Description

[Technical field]

[0001] The present invention relates to a dynamic radiography support device, a program, and a dynamic radiography support method. [Background technology]

[0002] Clinical research into dynamic analysis using dynamic images such as X-rays is progressing, and it has become clear that dynamic analysis is useful in testing for a variety of diseases. In the current protocol for dynamic imaging, imaging is performed uniformly, and all dynamic analysis processing is performed after imaging. Uniformity means that dynamic imaging is performed comprehensively under imaging conditions suitable for all dynamic analysis processing. In the case of such a protocol, if the number of types of dynamic analysis increases in the future, the processing burden of the dynamic analysis will also increase accordingly. In addition, since the optimal imaging conditions differ for each dynamic analysis, when all dynamic analyses are performed, the number of imaging with different imaging conditions will increase, which will also be a heavy burden on the patient.

[0003] The following documents disclose techniques for specifying the type of dynamic analysis and imaging conditions. Patent Document 1 describes a dynamic analysis device that determines the type of dynamic analysis to be applied to a dynamic image based on image attendant information related to the dynamic image and setting information stored in a setting storage unit. Patent Document 2 describes a dynamic imaging condition selection device that selects a frame rate, which is one of the imaging conditions for dynamic imaging, based on information related to an observation target in the dynamic imaging.

[0012] Preferred embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0013] First Embodiment [Example of the configuration of the radiation image capturing system 100] FIG. 1 is a diagram showing a schematic configuration of a radiation image capturing system 100 according to the first embodiment. The radiation image capturing system 100 includes a radiation image capturing device 1, an image capturing control device 2A which is an example of a dynamic image capturing support device, a radiation generator 3, a dynamic analysis device 4, and an HIS / RIS 5. In the following, the radiation image capturing device may be referred to as an image capturing device 1, and the radiation generator may be referred to as a generator 3. HIS is an abbreviation for Hospital Information System, and is also called a hospital information system. RIS is an abbreviation for Radiology Information System, and is also called a radiology information system. Each device constituting the radiation image capturing system 100 conforms to a standard, and communication between each device is performed in accordance with DICOM. DICOM is an abbreviation for Digital Image and Communications in Medicine.

[0014] The imaging device 1, imaging control device 2A, generating device 3, dynamic analysis device 4, and HIS / RIS 5 are communicatively connected via a network N. Examples of the network N include a LAN, a WAN, and the Internet. LAN is an abbreviation for Local Area Network. WAN is an abbreviation for Wide Area Network. The communication method of the network N may be wired communication or wireless communication.

[0015] The generating device 3 includes a generator 31 , an irradiation instruction switch 32 , and a radiation source 33 . The generator 31 applies a voltage according to preset imaging conditions to a radiation source 33 including, for example, a tube, based on the operation of an irradiation instruction switch 32. The generator 31 may have an operation unit that accepts input of irradiation conditions and the like.

[0016] When a voltage is applied from the generator 31 to the radiation source 33, the radiation source 33 generates radiation R with a dose corresponding to the applied voltage. The radiation R is, for example, an X-ray.

[0017] The generator 3 generates radiation R in a manner corresponding to the type of radiation image, for example, dynamic radiography. Dynamic radiography refers to obtaining a series of images of a subject by repeatedly irradiating a subject with pulsed radiation R, such as X-rays, at a predetermined time interval in response to one radiography operation. Repeated irradiation of pulsed radiation at a predetermined time interval is called pulse irradiation. Alternatively, dynamic radiography refers to obtaining a series of images of a subject by continuously irradiating a subject with a low dose rate without interruption in response to one radiography operation. Continuous irradiation of radiation without interruption is called continuous irradiation.

[0018] A series of images obtained by dynamic shooting is called a dynamic image. Also, each of all images that compose a dynamic image is called a frame image. Here, dynamic shooting includes video shooting, but does not include shooting still images while displaying a video. Also, dynamic images include video, but do not include images obtained by shooting still images while displaying a video.

[0019] The imaging device 1 generates digital image data showing the imaging region of the subject S. For example, a portable FPD is used as the imaging device 1. FPD is an abbreviation for Flat Panel Detector. The imaging device 1 may be configured integrally with the generating device 3.

