Description

The present invention relates to a radiation imaging apparatus, quality information acquisition method, and program.

Conventionally, when radiographers and other users make rounds of patients in the wards of medical facilities such as hospitals, mobile radiographers use flat panel detectors (FPDs) to capture radiation (X-ray) images of patients at the rounds. A radiation imaging apparatus (a rounding car) is known.

For example, by the user's operation before going to rounds, along with obtaining an imaging order from HIS (Hospital Information System: Hospital Information System) / RIS (Radiology Information System: Radiology Information System), An X-ray imaging apparatus that acquires and displays a radiographic image from a PACS (Picture Archiving and Communication System) is known (see Patent Document 1). At the time of imaging, the user checks the imaging conditions with reference to the displayed past radiation and aligns the subject.

Embodiments according to the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the present invention is not limited to the illustrated examples.

First, referring to FIGS. 1 to 3, the device configuration of this embodiment will be described. FIG. 1 is a schematic configuration diagram showing a radiation imaging system 100. As shown in FIG. FIG. 2 is a block diagram showing the configuration of the FPD1. FIG. 3 is a block diagram showing the configuration of the medical vehicle RC.

As shown in FIG. 1, a radiation imaging system 100 as a radiation imaging apparatus according to this embodiment is installed in a medical facility such as a hospital. A user U, such as a radiographer at a medical facility, moves to a hospital ward, operating room, or other destination of the patient together with the radiation imaging system 100 when making rounds of a patient to be round, and takes radiographs of the patient. Here, the rounds are performed in a hospital ward, a bed B is installed in the hospital ward, and radiography is performed in a state in which a subject S, who is a patient to be examined, is in a lying position on the bed B with his back raised. An example of doing so will be explained.

The radiation imaging system 100 includes an FPD 1 as a detection unit and a medical cart RC. The medical cart RC has a radiation generator 2 as an irradiation unit and a console 3 . The FPD 1 and the medical vehicle RC can communicate with each other, for example, via wireless communication. In addition, the rounding car RC can be connected to a communication network (LAN (Local Area Network), etc.) in the medical facility at the waiting place (storage place) before the rounds, and is it possible to connect to the communication network at the rounds destination? , the communication with the communication network shall be fragile.

Also, the medical vehicle RC can communicate with external devices such as the HIS, RIS 60, and external device 70 (FIGS. 5(a) and 5(b)) via the communication network. Also, although the communication network is assumed to be wireless, it may be wired.

The FPD 1 is a device that generates radiographic image data according to the radiation R emitted from the radiation generator 2, is configured in a panel shape, and is portable. For this reason, the FPD 1 can of course be used by being loaded on an imaging table. Alternatively, as shown in FIG. 1, the FPD 1 can be used by placing it upright between the subject S who is sitting on a bed B or a wheelchair with the back raised and the backrest. .

In addition, the radiation incident surface of the FPD 1 loaded on the imaging table (the surface facing the subject S) is parallel or orthogonal to the horizontal plane, but the imaging table is not used (bed B or wheelchair). In imaging, the plane of incidence of radiation may not always be parallel or perpendicular to the horizontal plane (tilted). Further, the FPD 1 may move along with the movement of the subject S when it is interposed between the subject S and a soft device such as the bed B.

The radiation generator 2 includes a generator body 21 , an irradiation instruction switch 22 , a tube 23 , a tube support section 24 , a collimator 25 and an FPD storage section 26 . Further, the radiation generator 2 can be moved by wheels provided on the housing of the generator main body 21 .

The irradiation instruction switch 22 outputs an operation signal to the generator body 21 when it is operated (depressed) by the user U. As shown in FIG. Although FIG. 1 illustrates a state in which the irradiation instruction switch 22 is connected to the generator main body 21 by wire, the irradiation instruction switch 22 and the generator main body 21 may be connected wirelessly.

Triggered by the operation of the irradiation instruction switch 22, the tube 23 emits radiation R (such as X-rays) at a dose corresponding to preset imaging conditions in a manner corresponding to the imaging conditions, and emits radiation from the irradiation port. Irradiate.

The tube support portion 24 is an arm that supports the tube 23 . The tube support portion 24 has a support portion 241 extending from the generator main body 21 to an upper tip, and a support portion 242 extending forward from the upper portion of the support portion 241 . A tip portion of the support portion 242 supports the tube 23 . In addition, the tube support section 24 has a joint mechanism (not shown) so that the tube 23 can be moved in the X-axis direction (front-rear direction of the radiation generator 2 (horizontal direction in FIG. 1)) and the Y-axis perpendicular to the X-axis. It is possible to move in the direction (the width direction of the radiation generator 2 (the direction orthogonal to the paper surface of FIG. 1)) and the Z-axis direction (the vertical direction (vertical direction in FIG. 1)) orthogonal to the X-axis and the Y-axis. The tube support 24 rotates the tube 23 about a rotation axis parallel to the X-axis, Y-axis, and Z-axis by a joint mechanism (not shown) to change the direction of the irradiation port of the radiation R. It is possible to change.

