medical device 110) at the current mode (e.g.,
the work mode) in response to a determination that the medical
device (e.g., the medical device 110) does not satisfy a condition
to get into the standby mode. The process 500 may proceed to 580 to
adjust the medical device (e.g., the medical device 110) to the
standby mode in response to a determination that the medical device
(e.g., the medical device 110) satisfies a condition to get into
the standby mode.
[0091] It should be noted that the above description is merely
provided for the purposes of illustration, and not intended to
limit the scope of the present disclosure. For persons having
ordinary skills in the art, multiple variations and modifications
may be made under the teachings of the present disclosure. However,
those variations and modifications do not depart from the scope of
the present disclosure. For example, before 510, the mode
adjustment module 420 may determine that the medical device 110 is
in the standby mode.
[0092] FIG. 6 is a flowchart illustrating an exemplary process for
adjusting a gantry angle of a medical device according to some
embodiments of the present disclosure. The process 600 may be
implemented in the adjustment system 100 as illustrated in FIG. 1.
For example, the process 600 may be stored in the storage device
150 and/or the storage 220 in the form of instructions (e.g., an
application), and invoked and/or executed by the processing device
140 (e.g., the processor 210 illustrated in FIG. 2, or one or more
modules in the processing device 140 illustrated in FIG. 4). The
operations of the illustrated process presented below are intended
to be illustrative. In some embodiments, the process 600 may be
accomplished with one or more additional operations not described,
and/or without one or more of the operations discussed.
Additionally, the order in which the operations of the process 600
as illustrated in FIG. 6 and described below is not intended to be
limiting.
[0093] In 610, the angle determination module 410 (e.g., the angle
acquisition unit 412) may acquire one or more prior gantry angle
values of a medical device (e.g., the medical device 110). For
example, for a CT scanner, an X-ray source of the CT scanner may
rotate together with a gantry of the CT scanner. A gantry angle
value may indicate a location of the X-ray source. For example, if
the X-ray source is rotated to a location corresponding to 3
o'clock, the gantry angle value is 90.degree.. As another example,
if the X-ray source is rotated to a location corresponding to 9
o'clock, the gantry angle value is 270.degree..
[0094] In some embodiments, a prior gantry angle value may refer to
a gantry angle value that was used in a previous scan prior to the
current time. For example, the angle determination module 410 may
acquire prior gantry angle values used in the past 30 days. In some
embodiments, the one or more prior gantry angle values may
correspond to a same medical device.
[0095] In 620, the angle determination module 410 (e.g., the angle
initialization unit 414) may initialize a gantry angle of the
medical device (e.g., the medical device 110) to Degree 0 (e.g., a
gantry angle) based on the one or more prior gantry angle values.
In some embodiments, the angle determination module 410 may analyze
the one or more prior gantry angle values to determine Degree 0
using a moving average forecast algorithm (e.g., a simple moving
average algorithm, a double moving average algorithm, a three
moving average algorithm), an exponential smoothing forecasting
algorithm (e.g., a simple exponential smoothing algorithm, a double
exponential smoothing algorithm, a three exponential smoothing
algorithm, a Winters exponential smoothing algorithm), a trend
extrapolation forecasting algorithm, a regression forecasting
algorithm, a grey forecasting algorithm, an autoregressive
integrated moving average (ARIMA) algorithm, or the like, or any
combination thereof. In some embodiments, Degree 0 was mostly
frequently used during a certain period (e.g., past 30 days from
the current time) among the one or more prior gantry angle values.
In some embodiments, Degree 0 may be equal to an average value of
the one or more prior gantry angle values.
[0096] In some embodiments, initializing the gantry angle of the
medical device using Degree 0 may reduce the time of adjusting the
X-ray source to a gantry angle for a scan to be performed on the
target object. Description regarding the determination of a gantry
angle value of Degree 0 may be found elsewhere in the present
disclosure. See, e.g., FIG. 7, and the description thereof.
[0097] In some embodiments, 610 may be omitted. The angle
determination module 410 (e.g., the angle initialization unit 414)
may determine Degree 0 based on an input of a user (e.g., a doctor,
an engineer). For example, during a healthy examination of a
plurality of people from a company, because scans performed on the
plurality of people are same, the user of the medical device 110
may set Degree 0 manually and input Degree 0 to the processing
device 140.
[0098] In 630, the angle determination module 410 (e.g., the
adjustment initialization unit 416) may acquire a pre-set gantry
angle Degree 1. In some embodiments, the pre-set gantry angle may
be used to a scan to be performed on the target object. The angle
determination module 410 may acquire the pre-set gantry angle based
on a scan protocol.