[0020] Although not shown, the imaging device 1 includes, for example, an imaging element, a sensor board, a scanning unit, a readout unit, a control unit, and a communication unit. The imaging element generates an electric charge according to the dose when exposed to radiation R. The sensor board has switch elements arranged two-dimensionally (in a matrix) and stores and releases electric charge. The scanning unit switches each switch element on / off. The readout unit reads out the amount of electric charge released from each pixel as a signal value. The control unit generates image data of the radiation image from the multiple signal values ​​read out by the readout unit. The image data includes dynamic image data. The communication unit transmits the generated image data and various signals to other devices such as the imaging control device 2A, and receives various information and various signals from other devices.

[0021] The imaging control device 2A sets imaging conditions for the imaging device 1 and the generator 3, etc., and controls the reading operation of the radiation image captured by the imaging device 1. The imaging control device 2A is also called a console, and is composed of, for example, a personal computer, etc. For example, the imaging control device 2A identifies the type of dynamic analysis from information on the imaging purpose included in the examination order information transmitted from the HIS / RIS5. Next, the imaging control device 2A identifies information on the imaging conditions from the information on the identified type of dynamic analysis. In this embodiment, the information on the imaging purpose (first information) is called imaging purpose information Ia. The information on the type of dynamic analysis (second information) is called dynamic analysis information Ib. The information on the imaging conditions (third information) is called imaging condition information Ic.

[0022] The imaging condition information Ic includes, for example, patient conditions related to the subject S, irradiation conditions related to the irradiation of radiation R, and image reading conditions related to the image reading of the imaging device 1. The patient conditions include, for example, the imaging part, imaging direction, and physique. The irradiation conditions include, for example, tube voltage (kV), tube current (mA), irradiation time (ms), and current-time product (mAs value). The image reading conditions include, for example, pixel size, image size, and frame rate. The imaging control device 2A may automatically set the imaging condition information Ic based on order information acquired from the HIS / RIS 5, etc. Alternatively, the imaging control device 2A may set the imaging condition information Ic manually by a user, such as a radiologist, operating the operation unit 21, which will be described later.

[0023] The dynamic analysis device 4 executes a predetermined dynamic analysis process on the dynamic image captured by the imaging device 1. Examples of types of dynamic analysis include chest bone attenuation processing (BS mode), specific component tracking processing (DM mode), frequency emphasis processing (FE mode), and lung tissue movement detection processing (LM mode). Examples of other types of dynamic analysis include reference frame ratio calculation processing (PL mode), cross-correlation calculation processing (PH mode), cross-correlation calculation processing 2 (PH2 mode), and airway diameter measurement (TD mode). Note that the types of dynamic analysis listed in this embodiment are examples, and other dynamic analyses and dynamic analyses to be developed in the future can be added as appropriate. In addition, hereinafter, chest bone attenuation processing may be referred to as BS mode, specific component tracking processing may be referred to as DM mode, frequency emphasis processing may be referred to as FE mode, and lung tissue movement detection processing may be referred to as LM mode. In addition, reference frame ratio calculation processing may be referred to as PL mode, cross-correlation calculation processing may be referred to as PH mode, cross-correlation calculation processing 2 may be referred to as PH2 mode, and airway diameter measurement may be referred to as TD mode.

[0024] The BS mode is a process that attenuates signals corresponding to the clavicle and ribs in the lung field. The DM mode is a process that tracks the up and down movement of the lung apex and diaphragmatic ridge, and quantifies the amount of up and down movement of the lung apex and diaphragmatic ridge. The FE mode is a process that emphasizes the movement of structures with specific frequencies (pulmonary tissues). The LM mode is a process that tracks signal value patterns including vascular shadows in the lung field, measures the amount of movement of each area associated with breathing, and displays the tendency of movement in color, or displays the amount of movement of each area associated with breathing based on the maximum inspiration frame as a vector. The PL mode is a process that extracts signal changes of lung tissue behavior associated with breathing from the original image (raw image) and visualizes signal changes from the maximum expiration position. The PH mode is a process that extracts signal changes in the lung field synchronized with the heartbeat from the original image, and visualizes signal changes synchronized with the heartbeat. PH2 mode is a process that visualizes the amount of change in high frequency signals in the lung field synchronized with the heartbeat (≒change in blood flow volume), and compared to PH mode, it can express minute changes in blood flow. TD mode extracts the tracheal wall, measures the change in tracheal diameter with breathing, and automatically measures the change in tracheal diameter. It is a process that displays the maximum and minimum diameters.

