Description

Technical Field

[0001] The present invention relates to a radiographic imaging assistance apparatus, a radiographic imaging assistance method, and a program.

Background Art

[0002] Conventionally, when a user such as an imaging technologist makes a ward round to visit patients in a medical facility such as a hospital, a radiographic (X-ray) image of a patient is captured at the round destination. In this case, the user performs imaging with a mobile radiographic apparatus (round vehicle) using an FPD (Flat Panel Detector). At the round destination, there are cases where one patient is imaged, and there are also cases where a plurality of patients are imaged consecutively. It is necessary to go to the round destination in a form prepared for such an imaging situation at the round destination.

[0003] For example, when imaging with a round vehicle is set, the X-ray imaging apparatus described in Patent Document 1 determines to use the wireless sensor (FPD) having the largest remaining battery capacity among the plurality of wireless sensors (FPDs), regardless of imaging conditions.

[0004] On the other hand, generally, when a user performs imaging at a round destination, the user first goes to a standby location where FPDs and round vehicles are stored. Next, the user selects the FPD and round vehicle to be used for imaging. Then, the user brings the selected FPD and round vehicle to the round destination and performs imaging. Imaging at such a round destination has the following problems compared to general imaging performed in an imaging room. Specifically, when selecting an FPD to be used for imaging, since the patient to be imaged is not present on site, the user cannot directly check the patient as in general imaging, and cannot determine the size of the FPD to be brought to the round destination based on the patient's physique or the like. Furthermore, since patients may be unable to move during imaging at patient sites, fixation devices or assistive devices may be necessary to immobilize them. However, when selecting fixation devices or assistive devices to use for imaging, the user cannot directly examine the patient as in general radiography, as the patient being imaged is not present at the site. Therefore, it is not possible to determine which fixation devices or assistive devices to bring to the patient site based on the patient's condition. Furthermore, when selecting the fixation jigs and auxiliary equipment to be used for imaging, users cannot directly check the environment of the ward or other location they are visiting, as they cannot determine which fixation jigs and auxiliary equipment to bring to the location based on the environment of the location they are visiting. Furthermore, if there are no terminals such as electronic medical records or RIS (Radiology Information Systems) nearby at the hospital where the rounds are being conducted, and if the communication environment in the ward or other area is unreliable, the user may not be able to confirm the necessary imaging equipment at the hospital. This imaging equipment includes FPDs, mobile warding units, fixing jigs, and auxiliary devices. While experienced technicians can select such imaging equipment based on their experience, this is merely the bare minimum selection and not necessarily the optimal choice. Furthermore, it is even more difficult for less experienced technicians. [Prior art documents] [Patent Documents]

[Modes for carrying out the invention]

[0024] Embodiments of the present invention will be described in detail with reference to the attached drawings. However, the present invention is not limited to the illustrated examples.

[0025] <1. Configuration of the radiography system> First, the configuration of this embodiment will be described with reference to Figures 1 and 2. Figure 1 is a schematic diagram showing the radiography system 100. Figure 2 is a block diagram showing the configuration of the mobile medical unit RC.

[0026] The radiography system 100 shown in Figure 1 is installed in medical facilities such as hospitals. A user U, such as a radiographer at a medical facility, moves to the ward, operating room, or other location where the patient is located, along with the radiography system 100, during rounds to perform radiography on the patient. Here, we will explain an example where the rounds are conducted in a ward, a bed B is set up in the ward, and the patient S, who is the subject of the examination, is in a supine position on the raised bed B while radiography is performed.

[0027] The radiography system 100 comprises an FPD1, which is a radiographic imaging device, and a mobile radiography vehicle RC. The FPD1 and the mobile medical unit RC can communicate with each other, for example, via wireless communication.

[0028] FPD1 is a device that generates radiation image data corresponding to the radiation R emitted from radiation generator 2. The FPD1 is configured as a panel and is portable. User U can use the FPD1 by loading it onto the imaging table. User U can also use the FPD1 by positioning it horizontally between the subject S, who is lying down on the bed B, and the bed B. Furthermore, as shown in Figure 1, User U can use the FPD1 by positioning it upright between the subject S, who is sitting on the raised bed B or wheelchair, and the backrest.

[0029] The FPD1 includes, for example, a scintillator, a PD (photodiode), a TFT (thin film transistor) switch, etc. (none of which are shown in the diagram). The scintillator converts incident radiation R into light. The PDs are arranged in a matrix corresponding to the pixels. The TFT switch is arranged corresponding to each PD. The incident radiation R is converted into light by the scintillator and incident on the PD, where it is accumulated as charge in each pixel. The charge accumulated in the PD flows out through the TFT switch and signal lines, is amplified, A / D converted, and output as radiation image data to the mobile medical unit RC. Furthermore, FPD1 may be of the indirect conversion type described above, or it may be of the direct conversion type that directly converts radiation R into an electrical signal.

[0030] As shown in Figure 2, the mobile RC unit can communicate with the RIS40 via the communication network N. The mobile RC unit may also communicate with the electronic medical record system, consoles of other radiography systems, other mobile RC units, PACS (Picture Archiving and Communication System), other examination equipment, bed systems, etc., via the communication network N. Furthermore, the communication network N is assumed to be wireless, but it may also be wired.

[0031] The mobile medical unit RC has a radiation generator 2 and a console 3.

[0032] The radiation generator 2 comprises a generator body 21, an irradiation instruction switch 22, a light tube 23, a light tube support 24, a collimator 25, and an FPD storage unit 26. The radiation generator 2 is also movable by wheels 27 provided on the housing of the generator body 21.

[0033] The irradiation instruction switch 22 outputs an operation signal to the generator main unit 21 when it is operated (pressed) by the user U. Figure 1 illustrates a configuration where the irradiation instruction switch 22 is connected to the generator main unit 21 by a wire. However, the irradiation instruction switch 22 and the generator main unit 21 may be connected wirelessly.

[0034] When the irradiation instruction switch 22 is operated, the tube 23 generates radiation R (such as X-rays) in a manner corresponding to the preset imaging conditions, at a dose corresponding to those conditions. The tube 23 then irradiates the generated radiation R from the irradiation port.

[0035] The tube support section 24 is an arm that supports the tube 23. The tube support section 24 has a support section 241 extending upward from the main body of the generator 21, and a support section 242 extending forward from the upper part of the support section 241. The tip of the support section 242 supports the tube 23. Furthermore, the tube support section 24 has a joint mechanism (not shown) that allows the tube 23 to be moved in the X-axis direction, the Y-axis direction perpendicular to the X-axis, and the Z-axis direction perpendicular to both the X and Y axes. In Figure 1, the X-axis direction is the left-right direction of Figure 1, that is, the front-to-back direction of the radiation generator 2. In Figure 1, the Y-axis direction is the direction perpendicular to the plane of Figure 1, that is, the width direction of the radiation generator 2. In Figure 1, the Z-axis direction is the up-and-down direction of Figure 1, that is, the vertical direction. Furthermore, the tube support section 24, by means of a joint mechanism (not shown), can rotate the tube 23 around a rotation axis parallel to the X, Y, and Z axes to change the direction of the radiation port R.