[0099] In 640, the angle determination module 410 (e.g., the
adjustment initialization unit 416) may determine whether Degree 0
is equal to Degree 1. The process 600 may proceed to 650 to adjust
the gantry angle from Degree 0 to Degree 1 in response to a
determination that Degree 0 is not equal to Degree 1. The process
600 may proceed to 660 to keep the gantry angle at Degree 0 in
response to a determination that Degree 0 is equal to Degree 1.
[0100] In some embodiments, before 610, the angle determination
module 410 may determine whether a prior scan performed closest to
a current time has been completed by the medical device 110. In
response to a determination that the prior scan performed closest
to the current time has been completed by the medical device 110,
the angle determination module 410 may perform 610-660.
[0101] FIG. 7 is a flowchart illustrating an exemplary process for
determining a gantry angle value based on one or more prior gantry
angle values according to some embodiments of the present
disclosure. The process 700 may be implemented in the adjustment
system 100 illustrated in FIG. 1. For example, the process 700 may
be stored in the storage device 150 and/or the storage 220 in the
form of instructions (e.g., an application), and invoked and/or
executed by the processing device 140 (e.g., the processor 210
illustrated in FIG. 2, or one or more modules in the processing
device 140 illustrated in FIG. 4). The operations of the
illustrated process presented below are intended to be
illustrative. In some embodiments, the process 700 may be
accomplished with one or more additional operations not described,
and/or without one or more of the operations discussed.
Additionally, the order in which the operations of the process 700
as illustrated in FIG. 7 and described below is not intended to be
limiting. In some embodiments, step 620 illustrated in FIG. 6 may
be performed according to the process 700.
[0102] In 710, the angle determination module 410 (e.g., the angle
initialization unit 414) may divide the one or more prior gantry
angle values into one or more groups. In some embodiments, the
angle determination module 410 may put equal prior gantry angle
values into a same group.
[0103] In 720, the angle determination module 410 (e.g., the angle
initialization unit 414) may determine a number of prior gantry
angle values of each of the one or more groups.
[0104] In 730, the angle determination module 410 (e.g., the angle
initialization unit 414) may select, from the one or more groups,
at least one group of which the number of prior gantry angle values
is maximum among the one or more groups.
[0105] In 740, the angle determination module 410 (e.g., the angle
initialization unit 414) may determine whether the number of the
selected at least one group is equal to one. The process 700 may
proceed to 780 to initialize the gantry angle of the medical device
110 to the prior gantry angle value corresponding to the selected
group in response to a determination that the number of the
selected at least one group is equal to one. The process 700 may
proceed to 750 in response to a determination that the number of
the selected at least one group is more than one.
[0106] In 750, the angle determination module 410 (e.g., the angle
initialization unit 414) may obtain a prior time instant
corresponding to each of the prior gantry angle values in the
selected at least one group. The prior time instant may be the time
when the prior gantry angle value was used in a previous scan. The
angle determination module 410 may obtain the prior time instant
from a storage medium (e.g., the storage device 150, the storage
220).
[0107] In 760, the angle determination module 410 (e.g., the angle
initialization unit 414) may determine one of the prior gantry
angle values in the selected at least one group with the prior time
instant closest to the current time.
[0108] In 770, the angle determination module 410 (e.g., the angle
initialization unit 414) may initialize the gantry angle of the
medical device (e.g., the medical device 110) to the one of the
prior gantry angle values in the selected at least one group with
the prior time instant closest to the current time. In some
embodiments, the angle determination module 410 may determine the
one of the prior gantry angle values in the selected at least one
group with the prior time instant closest to the current time as
Degree 0.
[0109] In some embodiments, in response to the determination that
the number of the selected at least one group is more than one, the
angle determination module 410 (e.g., the angle initialization unit
414) may determine an average value of the prior gantry angle
values corresponding to the selected at least one group. The angle
determination module 410 (e.g., the angle initialization unit 414)
may initialize the gantry angle of the medical device 110 to the
average value of the prior gantry angle values corresponding to the
selected at least one group.
[0110] It should be noted that the above description is merely
provided for the purposes of illustration, and not intended to
limit the scope of the present disclosure. For persons having
ordinary skills in the art, multiple variations and modifications
may be made under the teachings of the present disclosure. However,
those variations and modifications do not depart from the scope of
the present disclosure.
[0111] In some embodiments, the processing device 140 may configure
the medical device 110 before performing a medical procedure on a
target object based on the process 500, the process 600, and the
process 700. For example, when the process 500 proceeds to 570
(e.g., the mode adjustment module 420 determines that the medical
device 110 has completed the current scan performed on the target
object and determines that the medical device 110 does not satisfy
a condition to get into the standby mode), the angle determination
module 410 may perform 610 and 620 in the process 600 and/or the
process 700 to initial the gantry angle of the medical device 110.