[0025] The HIS / RIS 5 receives examination order information from, for example, a doctor, and transmits the received examination order information to the imaging control device 2A. The examination order information includes various information such as patient information, imaging type, imaging part, imaging direction, medical department, imaging purpose, etc. Patient information includes, for example, patient ID, patient name, sex, age, presence or absence of disease, etc. Imaging type includes, for example, dynamic image and still image.

[0026] [Example of block diagram of imaging control device 2A] Next, a detailed configuration of the imaging control device 2A will be described below. Fig. 2 is a block diagram of the imaging control device 2A according to the first embodiment.

[0027] The imaging control device 2A includes a control unit 20, an operation unit 21, a display unit 22, a storage unit 23, and a communication unit 24. The control unit 20, the operation unit 21, the display unit 22, the storage unit 23, and the communication unit 24 are connected to each other so as to be able to communicate with each other via a bus 25, for example.

[0028] The control unit 20 includes, for example, a processor such as a CPU and a memory. CPU is an abbreviation for Central Processing Unit. The control unit 20 executes a program stored in, for example, a memory such as a RAM, the storage unit 23, etc., to realize a process of identifying dynamic analysis information Ib and imaging condition information Ic from imaging purpose information Ia. The control unit 20 may include an electronic circuit such as an ASIC or an FPGA. ASIC is an abbreviation for Application Specific Integrated Circuit. FPGA is an abbreviation for Field Programmable Gate Array.

[0029] In this embodiment, the control unit 20 functions as an acquisition unit (acquisition step), a determination unit (determination step), and an output unit (output step). The processor of the control unit 20 executes a program stored in the storage unit 23 or the like to realize the functions of the acquisition unit, the determination unit, and the output unit. The acquisition unit acquires imaging purpose information Ia for dynamic imaging for capturing dynamic images of the subject S from examination order information, etc. The identification unit identifies imaging condition information Ic from dynamic analysis information Ib associated with the imaging purpose information Ia acquired by the acquisition unit. When the imaging purpose information Ia included in the examination order information from the HIS / RIS5 is insufficient, the identification unit may identify an optimal type of dynamic analysis, etc., by considering past records, similar imaging purposes, etc. The output unit outputs at least one of the dynamic analysis information Ib and the imaging condition information Ic identified by the identification unit to the display unit 22, etc.

[0030] The operation unit 21 receives instructions according to various input operations from the user, converts the received instructions into operation signals, and outputs the operation signals to the control unit 20. The operation unit 21 includes, for example, a mouse, a keyboard, a switch, a button, and the like. The operation unit 21 may be, for example, a touch panel integrally combined with a display. The operation unit 21 may be, for example, a user interface that receives voice input from a microphone or the like.

[0031] The display unit 22 displays a radiographic image based on image data received from the imaging device 1, and a GUI for receiving various input operations from the user. GUI is an abbreviation for Graphical User Interface. Specifically, the display unit 22 displays dynamic analysis information Ib and imaging condition information Ic, etc., specified by imaging purpose information Ia, on an imaging screen. The display unit 22 is, for example, a display such as a liquid crystal display or an organic EL display. EL is an abbreviation for Electro Luminescence.

[0032] The storage unit 23 stores, for example, a system program, an application program, and various data. Specifically, the storage unit 23 stores a table 23a for identifying dynamic analysis information Ib and imaging condition information Ic required for imaging purpose information Ia. Details of the table 23a will be described later. The storage unit 23 includes any storage module, for example, an HDD, an SSD, a ROM, and a RAM. HDD is an abbreviation for Hard Disk Drive. SSD is an abbreviation for Solid State Drive. ROM is an abbreviation for Read Only Memory.

[0033] The communication unit 24 includes, for example, a communication module including a NIC, a receiver, and a transmitter. NIC is an abbreviation for Network Interface Card. The communication unit 24 communicates various data such as image data between the imaging device 1 and the dynamic analysis device 4 via the network N.

[0034] [Example of table 23a] Next, a description will be given of the table 23a stored in the storage unit 23. Fig. 3 shows an example of the configuration of the table 23a stored in the storage unit 23 according to the first embodiment. The table 23a functions as an example of a saving unit.

[0035] The table 23a is a table for identifying the dynamic analysis information Ib and the imaging condition information Ic required to realize the imaging purpose in the dynamic imaging of the patient. The table 23a stores the dynamic analysis information Ib and the imaging condition information Ic in correspondence with the imaging purpose information Ia. The table 23a may be configured so that each item of the dynamic analysis information Ib and the imaging condition information Ic can be appropriately customized for each facility, for example. The imaging purpose information Ia, the dynamic analysis information Ib, and the imaging condition information Ic are not limited to the item contents of the table 23a shown in FIG. 3.