The collimator 25 is attached to the irradiation port of the tube 23 and constricts the radiation R so that the irradiation field of the radiation R emitted from the irradiation port has a preset rectangular shape. The collimator 25 also has a lamp button (not shown). Triggered by the operation of the lamp button by the user, visible light is emitted to the range of the irradiation field of the radiation R. As shown in FIG.

The FPD storage unit 26 stores the FPD 1 when not in use, and is provided on the side surface of the generator main body 21 . Also, the FPD storage unit 26 can store a plurality of FPDs 1 . A connector (not shown) is provided in the FPD storage unit 26, and when the FPD 1 is stored, the connector 16a (FIG. 2) of the FPD 1 may be connected.

The console 3 is composed of a PC (Personal Computer), a mobile terminal, or a dedicated device, and is mounted on the radiation generator 2 . The console 3 controls at least one of the FPD 1 and the radiation generator 2 based on an imaging order acquired from an external device (such as the RIS 60 (FIG. 5A)) or an operation performed on the operation unit 32 by the user U. Imaging conditions (tube voltage, tube current and irradiation time or current-time product (mAs value), imaging site, imaging direction, etc.) can be set in the apparatus. The imaging order is information related to radiography requested by the clinician to the user, and includes the specified date and time of radiography, subject information of the subject to be imaged (patient ID described later), imaging site (imaging site described later). ID, etc.), a purpose ID, which will be described later, and information on shooting content. Also, the console 3 can acquire radiation image data generated by the FPD 1, store it in itself, or transmit it to another external device (such as PACS).

Radiography (sitting-position radiography) using the radiography system 100 (carrying car RC) configured as described above is performed as follows. First, the user U places the radiation imaging system 100 near the subject S (on the side of the bed B). Then, the user U makes the subject S assume a sitting posture. The user U appropriately adjusts the angle of the backrest of the bed B when the subject S sits on an angle-adjustable device (such as a bed B that can be partially erected). Then, the approximate position and orientation of the tube 23 are adjusted so that the irradiation port of the tube 23 faces the body part of the subject S to be imaged. Then, the FPD 1 is taken out from the FPD storage section 26, and the FPD 1 is arranged between the back of the subject S and the backrest section. Then, the direction of the tube 23 and the irradiation field are finely adjusted so that the irradiation axis of the radiation R is orthogonal to the radiation incident surface of the FPD 1 . Then, radiography is performed (radiation R is applied to the imaging region of the subject S, and radiographic image data of a still image or dynamic image of the region to be diagnosed is generated on the FPD 1).

The generator body 21 and the console 3 are integrated (may be housed in one housing), but they may be separate. Moreover, the radiation generator 2 may be movable by means other than wheels. For example, the radiation generator 2 may be light enough to be carried by a person or mounted on a commercially available trolley, or may have a smooth bottom surface that slides on the floor surface. good. In the radiation imaging system 100, one of the FPD 1 and the radiation generator 2 may be installed in a room of a medical facility (the other is freely movable).

Next, the internal configuration of the FPD 1 will be described with reference to FIG. As shown in FIG. 2 , the FPD 1 includes a radiation detection section 11 , a scan drive section 12 , a readout section 13 , a control section 14 , a storage section 15 , a communication section 16 and a sensor section 17 . Each part of FPD1 is connected for communication.

The radiation detection unit 11 includes a scintillator (not shown) and a photoelectric conversion panel 111 . The scintillator is made of, for example, CsI columnar crystals and formed in a flat plate shape. Upon receiving radiation, the scintillator emits an electromagnetic wave (for example, visible light) having a longer wavelength than the radiation at an intensity corresponding to the dose (mAs) of the received radiation. Also, the scintillator is arranged so as to extend parallel to the radiation incident surface of the housing of the radiation detection unit 11 .

The photoelectric conversion panel 111 is arranged so as to extend parallel to the scintillator on the side opposite to the surface of the scintillator facing the radiation incident surface. The photoelectric conversion panel 111 has a substrate 111a and a plurality of charge storage units 111b. The plurality of charge storage units 111b are arranged two-dimensionally (for example, in a matrix) on the surface of the substrate facing the scintillator, corresponding to each pixel of the radiographic image. Each charge storage unit 111b includes a semiconductor element that generates an amount of charge corresponding to the intensity of the electromagnetic wave generated by the scintillator, and a switch element that is provided between each semiconductor element and the wiring connected to the readout unit 13. , respectively. A bias voltage is applied to each semiconductor element from a power supply circuit (not shown). Each charge storage unit stores and discharges a charge to be read out as a signal value according to the received radiation by switching the switching element between the ON state and the OFF state.