[0036] The collimator 25 is attached to the irradiation port of the tube 23 and focuses the radiation R emitted from the irradiation port so that the irradiation field of the radiation R becomes a predetermined rectangular shape. Furthermore, the collimator 25 is equipped with a lamp button (not shown). When the lamp button is operated by the user, visible light is irradiated into the area that will be the irradiation field of radiation R.

[0037] The FPD storage unit 26 is located on the side of the generator body 21 and stores the FPD1 when not in use. The FPD storage unit 26 can store one or more FPD1. The FPD storage unit 26 may be configured to include a connector (not shown) that connects to the connector (not shown) on the FPD 1 when the FPD 1 is stored inside.

[0038] Console 3 consists of a PC (Personal Computer), a mobile terminal, or a dedicated device, and is mounted on top of the radiation generator 2. Console 3 can set imaging conditions for at least one of the FPD1 and the radiation generator 2. The imaging conditions include tube voltage, tube current and irradiation time or current-time product (mAs value), imaging area, and imaging direction. In the case of motion imaging, these imaging conditions also include the frame rate. Furthermore, the shooting conditions are based on inspection information acquired from an external device such as RIS40, or on operations performed on the control unit 32 by the user U. Examination information refers to the information regarding radiographic imaging requested by clinicians from users. Furthermore, Console 3 can acquire the radiation image data generated by FPD1 and either save it to itself or transmit it to other external devices (such as PACS).

[0039] A seated radiograph using the radiography system 100 configured in this way is performed as follows. First, user U places the radiography system 100 near the patient S, such as beside bed B. Then, user U has the patient S assume a seated position. If the patient S is sitting on an adjustable bed B or other device, user U adjusts the angle of the bed B's backrest as appropriate. Then, user U adjusts the approximate position and orientation of the radiography tube 23 so that its irradiation port faces the area of ​​the patient S being photographed. Next, user U takes the FPD 1 from the FPD storage unit 26 and places the FPD 1 between the patient S's back and the backrest. Then, user U fine-tunes the orientation and irradiation field of the radiography tube 23 so that the irradiation axis of the radiation R is perpendicular to the radiation incident plane of the FPD 1. Finally, user U performs radiography. In other words, user U irradiates the area of ​​the subject S with radiation R using the light tube 23, and generates radiographic image data of a still or moving image of the area to be diagnosed using the FPD 1.

[0040] In this embodiment, the generator body 21 and the console 3 are housed together in a single enclosure and integrated into one unit, but they may be separate units. Furthermore, the radiation generator 2 may be movable by means other than the wheels 27. For example, the radiation generator 2 may be lightweight enough to be carried by a person or mounted on a commercially available trolley or the like. Also, the radiation generator 2 may have a smooth bottom surface that allows it to slide against the floor. Furthermore, the radiation generator 2 of the radiography system 100 may be installed in a room in a medical facility or similar location.

[0041] Next, with reference to Figure 2, the internal configuration of the radiation generator 2 and console 3 of the mobile medical unit RC will be described. The radiation generator 2 further includes an optical imaging unit 28. Furthermore, the main body of the generator 21 includes a control unit 211, a storage unit 212, a generator 213, and a communication unit 214. All parts of the radiation generator 2, excluding the light tube 23, are connected in a way that allows for communication.

[0042] The optical imaging unit 28 includes an optical system such as a lens and an image sensor such as a CCD (Charge Coupled Device) or CMOS (Complementary Metal Oxide Semiconductor). In this embodiment, the optical imaging unit 28 is provided in the housing of the collimator 25. However, the optical imaging unit 28 may also be provided in the housing of the tube 23 or the tube support unit 24. The optical imaging unit 28, in accordance with the control unit 211, optically photographs the subject S using visible light to generate optical image data, which is then output to the control unit 211 and the like. The optical imaging unit 28 optically photographs the subject S to generate still images or motion (live images, etc.) optical image data.

[0043] The control unit 211 consists of a CPU, RAM, and other components. The CPU reads various programs stored in the memory unit 212 and loads them into the RAM. The CPU then works in cooperation with the loaded programs to execute various processes and control the various parts of the radiation generator 2 and the console 3.

[0044] The memory unit 212 is composed of non-volatile memory, an HDD, and the like. The memory unit 212 stores various data such as various programs executed by the control unit 211, parameters necessary for program execution, and files. The memory unit 212 stores a recommended equipment information display program for executing the recommended equipment information display process described later.

[0045] Upon receiving a shooting instruction signal from the control unit 211, the generator 213 applies a voltage to the tube 23 according to the preset shooting conditions and supplies a current to the tube 23 according to the shooting conditions.

[0046] The communications unit 214 consists of communications modules and the like. The communication unit 214 can send and receive various signals and data to and from the wirelessly connected FPD1 and external devices such as RIS40 via the communication network N.

[0047] Console 3 comprises a control unit, a storage unit, a communication unit, a display unit 31, an operation unit 32, and an audio output unit 33. The control unit, storage unit, and communication unit of Console 3 are also the control unit 211, storage unit 212, and communication unit 214 of the radiation generator 2, respectively. Alternatively, Console 3 may be configured to include a dedicated control unit, storage unit, and communication unit.

[0048] The display unit 31 is composed of an LCD (Liquid Crystal Display) or an EL (Electro-Luminescence) display, etc. The display unit 31 displays various information according to the display information input from the control unit 211.

[0049] The operation unit 32 includes, for example, a keyboard with various keys, a pointing device for inputting location information, and a touch panel integrally formed on the display screen of the display unit 31. The operation unit 32 receives operation input from the user and outputs the operation information to the control unit 211.

[0050] The audio output unit 33 is equipped with an amplifier, speaker, etc., and outputs audio according to the audio information input from the control unit 211.

[0051] <2. Operation of the radiography system> Next, the operation of the radiography system 100 will be explained with reference to Figure 3. Users such as radiographers go to a waiting area where the FPD1 and mobile radiography unit RC are located before going to the patient being examined at the examination site. Then, in the mobile radiography unit RC, the control unit 211 executes the recommended equipment information display process shown in Figure 3, according to the recommended equipment information display program stored in the memory unit 212.

[0052] The control unit 211 performs a recommended equipment information display process to determine recommended equipment information, which indicates the recommended equipment to be used for radiography to be performed at the next ward round. The control unit 211 then notifies the user of the determined recommended equipment information by displaying it on the display unit 31. In other words, the control unit 211 notifies the radiographer of information regarding the imaging equipment to be used at the destination, which is determined based on the examination information concerning the patient being radiographed using the mobile radiography unit RC. Here, the control unit 211 functions as a notification unit. In this case, the console 3 is the radiography image acquisition support device.

[0053] The imaging equipment includes FPD1, a grid that can be attached to and detached from FPD1, a fixing jig for securing the subject, and auxiliary equipment.

[0054] (Displaying recommended equipment information) First, the control unit 211 acquires inspection information, related information associated with the inspection information, and equipment status information, which is information regarding the status of the imaging equipment (step S1).