[0036] For example, when the imaging purpose information Ia is "medical examination", it is necessary to check the possibility of various diseases before the patient's illness is identified. Therefore, all types of dynamic analysis are selected as the dynamic analysis information Ib. The imaging condition information Ic, such as the frame rate and imaging time, is set to values ​​that can correspond to the movement of the chest, which is mainly imaged in the "medical examination", and can correspond to all types of dynamic analysis.

[0037] For example, when the imaging purpose information Ia is "before lung resection surgery", the patient's illness is identified, and it is only necessary to confirm whether the remaining parts after lung resection are functioning normally. Therefore, as the dynamic analysis information Ib, in addition to the original image (original image), two types of PL mode and PH2 mode are selected. As the imaging condition information Ic such as the frame rate and imaging time, values ​​that can correspond to the movement of the circulatory system and can correspond to the PL mode and PH2 mode are set.

[0038] For example, when the imaging purpose information Ia is "after lung resection surgery", it is necessary to check whether the organs around the lungs are functioning normally in addition to the lungs. Therefore, all types of dynamic analysis are selected as the dynamic analysis information Ib. As the imaging condition information Ic such as the frame rate and imaging time, values ​​that can correspond to the movements of each organ including the lungs and can correspond to all types of dynamic analysis are set.

[0039] For example, when the imaging purpose information Ia is "intensive care unit", the illness of the patient is specified to some extent. Therefore, in addition to the original image (original image), the LM mode is selected as the dynamic analysis information Ib. Values ​​compatible with the LM mode are set as the imaging condition information Ic such as the frame rate and imaging time.

[0040] [Operation example of the imaging control device 2A] Next, a flow of the dynamic imaging support method during dynamic imaging according to the first embodiment will be described. Fig. 4 is a flow chart showing an example of the operation of the imaging control device 2A during dynamic imaging according to the first embodiment. The control unit 20 realizes the processing of each step shown in Fig. 4 by executing a program stored in a memory such as the storage unit 23.

[0041] The control unit 20 acquires examination order information including imaging purpose information Ia from the HIS / RIS 5 (step S1). The imaging purpose information Ia includes, for example, medical examination, pre-lung resection surgery, post-lung resection surgery, intensive care unit (ICU), etc. Pre-lung resection surgery and post-lung resection surgery are examples of examination of a specific site. The imaging purpose information Ia may be acquired by inputting information in the imaging control device 2A in addition to being acquired from the HIS / RIS 5. For example, a doctor may communicate an imaging purpose to a radiology technician by telephone or the like. In this case, the technician inputs the imaging purpose information Ia by operating the operation unit 21 of the imaging control device 2A.

[0042] The control unit 20 specifies the dynamic analysis information Ib corresponding to the acquired imaging purpose information Ia (step S2). For example, the control unit 20 refers to the table 23a and acquires the dynamic analysis information Ib associated with the imaging purpose information Ia. When the imaging purpose information Ia is "medical examination", the control unit 20 acquires all types of dynamic analysis as the dynamic analysis information Ib. When the imaging purpose information Ia is "before lung resection surgery", the control unit 20 acquires two types of PL mode and PH2 mode in addition to the original mode as the dynamic analysis information Ib.

[0043] The process of identifying the dynamic analysis information Ib may be performed on the dynamic analysis device 4 side. The communication unit 24 of the imaging control device 2A transmits the imaging purpose information Ia acquired from the HIS / RIS 5 to the dynamic analysis device 4. The dynamic analysis device 4 receives the imaging purpose information Ia and identifies the dynamic analysis information Ib required for the received imaging purpose information Ia. The dynamic analysis device 4 transmits the identified dynamic analysis information Ib to the imaging control device 2A. The communication unit 24 of the imaging control device 2A receives the dynamic analysis information Ib transmitted from the dynamic analysis device 4.