The scan drive unit 12 applies an ON voltage or an OFF voltage to each scanning line 111c of the radiation detection unit 11, thereby switching each switch element to an ON state or an OFF state.

The readout unit 13 reads out the amount of charge that has flowed from the charge accumulation unit 111b through each signal line 111d of the radiation detection unit 11 as a signal value. Note that the reading unit 13 may perform binning when reading the signal value.

The control unit 14 has a CPU (Central Processing Unit) and a RAM (Random Access Memory) (not shown). The CPU reads various processing programs stored in the storage unit 15, expands them in the RAM, and executes various processes in cooperation with the expanded processing programs, thereby comprehensively controlling the operation of each unit of the FPD 1. do. Further, the control unit 14 generates radiation image data based on the plurality of signal values read by the reading unit 13 .

The storage unit 15 is configured by a semiconductor memory, a HDD (Hard Disk Drive), or the like, and stores various programs executed by the control unit 14, parameters necessary for executing the programs, and various data of files. Note that the storage unit 15 may be capable of storing image data of radiation images.

The communication unit 16 is composed of a communication module for wireless communication and the like. The communication unit 16 transmits/receives various signals and various data to/from an external device such as a medical vehicle RC connected by wireless communication.

The sensor unit 17 is a detection unit for information necessary to calculate the opposing angle between the FPD 1 and the tube 23 . The sensor unit 17 is a triaxial acceleration sensor. The 3-axis acceleration sensor detects acceleration acting in 3-axis (x-axis, y-axis, and z-axis) directions, and outputs acceleration information of the detected acceleration in the 3-axis directions to the control unit 14 . Only gravitational acceleration acts on the stationary three-axis acceleration sensor. Therefore, the three-axis acceleration sensor detects three-axis direction components of gravitational acceleration in a stationary state.

Note that the sensor unit 17 may be a 6-axis sensor or a 9-axis sensor. The 6-axis sensor is obtained by adding a function of detecting angular velocities (gyro) on each of the 3 axes to the 3-axis acceleration sensor. The 9-axis sensor is obtained by adding the function of detecting the azimuths of the 3 axes (north, south, east, and west) to the 6-axis sensor.

For example, when a predetermined condition is established, the control unit 14 causes the sensor unit 17 to repeatedly detect acceleration information of gravitational acceleration in three axial directions. The predetermined conditions include, for example, that the power of the detector 1 is turned on, that a predetermined control signal is received from another device (such as the medical vehicle RC), and that a predetermined operation is performed on the operation unit (not shown) of the FPD 1. including what has been done. The control unit 14 transmits the detected acceleration information of the gravitational acceleration to the medical vehicle RC via the communication unit 16 every time the sensor unit 17 detects the acceleration information of the gravitational acceleration.

As an operation of the control unit 14, for example, the control unit 14 causes the scan driving unit 12 to perform charge accumulation/discharge in the radiation detection unit 11 in synchronization with the timing at which the radiation R is emitted from the radiation generation device 2. Execute control. Further, the control unit 14 executes control to cause the readout unit 13 to read out signal values based on the charges emitted by the radiation detection unit 11 . Based on the signal values read by the reading unit 13, the control unit 14 also generates radiographic image data of a still image or a dynamic image according to the dose distribution of the irradiated radiation R. FIG. When generating radiographic image data of a still image, the control unit 14 generates radiographic image data only once per depression of the irradiation instruction switch 22 . Further, when generating radiographic image data of a dynamic image, the control unit 14 generates radiographic image data of frames constituting the dynamic image a plurality of times (for example, one 15 times per second). In addition, the control unit 14 transmits the generated radiographic image data to an external device (such as a mobile medical vehicle RC) via the communication unit 16 .

The FPD 1 is not limited to an indirect conversion type that converts radiation into an electric signal via a scintillator as described above, and a direct conversion type that directly converts radiation into an electric signal by a semiconductor element. good.

Next, referring to FIG. 3, the internal configuration of the radiation generator 2 and the console 3 of the medical cart RC will be described. As shown in FIG. 3, the radiation generator 2 includes a generator main body 21, an irradiation instruction switch 22, a tube 23, a tube support 24, a collimator 25, an FPD storage section 26, a sensor section 27, and a sub display.