[0055] The examination information obtained in step S1 includes examination ID, examination date and time, requesting department, ward round location, imaging information, etc. The locations covered during these rounds are places where radiography is performed, such as wards, intensive care units, operating rooms, and general radiography rooms. The imaging information includes the imaging area, imaging direction, size and resolution of the FPD1 corresponding to the imaging, information on the type of imaging, irradiation conditions, dose indicators for this imaging, whether a grid is required, and the type of grid. Information regarding the type of photography in question includes still photography, motion photography, and fluoroscopic photography. Here, a series of images obtained through motion photography is called a motion image. Furthermore, each of the multiple images that make up a motion image is called a frame image. Furthermore, while motion photography includes video recording, it does not include still images taken while displaying video. Similarly, while motion images include video, they do not include images obtained by taking still images while displaying video. Furthermore, the irradiation conditions include mAs value, tube voltage, frame rate, and irradiation time.

[0056] The relevant information obtained in step S1 includes patient information, past imaging data, statistical information, etc. The patient information in question is information about the patient as a subject undergoing radiography. Specifically, the patient information includes the patient's patient ID, name, gender, pregnancy status, age, height, weight, medical precautions, medical history, location within the facility (such as a ward), and condition. The patient's condition refers to things like whether the patient has kyphosis, has difficulty lying on their side, or has tubes attached for intravenous drips, etc.

[0057] The past imaging information refers to imaging data from radiography performed in the past. Specifically, the past imaging information includes information on the imaging site, imaging direction, size and resolution of the FPD1 corresponding to the imaging, type of imaging, irradiation conditions, cropping size during past imaging, precautions during past imaging, presence or absence of a grid, type of grid, whether or not image processing was applied, and imaging location. The precautions taken during the previous filming included, for example, the number of camera operators who performed the previous filming. This image processing includes, for example, scattered radiation correction processing. The locations in question for imaging include, for example, hospital wards, intensive care units, operating rooms, and general radiography rooms.

[0058] The statistical information includes the frequency of using the combination of the mobile radiography unit (RC) and FPD1 in radiography, the frequency of using the combination of imaging information and FPD1 in radiography, the frequency of using the combination of patient cases and FPD1 in radiography, and the frequency of using the combination of radiographer information and fixation jigs or auxiliary devices in radiography. The radiographer information refers to information about the radiographer performing the radiography.

[0059] The equipment status information acquired in step S1 includes the location information of FPD1, the battery level information of FPD1, the type of FPD1, the location information of the mobile RC, the charging status information of the mobile RC, the number of FPD1s that can be stored in the mobile RC, the date of the last scan in the mobile RC, the interval between scans in the mobile RC, and the radiographer's information.

[0060] In step S1, for example, the control unit 211 acquires examination information and patient information from the RIS 40 via the communication unit 214 at predetermined intervals. Alternatively, the control unit 211 may acquire examination information and patient information from the RIS 40 via the communication unit 214 when the user inputs an instruction to update examination information via the operation unit 32.

[0061] Alternatively, the control unit 211 may acquire examination information and patient information as follows. Specifically, first, the control unit 211 receives patient information input from the user via the operation unit 32. Then, the control unit 211 transmits the received patient information to the RIS 40. The RIS 40 transmits examination information based on the received patient information to the mobile examination vehicle RC. Then, the control unit 211 receives the examination information from the RIS 40. Furthermore, if examination information is stored in the memory unit 212, the control unit 211 may acquire the examination information as follows. Specifically, the control unit 211 acquires the examination information from the memory unit 212 based on the patient information received as input via the operation unit 32.

[0062] Furthermore, if patient information, imaging information, past imaging information, statistical information, and equipment status information are stored in the memory unit 212, the control unit 211 will retrieve that information from the memory unit 212. Furthermore, if patient information, imaging information, past imaging information, statistical information, and equipment status information are stored in the memory of another radiography system, the control unit 211 will acquire that information from the other radiography system.

[0063] Furthermore, the control unit 211 may acquire equipment status information from other mobile medical units RC. Furthermore, the control unit 211 may acquire patient information, imaging information, and equipment status information from devices such as PACS, other examination equipment, or a bed system. Furthermore, the control unit 211 may acquire patient information, imaging information, and equipment status information based on the optical imaging unit 28. Furthermore, the control unit 211 may acquire, in addition to patient information, examination information and equipment status information through user input via the operation unit 32. The control unit 211 may also acquire patient information from a DICOM (Digital Image and Communications in Medicine) tag.

[0064] Next, the control unit 211 selects the target examination information to determine the recommended equipment information that indicates the recommended imaging equipment to be used for radiography to be performed at the next ward round (step S2). For example, the control unit 211 considers all examination information acquired from the RIS 40 in step S1 as the subject of determination. The examination information transmitted from the RIS 40 to the mobile examination unit RC is the examination information for the mobile examination images to be taken by the mobile examination unit RC. Therefore, in this case, the control unit 211 considers the examination information for the mobile examination images to be taken by its own mobile examination unit RC as the subject of determination.

[0065] Alternatively, the control unit 211 may select the examination information to be determined as follows. Specifically, first, the control unit 211 displays a list of candidate examination information on the display unit 31. These candidate examination information includes examination information from mobile imaging taken by the mobile imaging unit RC, and examination information from mobile imaging taken by other mobile imaging units RC. The control unit 211 then accepts the user's selection input of the examination information to be determined from the displayed examination information via the operation unit 32. The control unit 211 then sets the examination information selected by the user as the examination information to be determined.

[0066] Figure 4 shows an example of the display screen 311 displayed on the display unit 31. The control unit 211 displays a list 311a on the display screen 311 containing candidate examination information and related information for that examination information. In the list 311a, the control unit 211 displays, for example, patient ID, patient name, imaging site, scheduled date and time of imaging, size of the FPD1 corresponding to the imaging, imaging conditions, etc. The imaging conditions include tube voltage, mAs value, S value, etc. The S value is the sensitivity, which corresponds to the radiation dose during radiography.

[0067] The control unit 211 receives selection input from the user via the operation unit 32, which is displayed in the list 311a. The control unit 211 may also display checkboxes or the like in the list 311a to indicate user selection input. Furthermore, the control unit 211 may provide a tab on the display screen 311 that displays only the examination information for mobile imaging. Furthermore, the control unit 211 may display the inspection information selected by the user on a separate tab within the display screen 311, or on a screen separate from the display screen 311, such as a dialog box. Then, when the control unit 211 receives input from the user to press the equipment selection button 311b on the display screen 311 while the inspection information to be determined is selected, it proceeds to step S3.

[0068] Alternatively, the control unit 211 may select the inspection information to be determined as follows. Specifically, the control unit 211 selects the inspection information to be determined based on selection criteria that are set in advance for each facility or each user. These selection criteria include, for example, examination information that has not yet been recorded, examination information that targets patients in a specific ward, and examination information that targets the same patients who were recorded in the focused prescribed examination.

[0069] Furthermore, the control unit 211 may select examination information relating to one subject as the target for determination, or it may select examination information relating to multiple subjects as the target for determination.

[0070] Alternatively, in step S2, the control unit 211 may select the target for determination by limiting it to examination information that is a mobile imaging scan. Alternatively, in step S2, the control unit 211 may select a target for determination from the examination information, which includes general radiography, dynamic radiography, and ward round radiography.

[0071] Next, the control unit 211 determines the recommended equipment information corresponding to the inspection information selected in step S2, based on the inspection information, related information, and equipment status information (step S3).