[0044] The control unit 20 specifies the imaging condition information Ic corresponding to the specified dynamic analysis information Ib (step S3). For example, the control unit 20 refers to the table 23a and acquires the imaging condition information Ic associated with the specified dynamic analysis information Ib. When the imaging purpose information Ia is "medical examination" and the dynamic analysis information Ib is all modes, the control unit 20 acquires "frame rate: 7.5 fps", "imaging time: 15 seconds", "imaging dose 1 mGy", etc. as the imaging condition information Ic. When the imaging purpose information Ia is "before lung resection surgery" and the dynamic analysis information Ib is PL mode and PH2 mode, the control unit 20 acquires "frame rate: 15 fps", "imaging time: 7.5 seconds", "imaging dose 1 mGy", etc. as the dynamic analysis information Ib.

[0045] The control unit 20 causes the specified dynamic analysis information Ib and imaging condition information Ic to be displayed on the imaging screen 220 of the display unit 22 (step S4). FIG. 5 shows an example of the dynamic analysis information Ib and the imaging condition information Ic displayed on the imaging screen 220 of the display unit 22 according to the first embodiment. The imaging screen 220 is provided with an imaging selection section 221, a condition setting section 222, an image display area 223, a patient information display section 224, and an examination end button 225. The imaging selection section 221 displays, for example, order information selected in the examination list. The order information includes, for example, imaging details such as the imaging part and imaging direction, and thumbnail images showing the captured radiographic images. The condition setting section 222 is provided with, for example, a button for setting imaging conditions for the radiographic images, a button for adjusting the images of the captured radiographic images, and the like.

[0046] The image display area 223 displays a radiographic image captured by the imaging device 1 based on the set imaging conditions, etc. In FIG. 5, since the radiographic image has not yet been captured, the image display area 223 does not display the radiographic image. The image display area 223 also displays dynamic analysis information Ib and imaging condition information Ic. For example, when the imaging purpose information Ia is "before lung resection surgery", the dynamic analysis information Ib is displayed as PL mode and PH2 mode, and the imaging condition information Ic is displayed as frame rate: 15 fps, imaging time: 7.5 seconds, and imaging dose: 1 mGy. This allows the user to check the type of dynamic analysis specified before dynamic imaging, and thus to determine in advance whether the imaging conditions are suitable for dynamic analysis.

[0047] In FIG. 5, only the type of dynamic analysis that has been specified is displayed on the imaging screen 220 as the dynamic analysis information Ib, but this is not limiting. Specifically, in addition to displaying the type of dynamic analysis that has been specified, the type of dynamic analysis that has not been specified may be displayed in a different display method from the type of dynamic analysis that has been specified. For example, the type of dynamic analysis that has not been specified may be displayed in a grayed-out state. In addition, the display position of the dynamic analysis information Ib and the imaging condition information Ic is not limited to the image display area 223, and may be, for example, an empty space in the condition setting section 222, etc.

[0048] The control unit 20 sets the identified imaging condition information Ic to the imaging device 1 and the generator 3 (step S5). For example, the control unit 20 sets image reading conditions such as a frame rate, a pixel size, and an image size to the imaging device 1. The control unit 20 sets radiation irradiation conditions such as an imaging dose (mGy), a tube voltage (kV), a tube current (mA), and an irradiation time (ms) of the radiation source 33 to the generator 3. The imaging conditions may be automatically set by the control unit 20 as described above, or may be manually set by the user. For example, the user may set the image reading conditions to the imaging device 1 by operating the operation unit 21 of the imaging control device 2A. The user may also set the radiation irradiation conditions by operating the operation panel of the generator 3. This allows the user to change the dynamic analysis information Ib and the imaging condition information Ic as appropriate by operating the operation unit 21 after checking the imaging screen 220.

[0049] A user such as a radiologist guides a patient, who is the subject S, between the radiation source 33 of the generating device 3 and the imaging device 1, and positions the patient according to the part to be imaged and the imaging direction, etc. Once positioning is complete, the user turns on the irradiation instruction switch 32. When the user turns on the irradiation instruction switch 32, the generating device 3 irradiates the part to be imaged of the subject S with radiation R. The imaging device 1 captures the dynamics of the part to be imaged at the time it receives radiation R from the generating device 3, and generates a dynamic image made up of multiple frame images. The imaging device 1 transmits the generated dynamic image data to the imaging control device 2A.

[0050] The control unit 20 of the imaging control device 2A stores the acquired dynamic image data in the storage unit 23, and displays a preview of the acquired dynamic image on the imaging screen 220 of the display unit 22 (step S6). The user checks the positioning, image quality, etc. of the dynamic image displayed on the imaging screen 220, and judges whether the image is suitable for diagnosis.