The sensor section 27 is provided on the tube 23 and is a three-axis acceleration sensor similar to the sensor section 17 . Note that the sensor unit 27 may be a 6-axis sensor or a 9-axis sensor. Further, the sensor that constitutes the sensor section 27 may be of a different type from the sensor that constitutes the sensor section 17 . The control unit 211 receives the acceleration information of the gravitational acceleration in the three axial directions received from the stationary FPD 1 via the communication unit 214, and the acceleration information of the gravitational acceleration in the three axial directions detected by the sensor unit 27 in the stationary tube 23. , the opposing angle between (the radiation incident surface of) the FPD 1 and (the surface perpendicular to the radiation irradiation direction) of the tube 23 is calculated.

The sub-display unit 28 is configured by a display unit such as an LCD (Liquid Crystal Display) or an EL (Electro-Luminescence) display, and is provided near the tube 23, for example. The sub-display unit 28 displays display information such as various images according to display information input from the control unit 211 . It is assumed that the sub-display unit 28 and the optical imaging unit 2A are provided in the housing of the collimator 25. FIG. The sub-display unit 28 and the optical imaging unit 2A may be provided in the housing of the tube 23 or may be provided in the tube support unit 24 . Further, the display contents of the sub-display section 28 are separated from the display contents of the main display section 31 .

Distance measurement unit 29 is a measurement unit that measures SID (Source Image Distance), and outputs the measured SID to control unit 211 . SID is the distance between the focal point F of the radiation R and the imaging surface of the FPD 1 (the surface on which the charge storage unit 111b in the radiation detection unit 11 is provided). Note that the distance measurement unit 29 may be configured to measure SSD (Source Skin Distance). SSD is the distance between the focus F of the radiation R and the body surface of the subject S, and is approximately equal to the difference between the SID and the body thickness of the subject S. A distance measuring unit 29 is provided in the collimator 25 .

The distance measuring unit 29 includes, for example, light emitting means for emitting laser light, detection means for detecting reflected laser light, and light emitting means based on the time from when the laser light is emitted to when the reflected laser light is detected. and an optical image of the FPD 1 generated by the optical imaging unit 2A for optically imaging the FPD 1 in the irradiation direction of the radiation, and the optical image of the FPD 1 It may be composed of calculation means for calculating the SID based on the size information, or may be a combination thereof. In addition, since the laser light is reflected on the body surface of the subject S, the distance measured by the distance measuring unit 29 using the laser light is often SSD. In this case, the SID is obtained by adding the body thickness of the subject S to the measured SSD. The body thickness may be a predetermined reference value, a numerical value input by the user U, or automatically calculated from the subject S information.

The control unit 211 controls three-axis acceleration information of the FPD 1 from the sensor unit 17 (inclination information (orientation) of the radiation incident surface of the FPD 1 with respect to the horizontal plane calculated from the information) and three-axis acceleration information of the tube 23 from the sensor unit 27. Alignment including (inclination information (orientation) of the plane perpendicular to the radiation irradiation direction of the tube 23 (collimator 25) with respect to the horizontal plane calculated from) and the distance between the FPD 1 and the tube 23 by the distance measurement unit 29 Calculate information. The tilt information of the FPD 1 may be represented by a difference value from the tilt information of the tube 23 (collimator 25). The user can grasp the arrangement of the FPD 1 and the tube 23 (collimator 25) in the radiography from the alignment information of the past radiography, and adjust the arrangement of the FPD 1 and the tube 23 (collimator 25). The alignment information may be a single alignment of only the tilt information of the tube 23 .

The optical imaging unit 2A has an optical system such as a lens, and an imaging device such as a CCD (Charge Coupled Device) or a CMOS (Complementary Metal Oxide Semiconductor). Under the control of the control unit 211, the optical imaging unit 2A optically images the subject S as a subject with visible light, generates optical image data, and outputs the optical image data to the control unit 211 and the like. The optical imaging unit 2A optically images the subject S to generate optical image data of a still image or a dynamic image (live image, etc.).

The control unit 211 is composed of a CPU, a RAM, and the like. Then, the CPU reads various programs stored in the storage unit 212, develops them in the RAM, executes various processes in cooperation with the developed programs, and controls each unit of the radiation generator 2 and the console 3. do.

The storage unit 212 is composed of a non-volatile memory, HDD, or the like, and stores various types of data such as various programs executed by the control unit 211 and parameters and files necessary for executing the programs. In particular, the storage unit 212 stores a first quality information acquisition program for executing a first quality information acquisition process, which will be described later, a navigation program for executing a navigation process, which will be described later, and a judgment support process, which will be described later. It is assumed that a judgment support program for execution and a photographing purpose table 400, which will be described later, are stored.