[0072] The recommended equipment information for this embodiment includes the recommended size of the FPD1. The following describes how to determine the recommended size of the FPD1. For example, the control unit 211 determines the largest size of the FPD1 from among the sizes of the FPD1 based on the imaging information included in the multiple inspection information to be determined as the recommended size of the FPD1. Furthermore, the control unit 211 determines the recommended order of FPD1 sizes based on a preset priority. For example, the control unit 211 sets a recommended order for the FPD1 size based on the imaging information included in the examination information to be determined, and for the FPD1 size used when imaging the same patient corresponding to the examination information in the past. Furthermore, the control unit 211 estimates the patient's physique from patient information obtained from radiography during a predetermined period in the past, corresponding to the examination information to be determined. The control unit 211 then determines the size of the FPD1 corresponding to the estimated physique as the recommended size of the FPD1. This predetermined period is, for example, one year. Furthermore, the control unit 211 determines the recommended size of the FPD1 based on the patient's height and weight, which are related to the examination information being determined.

[0073] Furthermore, the case where the size of the FPD1 included in the inspection information to be determined does not match the size of the FPD1 included in the past imaging information related to that inspection information will be explained. In this case, the control unit 211 determines the size of the FPD1 included in the past imaging information as the recommended size of the FPD1. Furthermore, the control unit 211 determines the recommended size of FPD1 based on the trimming size included in past imaging information related to the inspection information to be determined. Specifically, the control unit 211 determines the recommended size of FPD1 to be a size that can accommodate the trimming size from past radiographic imaging. Furthermore, if the radiographer's gender, as indicated in the radiographer information, is female, the control unit 211 determines a relatively small FPD1 size as the recommended FPD1 size.

[0074] The recommended equipment information for this embodiment includes the number of recommended FPD1 size variations. The method for determining the specific recommended number of FPD1 size variations is described below. For example, the control unit 211 determines the recommended number of FPD1 sizes based on the size of the FPD storage unit 26. In this case, the equipment status information includes the size of the FPD storage unit 26.

[0075] Furthermore, the recommended equipment information in this embodiment includes information on the type of recommended FPD1. The method for determining the specific recommended FPD1 type information is described below. For example, if the control unit 211 determines that the type of FPD1 capable of dynamic imaging is the recommended type of FPD1 when the information regarding the type of imaging included in the inspection information to be determined is dynamic imaging. Furthermore, if the irradiation conditions included in the inspection information to be determined include frame rate information, the control unit 211 determines that the type of imaging is dynamic imaging. Then, the control unit 211 determines the type of FPD1 capable of dynamic imaging as the recommended type of FPD1. Furthermore, if the dose index value included in the inspection information to be determined is greater than a predetermined threshold, the control unit 211 determines that the type of imaging is dynamic imaging. The control unit 211 then determines the type of FPD1 capable of dynamic imaging as the recommended type of FPD1.

[0076] Furthermore, if the resolution of the imaging information included in the inspection information to be determined is high, the control unit 211 determines the type of FPD1 capable of imaging with a high reading resolution as the recommended type of FPD1. Furthermore, the control unit 211 determines the case to be imaged based on the requesting department and imaging site included in the examination information to be determined. The control unit 211 then determines the type of FPD1 that can image at a resolution corresponding to the determination result as the recommended type of FPD1.

[0077] Furthermore, the control unit 211 determines the type of FPD1 as the recommended type of FPD1 based on the imaging site included in past imaging information related to the examination information to be determined. Specifically, the control unit 211 determines the type of FPD1 used in past radiography that imaged the same site as the current imaging site as the recommended type of FPD1. Furthermore, the control unit 211 determines the type of FPD1 as the recommended type of FPD1 based on information about the type of imaging included in past imaging information related to the inspection information to be determined. Specifically, the control unit 211 determines the type of FPD1 used in past radiography of the same type as the current imaging type as the recommended type of FPD1. Furthermore, the control unit 211 determines the type of FPD1 as the recommended type of FPD1 based on the irradiation conditions included in past imaging information related to the inspection information being determined. Specifically, the control unit 211 determines the type of FPD1 used in past radiography with the same irradiation conditions as the current irradiation conditions as the recommended type of FPD1. Furthermore, the control unit 211 determines the type of FPD1 as the recommended type of FPD1 based on the precautions taken during past imaging included in the past imaging information related to the inspection information to be determined.

[0078] Furthermore, the case where the resolution included in the inspection information to be determined does not match the resolution included in the past imaging information related to that inspection information will be explained. In this case, the control unit 211 determines the type of FPD1 that can capture images at the resolution included in the past imaging information as the recommended type of FPD1. Furthermore, the control unit 211 determines whether the type of FPD1 determined as described above matches the type of FPD1 included in the equipment status information. If the types of FPD1 match, the control unit 211 may then use the determined type of FPD1 as the recommended type of FPD1.

[0079] Furthermore, the recommended equipment information in this embodiment includes identification information for the recommended FPD1. The following describes the specific recommended method for determining the identification information of FPD1. For example, let's consider the case where there are multiple FPD1s with the recommended size. In this case, the control unit 211 determines, based on statistical information, that the FPD1 that is frequently used for imaging information included in the inspection information to be determined is the recommended FPD1. Furthermore, the control unit 211 determines, based on statistical information, that the FPD1 that is frequently used in combination with the mobile medical unit RC is the recommended FPD1. Furthermore, the control unit 211 determines, based on statistical information, the FPD1 that is frequently used in combination with the patient's case corresponding to the examination information being determined as the recommended FPD1.

[0080] Furthermore, the control unit 211 decides to exclude FPD1s from the recommended FPD1s if their location, as included in the equipment status information, is more than a predetermined threshold away from the ward round destination included in the examination information to be determined. Furthermore, the control unit 211 decides to exclude FPD1s whose battery level included in the equipment status information is below a predetermined threshold from the recommended FPD1s. Furthermore, the control unit 211 decides to exclude from the recommended FPD1 any FPD1 whose battery level, as included in the equipment status information, is below the level required to capture the inspection information to be determined.

[0081] Furthermore, the recommended equipment information in this embodiment includes information on the recommended grid type. The method for determining the specific recommended grid type information is described below. For example, the control unit 211 determines the type of grid corresponding to the size of the FPD1 based on the imaging information included in the inspection information to be determined as the recommended type of grid. Furthermore, the control unit 211 determines the type of grid recommended based on the imaging area included in the examination information to be determined. For example, if the imaging area is the chest, the control unit 211 determines a grid with a grid ratio of 10:1 as the recommended grid. Similarly, if the imaging area is the abdomen, the control unit 211 determines a grid with a grid ratio of 8:1 as the recommended grid.

[0082] Furthermore, if the control unit 211 determines that the type of imaging included in the inspection information to be determined is dynamic imaging, it will select a grid for dynamic imaging as the recommended grid. Furthermore, the control unit 211 determines the type of grid corresponding to the ward round destination included in the examination information to be determined as the recommended type of grid. For example, if the ward round destination is an operating room or emergency ward, the control unit 211 determines the type of grid corresponding to the FPD1 that can be used on the operating table or custom-made emergency bed as the recommended type of grid. Furthermore, the control unit 211 determines the type of grid based on past imaging information related to the inspection information to be determined as the recommended grid type. For example, consider the case where scattered radiation correction processing was used in the previous radiography and the image was gridless. In this case, the control unit 211 determines that the recommended grid type is gridless.