[0051] When the control unit 20 receives input from the user indicating that the dynamic image is suitable for diagnosis, it transmits the dynamic image data and the additional information to the dynamic analysis device 4 (step S7). The additional information includes, for example, an identification ID, patient information, and examination information. The examination information includes, for example, analysis information indicating the imaging area, imaging direction, radiation irradiation conditions, image reading conditions, frame number, medical department, and type of analysis information. On the other hand, when the control unit 20 receives input from the user indicating that the dynamic image is unsuitable for diagnosis, it performs re-imaging.

[0052] The dynamic analysis device 4 receives dynamic image data and associated information from the imaging control device 2A. The dynamic analysis device 4 performs analysis processing on the received dynamic image data according to the type (each mode) of dynamic analysis included in the associated information. The dynamic analysis device 4 transmits the results of the analysis processing to the image management device in association with the dynamic image data, etc. The image management device stores and manages the received dynamic image data and the results of the analysis processing, etc.

[0053] As described above, in the first embodiment, the dynamic imaging support device such as the imaging control device 2A specifies the dynamic analysis information Ib required for the imaging purpose information Ia in the dynamic imaging of the patient, and further specifies the imaging condition information Ic required for the imaging purpose information Ia and the dynamic analysis information Ib. This makes it easier to obtain the dynamic analysis information Ib and the imaging condition information Ic suitable for the imaging purpose information Ia compared to the conventional method. Therefore, while the dynamic analysis information Ib was set uniformly for the imaging purpose information Ia in the conventional method, the imaging purpose information Ia and the dynamic analysis information Ib suitable for the imaging purpose information Ia can be automatically specified according to the first embodiment. Therefore, waste of dynamic imaging and dynamic analysis processing can be reduced. Therefore, the radiologist and the image interpretation doctor can avoid unnecessary imaging and dynamic analysis processing, and the workload can be reduced. In addition, the burden on the patient during medical examinations can be reduced because unnecessary imaging can be omitted.

[0054] Furthermore, according to the first embodiment, the specified dynamic analysis information Ib and imaging condition information Ic are displayed on the imaging screen 220, so that a user such as a radiologist can check whether the type of dynamic analysis and imaging conditions suitable for the imaging purpose are selected before dynamic imaging. This allows a user such as a radiologist to add or modify the type of dynamic analysis and imaging conditions while checking the characteristics of the actual patient.

[0055] <Second embodiment> In the second embodiment, a machine learning model (trained model) is used to estimate the type of dynamic analysis and imaging conditions suitable for the imaging purpose. In the second embodiment, differences from the first embodiment will be mainly described, and descriptions of commonalities with the first embodiment will be omitted. In addition, in the description of the second embodiment, parts common to the first embodiment will be described with the same reference numerals.

[0056] FIG. 6 shows an example of the configuration of an imaging control device 2B of the radiation image capturing system 100 according to the second embodiment. The imaging control device 2B includes a control unit 20, an operation unit 21, a display unit 22, a storage unit 23, and a communication unit 24. A machine learning model (trained model) 23b is stored in the storage unit 23. The machine learning model 23b may be provided in an external information processing device.

[0057] The machine learning model 23b is created by learning using a data set consisting of input data and correct output data. The input data includes information including the imaging purpose such as medical examination. The output data includes information regarding the type (mode) of dynamic analysis required for the imaging purpose and information regarding imaging conditions required for the type of dynamic analysis. The machine learning model 23b may be another model such as a neural network. The machine learning model 23b may be a regression model such as polynomial regression, multiple regression, support vector regression, or random forest regression. Note that a model for estimating optimal dynamic analysis information Ib for imaging purpose information Ia and a model for estimating optimal imaging condition information Ic for dynamic analysis information Ib may be provided separately.

[0058] The control unit 20 estimates the correct dynamic analysis information Ib and the imaging condition information Ic by inputting the imaging purpose information Ia included in the examination order information to the machine learning model 23b. As a result, the control unit 20 can specify the dynamic analysis information Ib optimal for the imaging purpose information Ia, and specify the optimal imaging condition information Ic from the specified dynamic analysis information Ib. The control unit 20 functions as a specification unit.

[0059] According to the second embodiment, by using the machine learning model 23b, it is possible to easily identify the dynamic analysis information Ib suitable for the imaging purpose information Ia and the imaging condition information Ic suitable for the dynamic analysis information Ib.