The generator 213 applies a voltage corresponding to preset imaging conditions to the tube 23 and energizes the tube 23 with a current corresponding to the imaging conditions when the imaging instruction signal is received from the control unit 211 . .

The audio output unit 33 is composed of an amplifier, a speaker, etc., and outputs audio according to audio information input from the control unit 211 . For example, the voice output unit 33 outputs the synthesized voice of the message as imaging support information, which is information for assisting the user U in radiography. The imaging support information is information based on quality information, and is information for supporting (assisting) radiation imaging of a subject to be imaged and improving the image quality of radiation image data. The quality information is information for evaluating the image quality of radiation image data according to the purpose of radiography.

Next, referring to FIG. 4, information to be stored in the medical vehicle RC will be described. FIG. 4 is a diagram showing the structure of the imaging purpose table 400. As shown in FIG.

It is assumed that the imaging purpose table 400 is stored in the storage unit 212 of the medical vehicle RC. The imaging purpose table 400 is a table that defines quality information of image quality according to the imaging purpose acquired by the mobile car RC in radiation imaging during medical rounds. The purpose of imaging is the type of examination for the purpose of using the radiographic image data of the subject taken during rounds, and includes “follow-up,” “initial examination,” “identification of disease,” and “confirmation of the position of an intubated object such as a tube.” ”, ”Confirmation of the situation of patients transported by ambulance”, etc. In addition, the purpose of imaging may differ depending on the clinical department and the type of disease. In the case of ward rounds, when the wards are divided by clinical departments, it is possible to narrow down the imaging purpose to some extent by specifying the wards instead of the clinical departments.

Image quality refers to the quality that the visibility of lesions and medical instruments such as catheters in radiographic image data is necessary and sufficient for the purpose of examination and diagnosis by clinicians, and/or radiographic image data (dynamic It is a quality that satisfies the requirements for executing image analysis processing using images (including images). The requirements are, for example, signal value, graininess, contrast, positioning of the analysis target part, presence or absence of streaks and artifacts. For example, in the case of radiographic image data of dynamic images, whether or not a certain number of frames that meet the requirements for image quality are secured, and whether or not the minimum required imaging time (frames) for image analysis is secured. , whether patient motion (such as breathing) continues or stops for a period of time, whether there are gaps, whether the frame rate is adequate, and so on. The blank area refers to a portion (a portion consisting only of air) in which there is no subject (imaged part of the subject) in the radiographic image data. Since there are no obstacles in the unobstructed part, there is a large dose of radiation, so if you compare the pixel values together with the object range, the correct values such as average and maximum will not be obtained. Calculations are performed by excluding unobtrusive parts and artifacts. Even for the same imaging site (imaging order), the observation site and radiographic image data comparison target (same patient's previous radiographic image data, other patient's radiographic image data, etc.) differ depending on the imaging purpose. There are also different criteria for judging image quality. The quality information is not information for setting imaging conditions as in Patent Document 1, but information for evaluating the image quality of captured radiographic image data.

As shown in FIG. 4, the shooting purpose table 400 has items (columns) of a purpose ID 401 and quality information 402 . The purpose ID 401 is identification information of the imaging purpose of radiation imaging. The quality information 402 is the content of the quality information acquired by the medical vehicle RC from the external device (RIS 60 (FIG. 5A)) corresponding to the imaging purpose (and imaging site) of the purpose ID 401 . In the illustration of quality information 402 in FIG. 4, a "patient" is a subject. The “imaging site” is the site of the subject to be imaged, for example, chest recumbent position AP (radiation irradiated from the front (Anterior) (ventral side) to the posterior (dorsal side)) shooting). “Alignment adjustment history” is history information of adjustment of alignment information of the tube 23 and the FPD 1 . “EI (Exposure Index)” is an index indicating the incident dose to the FPD 1 . The "S value" is the sensitivity corresponding to the radiation dose during radiography.

In the imaging purpose table 400, for example, the purpose ID 401 is assumed to be "0001" when the imaging region is chest recumbent AP and the imaging purpose is "follow-up observation". It is also assumed that the purpose ID 401 is "0002" when the imaging region is the chest recumbent AP and the imaging purpose is "initial medical examination". The purpose ID 401 (quality information) is associated with at least one of an imaging site (imaging site ID), a subject (patient ID), a user (user ID of a radiographer), and a clinician (clinician ID). It may be assumed that As an example in FIG. 4, the quality information 402 corresponding to the purpose ID 401 has a plurality of items. However, an ID may be assigned to one piece of quality information, and the IDs may be grouped under the purpose ID. Also, the unit and setting range (or threshold value) of each item may be defined in a form relative to the quality information 402 . For example, for "past" data, there is a setting such that inspections up to several generations ago are targeted.