[0083] Furthermore, the recommended equipment information in this embodiment includes information on the types of recommended fixing jigs and auxiliary tools. The method for determining specific recommended types of fixing jigs and auxiliary devices is described below. For example, the control unit 211 determines the type of fixing jig and auxiliary device corresponding to the imaging site included in the examination information to be determined as the recommended type of fixing jig and auxiliary device. For example, consider a case where the imaging site is the side of the chest, and it is necessary to move and fix the subject during imaging. In this case, the control unit 211 determines the type of fixing jig and auxiliary device necessary for the movement and fixing of the subject as the recommended type of fixing jig and auxiliary device.

[0084] Furthermore, the control unit 211 determines the types of fixing jigs and auxiliary devices as recommended types based on the imaging site included in past imaging information related to the inspection information being determined. Specifically, the control unit 211 determines the types of fixing jigs and auxiliary devices as recommended types based on the types of fixing jigs and auxiliary devices used in past radiography imaging of the same site as the current imaging site. Furthermore, the control unit 211 determines the types of fixing jigs and auxiliary devices as recommended types based on the imaging direction included in past imaging information related to the inspection information to be determined. Specifically, the control unit 211 determines the types of fixing jigs and auxiliary devices used in past radiographic imaging taken in the same direction as the current imaging direction as recommended types of fixing jigs and auxiliary devices. Furthermore, the control unit 211 determines the type of fixing jig and auxiliary device as the recommended type of fixing jig and auxiliary device, based on the information regarding the type of imaging included in past imaging information related to the inspection information to be determined. Specifically, the control unit 211 determines the same type as the current imaging type. The types of fixation jigs and auxiliary devices used in past radiography will be determined as the recommended types of fixation jigs and auxiliary devices.

[0085] Furthermore, the control unit 211 determines the types of fixing jigs and auxiliary devices as recommended types based on the irradiation conditions included in past imaging information related to the inspection information being determined. Specifically, the control unit 211 determines the types of fixing jigs and auxiliary devices used in past radiography with the same irradiation conditions as the current irradiation conditions as recommended types of fixing jigs and auxiliary devices. Furthermore, the control unit 211 determines the types of fixing jigs and auxiliary devices as recommended types based on precautions taken during past imaging included in past imaging information related to the inspection information to be determined. Furthermore, the control unit 211 determines the types of fixing jigs and auxiliary devices as recommended types based on the imaging locations included in past imaging information related to the examination information being determined. Specifically, the control unit 211 determines the types of fixing jigs and auxiliary devices as recommended types based on the types of fixing jigs and auxiliary devices used in past radiography at the same location as the current ward rounds.

[0086] Furthermore, the control unit 211 determines the type of fixation jig and auxiliary device as the recommended type of fixation jig and auxiliary device, based on patient information and technician information related to the examination information to be determined. For example, the control unit 211 determines the type of fixation jig and auxiliary device according to the combination of the patient's physique and the technician's gender. Specifically, let's explain the case where the patient's physique is greater than a predetermined threshold, the technician is female, and the technician's power deficiency is expected. In this case, the control unit 211 determines that a fixation jig is necessary as the recommended type of fixation jig and auxiliary device. Furthermore, the control unit 211 determines the types of fixing jigs and auxiliary devices as recommended types based on the information regarding the type of imaging included in the examination information to be determined. For example, if the information regarding the type of imaging is still imaging, the control unit 211 determines that fixing jigs for fixing the subject are the recommended types of fixing jigs and auxiliary devices. Also, if the information regarding the type of imaging is dynamic imaging, the control unit 211 determines that auxiliary devices for assisting the moving parts of the subject and fixing jigs for fixing the parts that do not move are the recommended types of fixing jigs and auxiliary devices.

[0087] Furthermore, the control unit 211 determines the type of fixation device and assistive device as the recommended type, based on the medical precautions related to the examination information being determined and the patient's location within the facility. For example, consider a case where the medical precaution is kyphosis and the patient's location within the facility is a ward using a bed that does not support reclining. In this case, the control unit 211 determines that a cushion or similar device to be inserted into the patient's lower back when the imaging position is seated is the recommended type of fixation device and assistive device. Furthermore, the control unit 211 determines the type of fixation device and support device as the recommended type of fixation device and support device, based on the patient's pregnancy status related to the examination information being determined. For example, if the patient is pregnant and there are limitations on the postures she can assume, the control unit 211 determines a cushion or the like to be inserted around the patient's waist as the recommended type of fixation device and support device. Furthermore, the control unit 211 determines the type of fixation fixture and assistive device based on the patient's age related to the examination information being determined, as the recommended type of fixation fixture and assistive device. For example, if the patient's age is above a predetermined threshold, the control unit 211 determines that an assistive device is necessary as the recommended type of fixation fixture and assistive device.

[0088] Furthermore, the control unit 211 determines the type of fixation device and assistive device recommended based on the patient's medical history related to the examination information being determined. For example, based on the patient's medical history, the control unit 211 determines whether the patient is bedridden, whether the patient has tubes attached, whether there are any positions the patient cannot assume, etc. Then, the control unit 211 determines the type of fixation device and assistive device recommended based on the results of this determination. Specifically, let's explain a case where the patient's medical history includes a fracture of the ribs in the lung field, and the patient cannot assume the position required for a lateral chest X-ray while lying in bed. In this case, the control unit 211 determines that an assistive device to support the patient is necessary as the recommended type of fixation device and assistive device.

[0089] Furthermore, the control unit 211 determines whether or not fixing jigs and assistive devices are necessary based on the imaging direction included in the examination information to be determined, and the patient's height and weight related to the examination information. The control unit 211 then determines this result as information on the type of fixing jig and assistive device recommended. Furthermore, based on statistical information, the control unit 211 determines the types of fixation jigs and auxiliary devices that are frequently used in combination with the ward round destination, imaging information, and imaging technician information included in the examination information to be determined as the recommended types of fixation jigs and auxiliary devices.

[0090] Furthermore, the recommended equipment information in this embodiment includes recommended support personnel information. The following explains how to determine the specific recommended support personnel information. For example, the control unit 211 determines recommended support personnel information based on patient information and technician information related to the examination information being determined. For example, the control unit 211 makes this determination based on the combination of the patient's physique and the technician's gender. Specifically, consider a case where the patient's physique is greater than a predetermined threshold, the technician is female, and the technician is expected to have insufficient power. In this case, the control unit 211 determines that support personnel are needed as recommended support personnel information.

[0091] The control unit 211 may also determine recommended equipment information by combining the above determination methods. Furthermore, the details of the above determination method may be configured to be changeable for each user or facility. Furthermore, the control unit 211 may determine recommended equipment information based on the ON / OFF information of the FPD1's power, the correspondence information (registration information) between the console 3 and the FPD1, and information on whether the FPD1 is in use or not.