Another example may be described in FIG. 8.
[0112] FIG. 8 is a flowchart illustrating an exemplary process for
adjusting a gantry angle of a medical device according to some
embodiments of the present disclosure. The process 800 may be
implemented in the adjustment system 100 as illustrated in FIG. 1.
For example, the process 800 may be stored in the storage device150
and/or the storage 220 in the form of instructions (e.g., an
application), and invoked and/or executed by the processing device
140 (e.g., the processor 210 illustrated in FIG. 2, or one or more
modules in the processing device 140 illustrated in FIG. 4). The
operations of the illustrated process presented below are intended
to be illustrative. In some embodiments, the process 800 may be
accomplished with one or more additional operations not described,
and/or without one or more of the operations discussed.
Additionally, the order in which the operations of the process 800
as illustrated in FIG. 8 and described below is not intended to be
limiting. In some embodiments, the process 500 in FIG. 5, the
process 600 in FIG. 6, or the process 700 in FIG. 7 may be applied
to the process 800.
[0113] In 810, the mode adjustment module 420 (e.g., the
information acquisition unit 422) may acquire information relating
to a target object. In some embodiments, before 810, the mode
adjustment module 420 may determine that the medical device 110 is
in a standby mode. Description regarding the acquisition of the
information relating to the target object may be found elsewhere in
the present disclosure. See, e.g., 510 in FIG. 5, and the
description thereof.
[0114] In 820, the mode adjustment module 420 (e.g., the analysis
unit 424) may determine that there is a medical procedure (e.g., a
scan) to be performed on the target object based on the information
relating to the target object. Description regarding the
acquisition of the information relating to the target object may be
found elsewhere in the present disclosure. See, e.g., 520 in FIG.
5, and the description thereof.
[0115] In 830, the angle determination module 410 (e.g., the angle
initialization unit 414) may initialize a gantry angle of a medical
device (e.g., the medical device 110) in response to the
determination. Description regarding the initialization of the
gantry angle may be found elsewhere in the present disclosure. See,
e.g., 610 and 620 in FIG. 6, and the process 700 in FIG. 7, and the
description thereof.
[0116] In 840, the mode adjustment module 420 (e.g., the analysis
unit 422) may determine at least one parameter associated with the
medical procedure to be performed on the target object based on the
information relating to the target object. In some embodiments, the
medical procedure may include a scan performed on the target
object. The at least one parameter may include a scan protocol.
Description regarding the determination of the at least one
parameter may be found elsewhere in the present disclosure. See,
e.g., FIG. 5, and the description thereof.
[0117] In 850, the angle determination module 410 (e.g., the
adjustment initialization unit 416) may adjust the gantry angle of
the medical device based on the at least one parameter before
performing the medical procedure on the target object. Description
regarding the adjustment of the gantry angle may be found elsewhere
in the present disclosure. See, e.g., 630-660 in FIG. 6, and the
description thereof.
[0118] It should be noted that the above description is merely
provided for the purposes of illustration, and not intended to
limit the scope of the present disclosure. For persons having
ordinary skills in the art, multiple variations and modifications
may be made under the teachings of the present disclosure. However,
those variations and modifications do not depart from the scope of
the present disclosure. For example, 830 may be performed before or
after 840. As another example, 830 and 840 may be performed
simultaneously.
[0119] Having thus described the basic concepts, it may be rather
apparent to those skilled in the art after reading this detailed
disclosure that the foregoing detailed disclosure is intended to be
presented by way of example only and is not limiting. Various
alterations, improvements, and modifications may occur and are

of the disclosure, it is to be understood that such detail is
solely for that purpose, and that the appended claims are not
limited to the disclosed embodiments, but, on the contrary, are
intended to cover modifications and equivalent arrangements that
are within the spirit and scope of the disclosed embodiments. For
example, although the implementation of various components
described above may be embodied in a hardware device, it may also
be implemented as a software only solution, e.g., an installation
on an existing server or mobile device.
[0125] Similarly, it should be appreciated that in the foregoing
description of embodiments of the present disclosure, various
features are sometimes grouped together in a single embodiment,
figure, or description thereof for the purpose of streamlining the
disclosure aiding in the understanding of one or more of the
various embodiments. This method of disclosure, however, is not to
be interpreted as reflecting an intention that the claimed subject
matter requires more features than are expressly recited in each
claim. Rather, claimed subject matter may lie in less than all
features of a single foregoing disclosed embodiment.