Here, Table I below shows an example of the imaging purpose, quality information, and determination support information in this embodiment. Judgment support information is information based on quality information, and is used by the user to judge whether or not the captured radiographic image data satisfies a predetermined image quality (whether or not re-imaging is required). This is support (auxiliary) information for improving the image quality of radiographic image data.

The image data (, image) in Table I is radiation image data (, radiation image), but may include optical image data (, optical image).

Next, the operation of the radiation imaging system 100 will be described with reference to FIGS. 5(a) to 8. FIG. FIG. 5(a) is a block diagram showing the flow of data in the medical cart RC before radiography. FIG. 5(b) is a block diagram showing the flow of data in the medical cart RC after radiography. FIG. 6 is a flowchart showing the first quality information acquisition process. FIG. 7 is a flowchart showing navigation processing. FIG. 8 is a flow chart showing the judgment support process.

As shown in FIG. 5(a), the terminal device 50, the RIS 60, the external device 70, and the medical care vehicle RC at the standby place are installed in advance in the medical facility as relay devices (access points connected to the communication network). , other mobiles, consoles, etc.). The terminal device 50 is a terminal device such as a PC used by a clinician. The RIS 60 is a RIS (radiology information system) server, and may be a HIS (hospital information system) server. The external device 70 is a server that manages quality information and stores the quality information. The external device 70 may overlap with the RIS 60 and HIS.

When radiography is to be performed on a subject at the rounds, the terminal device 50 receives the imaging date and time of the radiation imaging from the clinician, the designation information of at least one subject (patient) to be imaged, the imaging site, the imaging The RIS 60 issues an imaging order including an imaging date and time, a patient ID corresponding to patient designation information, an imaging region ID corresponding to an imaging region, and a purpose ID corresponding to the imaging purpose. Send to The photographing order issued by the terminal device 50 is an order for one photographing unit, and since photographing conditions and the like are targets, the photographing order is a photographing unit (image unit). The RIS 60 receives a radiographing order from the terminal device 50, stores it in its own storage unit, issues a radiographing order (RIS order) based on the received radiographing order, and transmits the radiographing order to the medical car RC. An imaging order (RIS order) issued by the RIS 60 is an order for one radiographic examination unit, and is generally an examination order. An inspection order is an order for one inspection unit, and includes a plurality of imaging orders (issued by the terminal device 50).

A user such as a radiographer goes to a waiting place where the FPD 1 and the medical car RC are located. Triggered by the start of reception of an imaging order from the RIS 60 via the communication unit 214, the control unit 211 sets the first quality stored in the storage unit 212 in the medical care car RC (console 3), for example. A first quality information acquisition process is executed according to the information acquisition program.

As shown in FIG. 6, first, the control unit 211 completes reception of the imaging order from the RIS 60 and obtains it via the communication unit 214 (step S11). Then, the control unit 211 refers to the imaging purpose table 400 stored in the storage unit 212, and determines the quality information to be acquired from the quality information 402 corresponding to the purpose ID 401 of the imaging order acquired in step S11 ( step S12).

Then, the control unit 211 transmits a request for the quality information determined in step S12 including the patient ID, purpose ID, and imaging site ID of the imaging order to the external device 70 via the communication unit 214, and transmits the quality information. It is received and acquired from the external device 70 (step S13). In response to step S13, the external device 70 receives the request for quality information from the medical vehicle RC, and stores the quality information corresponding to the patient ID, purpose ID, and imaging site ID in the request for quality information in its own storage unit. , and transmits it to the rounding car RC.

Then, the control unit 211 stores the quality information acquired in step S13 in the storage unit 212 in association with the imaging order (step S14), and ends the first quality information acquisition process.

In addition, if the communication environment is such that the communication network can be used in the route between the rounding destination and the waiting room and the rounding destination, The control unit 211 of the medical vehicle RC may be configured to execute the first quality information acquisition process.

After execution of the first quality information acquisition process, the user goes from the waiting room to the rounds destination of the subject to be imaged together with the vehicle RC in which the FPD 1 is stored, and starts radiation imaging of the subject. At this time, the control unit 211 stores in the storage unit 212, triggered by, for example, the user inputting an instruction to execute navigation processing via the operation unit 32 in the rounding vehicle RC (console 3) to which the rounds are made. Navigation processing is executed according to the navigation program.

As shown in FIG. 7, first, the control unit 211 reads out all the shooting orders from the storage unit 212 and displays them on the main display unit 31, and through the operation unit 32, the shooting order among the displayed shooting orders from the user. A selection input of an imaging order of a subject (patient) to be examined is accepted (step S21).