[0092] As described above, the control unit 211 determines recommended equipment information based on examination information regarding the patient undergoing radiography using the mobile radiography unit RC. In other words, the radiography equipment used by the radiographer at the destination is determined based on examination information regarding the patient undergoing radiography using the mobile radiography device. Furthermore, the control unit 211 determines recommended equipment information based on a single set of examination information regarding a patient undergoing radiography using the mobile examination unit RC. In other words, the radiography equipment used by the radiographer at the destination is determined based on a single set of examination information. Furthermore, the control unit 211 determines recommended equipment information based on multiple examination data regarding the patient undergoing radiography using the mobile radiography unit RC. In other words, the radiography equipment used by the radiographer at the destination is determined based on multiple examination data. Furthermore, the control unit 211 determines recommended equipment information based on examination information and related information concerning the patient undergoing radiography using the mobile RC. In other words, the radiography equipment to be used by the radiographer at the destination is determined based on the examination information concerning the patient and related information concerning that examination. Furthermore, the control unit 211 determines recommended equipment information based on examination information and equipment status information regarding the patient undergoing radiography using the mobile RC. In other words, the radiography equipment to be used by the radiographer at the destination is determined based on examination information and information regarding the status of the radiography equipment concerning the patient.

[0093] Next, the control unit 211 displays the recommended equipment information determined in step S3 on the display unit 31 (step S4), and terminates this process. Step S4 is the notification step.

[0094] Figure 5 shows the display screen 312 that displays recommended equipment information. In the example shown in Figure 5, the control unit 211 displays all the information related to the examination of a single patient on the display screen 312. The vertical axis of the display screen 312 represents the inspection type, and the horizontal axis represents the time axis. In other words, the control unit 211 displays information about the inspection in a timeline format for each inspection type on the display screen 312.

[0095] Furthermore, the control unit 211 may use time units instead of date units as shown in Figure 5 for the horizontal axis of the display screen 312. Furthermore, the control unit 211 may display information about examinations performed on a day, rather than information about examinations performed on a single patient, on the display screen 312.

[0096] The control unit 211 displays, for example, a thumbnail image of the radiographic image taken during the inspection, such as thumbnail image 312a, for the inspection that has already been taken. Furthermore, the control unit 211 displays an icon 312b indicating the recommended equipment determined in step S3 for the inspection to be performed.

[0097] Furthermore, when the control unit 211 receives a click input from the user of the icon 312b via the operation unit 32, it displays the recommended equipment information screen 313 shown in Figure 6 on the display screen 312. In the example shown in Figure 6, the control unit 211 displays the recommended equipment information on the recommended equipment information screen 313, including the size of the FPD1, the grid type, and whether or not a fixing jig is required and its type.

[0098] Note that the display of recommended equipment information on the recommended equipment information screen 313 is not limited to the example shown in Figure 6. For example, let's consider a case where the size of the FPD1 included in the inspection information to be determined does not match the size of the FPD1 included in the past imaging information related to that inspection information. In this case, as described above, the control unit 211 determines in step S3 that the size of the FPD1 included in the past imaging information is the recommended size of the FPD1. In this case, the control unit 211 may display on the recommended equipment information screen 313 the reason why the size of the FPD1 was used in past shooting.

[0099] Furthermore, the case where the resolution included in the inspection information to be determined does not match the resolution included in the past imaging information related to the inspection information will be explained. In this case, the control unit 211 determines in step S3 that the type of FPD1 capable of imaging at the resolution included in the past imaging information is the recommended type of FPD1. In this case, the control unit 211 may display on the recommended equipment information screen 313 the reason why the FPD1 type was used in past shooting.

[0100] Furthermore, the control unit 211 may display on the recommended equipment information screen 313 any precautions taken during past shootings that are included in the past shooting information related to the inspection information to be determined. Furthermore, the control unit 211 may display on the recommended equipment information screen 313 an FPD1, fixing jig, or auxiliary device corresponding to the precautions taken during past imaging included in the past imaging information related to the inspection information to be determined.

[0101] Furthermore, the control unit 211 identifies the recommended FPD1 on the recommended equipment information screen 313. The following display options may be used when displaying information: Specifically, the control unit 211 may further display the recommended location information of the FPD1. Furthermore, if the recommended battery level of the FPD1 is below a predetermined threshold, the control unit 211 may also display battery level information for the FPD1.

[0102] Furthermore, when the control unit 211 displays recommended support personnel information as recommended equipment information on the recommended equipment information screen 313, it may also display the following: For example, consider a scenario where the patient's physique exceeds a predetermined threshold, the radiographer is female, and insufficient power from the radiographer is anticipated. In this case, the control unit 211 may display a message suggesting that the imaging be performed by two radiographers.

[0103] Furthermore, in the example shown in Figure 6, the control unit 211 displays one type each of the recommended FPD1 size, grid type, and fixing jig type as recommended equipment information, but is not limited to this. The control unit 211 may display multiple types of recommended imaging equipment as recommended equipment information. When the control unit 211 displays multiple types of recommended imaging equipment, it is preferable to display them along with their recommendation ranking.

[0104] Figure 7 shows another example of a display screen 314 that shows recommended equipment information. In the example shown in Figure 7, the vertical axis of the display screen 314 is the time axis, and the horizontal axis is the date. The control unit 211 displays information related to the inspection in a timeline format on the display screen 314.

[0105] The control unit 211 displays an icon 314a indicating the recommended equipment determined in step S3 for the inspection to be performed. Furthermore, when the control unit 211 receives a click input from the user of the icon 314a via the operation unit 32, it displays a recommended equipment information screen on the display screen 314 that is similar to the recommended equipment information screen 313 shown in Figure 6. In other words, the control unit 211, acting as a notification unit, notifies the user (photographer) by displaying information (recommended equipment information) about the photographic equipment to be used at the destination, based on a predetermined operation performed by the user (operator), as shown in Figures 5 to 7. In this case, the predetermined operation is a click input by the user on the icons 312b and 314a that indicate the photographic equipment.

[0106] Figure 8 shows another example of displaying recommended equipment information. The example shown in Figure 8 is when, in step S2 above, the control unit 211 receives a user's selection of multiple inspection information items to be determined from the inspection information displayed in the list 311a. In this case, in step S3, when the control unit 211 receives a click input from the equipment determination button 311b after the selection operation by the user, it determines the recommended equipment information corresponding to the selected multiple inspection information. Then, in step S4, the control unit 211 displays a recommended equipment information screen 313 on the display screen 311, as shown in Figure 8, which displays the recommended equipment information determined in step S3.

[0107] In other words, the control unit 211, acting as a notification unit, notifies the user (photographer) by displaying information (recommended equipment information) about the photographic equipment to be used at the destination, based on a predetermined operation performed by the user (operator). In this case, the prescribed operation is the user's designation of the object to be radiographically scanned for inspection. Here, the user's designation of the object to be radiographically scanned for inspection means the user's selection of the inspection information to be determined.

[0108] Furthermore, the types, display formats, and tables of recommended equipment information displayed in step S4 are also important. Currently, the system may be configured to allow for configuration changes on a facility-by-facility basis. Furthermore, when the control unit 211 receives a click input from the user of the OK button 313a (see Figure 8) provided on the recommended equipment information screen 313, it performs the following processing. Specifically, the control unit 211 changes the size of the FPD1 included in the inspection information selected as the target of determination to the size of the FPD1 as the recommended equipment information.

[0109] Furthermore, in the example shown in Figure 8, the control unit 211 performs steps S3 and S4 when it receives a click input from the user of the equipment selection button 311b, but it is not limited to this. The control unit 211 may also perform steps S3 and S4 when it receives a press operation from the user of the inspection start button (not shown). The inspection start button is provided, for example, on the main unit 21 of the generator.