Then, the control unit 211 reads and acquires the quality information for supporting the radiography from the storage unit 212 corresponding to the radiography order selected and input in step S21, and combines the acquired quality information with the quality information for the current radiography. Various types of information are acquired (step S22). The quality information in step S22 is, for example, optical image data at the time of past radiography. The various information of the current radiography in step S22 is information related to the current radiography, such as alignment (panel alignment) information between the FPD 1 and the tube 23, dose of the tube 23, and the like. Then, the control unit 211 generates imaging support information for supporting radiation imaging of the subject to be imaged from the round imaging information acquired in step S22 (step S23). Then, the control unit 211 displays the imaging support information generated in step S24 on the main display unit 31 to navigate radiography (step S24).

Then, the control unit 211 performs radiation imaging of the subject using the FPD 1 and the radiation generator 2 in accordance with an operation input regarding radiation imaging from the user via the operation unit 32 and the irradiation instruction switch 22, and performs radiation imaging of the subject. Radiographic image data of the examiner is obtained from the FPD 1 (step S25). Then, the control unit 211 controls various information (radiation image data, imaging order, alignment information based on alignment measurement of the tube 23 and the FPD 1 by optical imaging by the optical imaging unit 2A, alignment information of the tube 23, and dose, optical image data, EI, S value, etc.) are associated with each other and stored in the storage unit 212 (step S26), and the navigation processing ends.

When evaluating the image quality of radiographic image data based on the quality information, the control unit 211 performs image processing on the radiographic image data after radiographic imaging in step S25 of the navigation processing, and the past radiographic image data of the quality information is evaluated. can be converted into radiographic image data that can be easily compared with radiographic image data to support the evaluation of captured radiographic image data (determination of imaging failure of radiographic image data, which will be described later). Image processing includes, for example, region extraction, contour extraction, temporal difference, bone removal, shift amount calculation, and left/right determination. Alternatively, the control unit 221 may automatically perform the imaging failure determination without moving to the next step of the imaging failure determination by the user based on the evaluation of the radiographic image data, and shift to the step of re-imaging.

After the navigation processing is executed, the user starts to judge whether or not the radiographic image data captured in the navigation processing is defective. At this time, the control unit 211 causes the storage unit 212 to store a Navigation processing is executed according to the stored decision support program.

As shown in FIG. 8, first, the control unit 211 reads and acquires the quality information for assisting the determination of the shooting error from the storage unit 212, corresponding to the shooting order selected and input in step S21 of the navigation processing. , the acquired quality information and various information at the time of radiography in step S25, and generation of judgment support information for assisting judgment of whether or not the radiographic image data stored in step S26 was photographed (step S41). The quality information in step S41 is, for example, past radiation image data. Various information at the time of radiography in step S41 is information for supporting determination of imaging failure, and includes, for example, alignment (panel alignment) information between the FPD 1 and the tube 23, EIT (target exposure index: target dose index) and S value. In place of or in addition to the EIT and S value of various information at the time of radiography, an exposure index related to radiation image noise described in Japanese Patent Application Laid-Open No. 2020-130796 may be used.

Then, the control unit 211 displays the determination support information generated in step S41 on the main display unit 31 together with at least the radiation image data among the various information stored in step S26 of the navigation processing (step S42). Corresponding to step S43, the user refers to the displayed radiation image data and determination support information to determine whether or not the radiation image data was captured.

Then, the control unit 211 accepts an input of the radiographic image data imaging necessity judgment result from the user via the operation unit 32, and provides judgment support information in association with the radiographic image data and the radiographic imaging necessity judgment result. It saves in the storage unit 212 (step S43).

Then, the control unit 211 transmits the radiation image data associated with the patient ID, imaging site ID, and purpose ID of the imaging order to the RIS 60 via the communication unit 214 (step S44). In step S44, as shown in FIG. 5B, the RIS 60 receives the radiographic image data associated with the imaging order from the medical vehicle RC, stores it in its own storage unit, and transmits it to the terminal device 50. do. The terminal device 50 receives the radiation image data associated with the radiographing order from the RIS 60 and displays it on its own display unit. The clinician observes the radiographic image of the radiographic image data of the subject to be visited, displayed on the terminal device 50 .

Then, the control unit 211 transmits the determination support information and the imaging result information associated with the patient ID, imaging region ID, and purpose ID of the imaging order to the external device 70 via the communication unit 214 (step S45), End the decision support information. The imaging result information includes radiation image data associated with the patient ID, imaging region ID, and purpose ID of the imaging order, the determination result of whether or not imaging is necessary, and other various information (optical image data etc.), including the date and time the photo was taken. In step S45, as shown in FIG. 5B, the RIS 60 receives the determination support information and the imaging result information associated with the imaging order from the medical vehicle RC and stores them in its own storage unit. This imaging result information can also be used as quality information from the next time onwards.

Also, the quality information stored in the external device 70 to be used from the next time onwards is not limited to the imaging result information. It may be information (a memo of a failure example, points to note at the time of imaging linked to the patient ID, etc.). As for the storage operation of the memo information, it is preferable that the memo information can be stored in the storage unit 212 or the external device 70 simply by checking a check box displayed on the main display unit 31 via the operation unit 32 by the user. preferable. Further, the medical care vehicle RC may be provided with a voice input unit such as a microphone, and the memo information of the user may be input by voice through the voice input unit.

Also, in the imaging result information, radiographic image data obtained by radiographic imaging and optical image data obtained by optical imaging in the radiographic imaging are associated with each other. In addition, regarding the quality information, it may be configured such that the allowable range of the level of the quality information is expanded according to the condition of the patient.

Also, the quality information stored in the external device 70 may be calibrated by the external device 70 . For example, the user consults with a clinician based on the quality information stored in the external device 70 . The external device 70 corrects radiographic image data (optical image data) as a reference (for comparison) of stored quality information and various data in accordance with an operation input by a user or a clinician. Outliers (noise) in the quality information are filtered out. For example, radiography that had to be taken under conditions that do not satisfy quality standards due to patient conditions, operation test radiography, and the like may be excluded or corrected as outliers of quality information.

Note that the information stored in the external device 70 may also be stored in the storage unit 212 in the same manner, and may be reused in subsequent imaging. Depending on the capacity of the storage unit 212, the quality information acquired in step S13 may also be continuously held, thereby reducing the acquisition processing cost for pre-acquisition at the next examination of the same patient (examinee). Also, the external device 70 may be used as a portable storage unit for the medical vehicle RC by using an external semiconductor memory (such as an SSD (Solid State Drive)) or HDD. As a result, the transmission processing (step S45) from the medical care vehicle RC to the external device 70 is separated, and the control unit 211 of the medical care vehicle RC transmits judgment support information, imaging result information, quality information, etc. to the external semiconductor memory or HDD. , the transmission processing load on the external device 70 is reduced. Then, the control unit 211 may read the judgment support information, the photographing result information, and the like from an external semiconductor memory or HDD and output (transmit) them to the external device 70 at any opportunity.

As described above, according to the present embodiment, the radiation imaging system 100 as a radiation imaging apparatus includes the radiation generator 2 as an irradiation unit for irradiating a subject as a subject with radiation, and detecting the radiation to detect the subject. The FPD 1 as a detection unit that performs radiography to generate radiographic image data, and the quality for acquiring an imaging order related to radiography of a subject and evaluating the image quality according to the imaging purpose of radiography based on the imaging order. and a control unit 211 that acquires information from an external device and stores it in the storage unit 212 .

Therefore, based on the quality information, the user (especially, even a user who is not accustomed to round imaging) can evaluate the image quality of the radiographic image data according to the imaging purpose at the round destination. More specifically, in the imaging support processing, the quality information can be used to indirectly evaluate and improve the image quality of radiographic image data captured with the aid of radiographic imaging. In the judgment support process, the quality information can be used to support the judgment of whether or not the radiographic image data is defective, and the image quality can be evaluated.

The control unit 211 also performs desired image processing on the radiographic image data to generate radiographic image data that can be compared with past radiographic image data of quality information. For this reason, in the judgment support processing, the image-processed radiographic image data and the radiographic image data of the quality information can be compared to more appropriately judge whether or not the radiographic image data is defective. Image quality can be further improved.

In addition, the control unit 211 acquires quality information before the movement of the FPD 1 or the movement of the FPD 1 to the destination of the rounds where the examinee is present, or before radiography. Therefore, quality information can be reliably acquired before radiation imaging (navigation processing, judgment support processing).

The imaging order also includes a purpose ID that identifies the purpose of imaging. The control unit 211 acquires quality information corresponding to the purpose ID. Therefore, it is possible to easily obtain the quality information according to the shooting purpose using the purpose ID.

The storage unit that stores the quality information is not the storage unit 212, but a separate storage unit from the medical vehicle RC (a storage unit of an external device that can communicate with the medical vehicle RC at the site of the rounds, or a storage unit that is attached to the medical vehicle RC). external storage unit, etc.). According to this configuration, the capacity of the storage unit 212 can be reduced, and the configuration of the medical vehicle RC can be simplified.