[0110] Furthermore, we will explain the case in which the control unit 211 selects all the inspection information displayed in the list 311a as the target for determination in step S2. In this case, the control unit 211 performs steps S3 and S4 without accepting a user's operation to select inspection information. Then, in step S4, the control unit 211 provides an area on the display screen 311 for displaying the recommended equipment information determined in step S3, and displays the recommended equipment information. In other words, the control unit 211, acting as a notification unit, notifies the user (photographer) by displaying information (recommended equipment information) regarding the imaging equipment to be used at the destination, based on a predetermined operation performed by the user (operator). In this case, the predetermined operation is either an instruction by the user in step S1 to update the examination information, or input of patient information, which is related information to the examination information, by the user in step S1.

[0111] Figure 9 shows another example of displaying recommended equipment information. The example shown in Figure 9 is similar to the example shown in Figure 8, where in step S2, the control unit 211 accepts multiple selections of inspection information to be determined by the user from the inspection information displayed in the list 311a. In step S4, the control unit 211 displays the recommended equipment information determined in step S3 in the display area 311c of the display screen 311, as shown in Figure 9.

[0112] Figure 10 shows another example of displaying recommended equipment information. The example shown in Figure 10 is an example of a display when the recommended equipment determined by the control unit 211 in step S3 may not be available. In this case, the control unit 211 displays a warning screen 315 on the display screen 311 in step S4. For example, in step S3, the control unit 211 determines the recommended size of FPD1 to be "17 x 17", but the power to an FPD1 of that size is currently OFF. In this case, the control unit 211 displays a message to that effect on the warning screen 315. The control unit 211 also displays a message on the warning screen 315 prompting the user to resolve the reason why the recommended equipment cannot be used. In the example shown in Figure 10, the control unit 211 displays the message, "Please make the equipment selection again after you are ready," prompting the user to turn on the power to the recommended FPD1.

[0113] Furthermore, the control unit 211 may make the display mode of the warning screen 315 different from that of the recommended equipment information screen 313. For example, the control unit 211 may change the color or font of the warning screen 315 from that of the recommended equipment information screen 313, or add marks or other symbols to the warning screen 315 for emphasis. This makes it easy for users to recognize that the recommended equipment may not be available.

[0114] The control unit 211 may display the warning screen 315 in step S4 in the following cases. Specifically, this refers to the case where the recommended FPD1 determined in step S3 is not associated with console 3. In other words, it refers to the case where the recommended FPD1 is not registered in console 3. In this case, the control unit 211 may display information about the FPD1 with the second recommendation rank on the warning screen 315. Another case is when the recommended FPD1 determined in step S3 does not match the FPD stored in the FPD storage compartment 26 of the radiation generator 2. In other words, the control unit 211, acting as a notification unit, notifies the user if there is a mismatch between the FPD stored in the FPD storage unit 26 and the FPD determined to be the photographic equipment to be used by the photographer at their destination.

[0115] Furthermore, the control unit 211 may display the warning screen 315 in step S4 in the following cases: Specifically, this refers to the case where the recommended battery level of FPD1 determined in step S3 is below a predetermined threshold. Another case is when the recommended FPD1 size determined in step S3 differs from the FPD1 size corresponding to the imaging included in the examination information being determined. This also applies if the recommended FPD1 determined in step S3 is already in use for another examination. Furthermore, this applies if the recommended location of FPD1 determined in step S3 is at a location more than a predetermined distance away from the mobile medical unit RC.

[0116] Figure 11 shows another example of displaying recommended equipment information. As shown in Figure 11, the control unit 211 may also include a reason display button 313b on the recommended equipment information screen 313, which displays recommended equipment information. When the control unit 211 receives a click input from the user of the reason display button 313b via the operation unit 32, it displays the reason screen 316 shown in Figure 12. The control unit 211 displays the reason for determining the recommended equipment information in step S3 as the recommendation reason on the reason screen 316. By displaying the reasons for the recommendation in this way, it is possible to improve user satisfaction and educational value, such as that of camera operators.

[0117] Furthermore, the control unit 211 may provide a scroll function on the recommended equipment information screen 313 and display the reason for the recommendation at the bottom of the recommended equipment information. Furthermore, the control unit 211 may display the recommendation reasons for each piece of imaging equipment, or it may display them all together. The control unit 211 may also display alternative photographic equipment as alternatives to the recommended equipment, along with the reasons for the recommendation. Furthermore, the control unit 211 may display essential recommendation reasons in a different color or font from other recommendation reasons, or highlight them by adding marks or other symbols. The essential recommendation reasons are described below. For example, if the inspection information to be determined includes the fact that the imaging is motion imaging, the control unit 211 will always determine that an FPD1 capable of motion imaging is the recommended FPD1. In this case, the control unit 211 will display as an essential recommendation reason that an FPD1 capable of motion imaging has been selected because the imaging is motion imaging.

[0118] After the recommended equipment information display process is completed, the user, such as a radiographer, goes from the waiting area to the location where the patient to be examined is located, along with the radiography equipment indicated in the recommended equipment information displayed during the process. The user then begins radiography of the patient using the specified equipment.

[0119] <3. Others> The present invention has been described above based on the above embodiments, but the description in the above embodiments is a preferred example of the radiography system according to the present invention and is not limited thereto. For example, in the recommended equipment information display processing step S4, the control unit 211 may display recommended equipment information for each predetermined unit. The predetermined unit may be an imaging unit, an examination unit, a ward round unit, a ward unit, a schedule time frame unit, etc. When displaying recommended equipment information per shooting unit, the control unit 211 may display the recommended equipment information as a list. Furthermore, the control unit 211 may display recommended equipment information using symbols, or notify users via voice from the voice output unit 33, in addition to displaying it using text and icons.

[0120] Furthermore, in the recommended equipment information display processing step S4, the control unit 211 may transmit the recommended equipment information determined in step S3 to another device via the communication unit 214. This other device may be a console equipped with a radiography system for general radiography, a mobile radiography unit (RC), etc. When this other device receives the recommended equipment information, it displays the recommended equipment information on its own display unit. In this case, the control unit 211 may transmit only the recommended equipment information corresponding to the inspection performed by the other device to the other device.

[0121] Furthermore, the recommended photographic equipment may be determined as follows: In the recommended equipment information display processing step S4, the case in which the control unit 211 displays multiple recommended FPDs will be described. In this case, the user, such as a radiographer, takes multiple recommended FPDs to the site of their rounds. The user then has the control unit 211 execute the recommended equipment information display process again at the site of the rounds, and in step S1, inputs additional information based on the situation at the site of the rounds. Then, in step S4, the user decides which of the multiple FPDs they brought to use for imaging based on the recommended equipment information displayed.

[0122] <4. Variation> Next, a modified example of the present invention will be described. The radiographic image acquisition support device of the present invention may be applied to a console in a radiographic system for general radiography. Figure 13 shows a schematic configuration diagram of the radiography system 100A for general radiography in this modified example.

[0123] As shown in Figure 13, the radiography system 100A comprises a radiography device 1A, a radiation generator 2A, a console 3A, and a mobile medical unit RC. The radiography apparatus 1A, the radiation generator 2A, and the console 3A can communicate with each other, for example, via a communication network NA.

[0124] The radiography device 1A generates radiographic image data corresponding to the radiation R emitted from the radiation generator 2A.

[0125] The radiation generator 2A comprises a generator 21A, an irradiation instruction switch 22A, and a light tube 23A. Based on the operation of the irradiation instruction switch 22A, the generator 21A applies a voltage to the tube 23A according to the preset shooting conditions. When a voltage is applied to the tube 23A from the generator 21A, it generates radiation R (e.g., X-rays) in a dose corresponding to the applied voltage.

[0126] Console 3A can set imaging conditions for at least one of the radiography apparatus 1A and the radiation generator 2A. Furthermore, console 3A can acquire the radiographic image data generated by radiography device 1A, save it to itself, or transmit it to other external devices (such as PACS).

[0127] Furthermore, the console 3A includes a control unit 31A, a storage unit 32A, a communication unit 33A, a display unit 34A, an operation unit 35A, and an audio output unit 36A. The memory unit 32A, communication unit 33A, display unit 34A, operation unit 35A, and audio output unit 36A have the same configuration as the memory unit 212, communication unit 214, display unit 31, operation unit 32, and audio output unit 33, respectively.

[0128] The control unit 31A consists of a CPU, RAM, and other components. The CPU reads various programs stored in the memory unit 32A and loads them into the RAM. The CPU then works in cooperation with the loaded programs to execute various processes and control the various parts of the console 3A.

[0129] In this modified example, we describe a case where console 3A, which is a general radiography console, performs recommended equipment information display processing. In this case, the control unit 31A notifies the radiographer of information regarding the radiography equipment to be used at the destination, which is determined based on the examination information concerning the patient being radiographed by the mobile radiography unit RC. Here, the control unit 31A functions as a notification unit. In this case, console 3A is a radiography image acquisition support device. Furthermore, the radiography equipment in this case includes the mobile radiography unit RC that performs mobile radiography.

[0130] In the recommended equipment information display processing step S3, the control unit 31A determines the recommended equipment information corresponding to the inspection information selected in step S2, similar to the embodiment described above. The control unit 31A determines the recommended equipment information based on the inspection information, related information, and equipment status information.

[0131] The recommended equipment information for this modified example also includes information on the type of recommended mobile RC (Rescue Carrier). It is preferable that the recommended mobile radiography unit (RC) type information be provided to the user, such as a radiographer, before they select the RC at their waiting area. Therefore, in this case, the control unit 31A of the general radiography console 3A performs the recommended equipment information display process. The method by which the control unit 31A determines the recommended mobile radiography unit (RC) type is described below. For example, the control unit 31A determines the type of mobile RC (radio-controlled vehicle) as the recommended type of mobile RC based on the information regarding the type of imaging included in the examination information to be determined. For example, if the information regarding the type of imaging is dynamic imaging, the control unit 31A determines the type of mobile RC capable of dynamic imaging as the recommended type of mobile RC.

[0132] Furthermore, the recommended equipment information for this modified example includes identification information for the recommended mobile RC (Remote Control) unit. It is preferable that the identification information of the recommended mobile radiography unit (RC) is provided to the user, such as a radiographer, before they select the RC at the waiting area. Therefore, in this case, the control unit 31A of the general radiography console 3A performs the recommended equipment information display process. The method by which the control unit 31A determines the identification information of the recommended mobile radiography unit (RC) is described below. For example, the control unit 31A determines the recommended mobile medical unit RC based on patient information and equipment status information related to the examination information to be determined. For example, the control unit 31A determines the recommended mobile medical unit RC to be the mobile medical unit RC whose location is the subject's residence within the facility. Furthermore, the control unit 31A determines the recommended mobile medical unit RC based on the mobile medical unit RC and the equipment status information included in the examination information to be determined. For example, the control unit 31A determines the recommended mobile medical unit RC to be the mobile medical unit RC whose location is relatively close to the mobile medical unit RC.

[0133] Furthermore, the control unit 31A decides to exclude from the recommended mobile medical unit RC any mobile medical unit RC whose location, as included in the equipment status information, is more than a predetermined threshold away from the medical unit destination included in the examination information to be determined. Furthermore, the control unit 31A decides to exclude from the recommended mobile medical vehicle RCs any mobile medical vehicle RCs whose charge status included in the equipment status information is below a predetermined threshold. Furthermore, the control unit 31A decides to exclude from the recommended mobile examination vehicles RC if the charge status of the mobile examination vehicle RC included in the equipment status information is less than the charge level required to perform imaging in the examination information being determined.

[0134] Next, in the recommended equipment information display processing step S4, the control unit 31A displays the recommended equipment information determined in step S3 on the display unit 34A, similar to the embodiment described above.

[0135] The control unit 31A may display the following information when displaying the identification information of the recommended medical cart RC on the recommended equipment information screen 313 displayed on the display unit 34A. Specifically, the control unit 31A may further display the location information of the recommended mobile medical vehicle RC. Furthermore, if the charge status of the recommended mobile medical vehicle RC is below a predetermined threshold, the control unit 31A may also display information about the charge status of the mobile medical vehicle RC.

[0136] Furthermore, the control unit 31A may display a warning screen 315 on the display unit 34A in step S4 in the following cases. Specifically, this is when the recommended mobile examination cart RC determined in step S3 is being used for another examination.

[0137] In step S4, the control unit 31A may transmit the recommended equipment information determined in step S3 to the console 3 of the mobile medical unit RC. When the control unit 211 of the console 3 receives the recommended equipment information, it displays the recommended equipment information on the display unit 31. In this case, the control unit 211 functions as a notification unit.

[0138] Furthermore, in the above embodiments and modified examples, the recommended equipment information display processing may be performed on an external device such as the RIS40 or a terminal device such as a PC used by the user. In this case, the external device may determine the recommended equipment information and transmit the determined recommended equipment information to the console 3 of the mobile medical unit RC.

[0139] Furthermore, the display items and display methods for recommended equipment information may be set for each device that displays the recommended equipment information. For example, the console 3A of the radiography system 100A for general radiography displays information about the mobile radiography unit as recommended equipment information. On the other hand, the mobile radiography unit RC does not display information about the mobile radiography unit RC as recommended equipment information.

[0140] <5.

Therefore, users can appropriately prepare imaging equipment suitable for the examination information and equipment status information before going to the patient's location for rounds.

[0149] Furthermore, in the radiation image acquisition support device of this embodiment, the notification unit (control unit 211, control unit 31A) notifies the user of information regarding the imaging equipment based on a predetermined operation. Therefore, when the user performs a predetermined operation, the system can notify the user of the appropriate imaging equipment for the location being examined.

[0150] Furthermore, in the radiation image acquisition support device of this embodiment, the predetermined operation is one of the following: the user designating the object to be radiographed for examination, instructing the update of examination information, inputting related information related to the examination information, or clicking on an icon indicating the imaging equipment. Therefore, the system can notify the user of the appropriate imaging equipment for the location of their rounds at any of the following times: when the user specifies an examination to be radiographed, when the user instructs the system to update the examination information, when the user enters patient information as related information, or when the user clicks an icon indicating imaging equipment. therefore,
