Description

[Technical Field]

[0001] The present invention relates to a radiological image Shooting System , radiological images photograph Methods and radiographic images photograph Regarding the program. [Background technology]

[0002] In order to observe the inside of a patient's (subject's) body in real time, a fluoroscopic imaging device is known that irradiates the patient with radiation, takes images, and displays a moving image of the inside of the patient's body in real time (see, for example, Patent Document 1). For example, such a fluoroscopic imaging device is often used when performing a procedure in which a catheter is inserted into the patient's body.

[0003] Fluoroscopy equipment requires a dedicated system and is installed in a dedicated imaging room, and due to the high radiation exposure, it cannot be used in situations other than the imaging room, such as in rounds or emergency situations. Therefore, for example, in cases where it is necessary to take images to confirm the internal state of the body during follow-up observation or contrast agent injection, the patient must be moved to a dedicated imaging room to perform the imaging, regardless of their physical condition or state, which places a great burden on the patient.

[0004] In contrast to such fluoroscopic imaging devices, radiographic imaging devices that are an extension of existing imaging technology using radiation, but that use pulsed radiation to take continuous images to display video of the inside of a patient's body and perform image analysis, are beginning to become popular. Such radiographic imaging devices can be mounted on medical carts and the like, and by implementing exposure control such as setting an upper limit on the amount of radiation exposure, they make it possible to capture video even at locations where fluoroscopic imaging devices cannot be used. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 2021-023748 Summary of the Invention [Problem to be solved by the invention]

[0006] Due to limitations on the amount of radiation exposure at the patient's visit site, a radiographic imaging device cannot irradiate radiation indefinitely like a fluoroscopic imaging device, and must perform imaging within a fixed period of time. On the other hand, a radiographic imaging device may perform imaging repeatedly depending on the treatment given to the patient. Therefore, a radiographic imaging device is required to perform imaging repeatedly, taking multiple types of images multiple times within a fixed period of time. Furthermore, the number of imaging operations may change flexibly depending on, for example, the imaging conditions, the treatment conditions, etc.

[0007] However, the above-mentioned radiographic imaging device performs one imaging session for one imaging order that instructs imaging, and is not able to handle the case where imaging is performed in separate sessions (multiple imaging sessions). Therefore, when performing multiple imaging sessions, a new imaging order is required each time, and one imaging session is performed for each of the multiple imaging orders. As such, when performing multiple imaging sessions with the above-mentioned radiographic imaging device, the operation is cumbersome, and the operability for multiple images resulting from multiple imaging sessions is not good. Note that with the above-mentioned fluoroscopic imaging device, in order to record images obtained by imaging in response to an imaging order, a recording operation must be performed separately from the exposure operation, and the operability is not good when multiple recording operations are performed.

[0008] The object of the present invention is to provide a radiographic imaging system that can improve the operability of the multiple images taken even when multiple images are taken during an operation based on a single imaging instruction.

[0014] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0015] [Radiation imaging device] FIG. 1 is a diagram showing an example of the overall configuration of a radiographic image capturing system including a radiographic image capturing apparatus 10 according to the present embodiment.

[0016] The radiographic imaging device 10 is, for example, a device for performing dynamic imaging of patients who have difficulty moving around during rounds. The radiographic imaging device 10 includes a device main body 1, a radiation source 2, and an FPD (Flat Panel Detector) 3. The device main body 1 has wheels and is configured as a mobile medical cart. However, the radiographic imaging device 10 may also be a portable device without wheels.

[0017] The device main body 1 is connected to a communication network N such as an in-hospital LAN (Local Area Network) via, for example, wireless communication, an AP (Access Point) 20 installed in the hospital. The device main body 1 can transmit and receive data to and from an external device via the communication network N. In this example, the external device is, for example, a RIS (Radiology Information Systems) 30, a PACS (Picture Archiving and Communication System) 40, an analysis device 50, etc.

[0018] The radiation image capturing device 10 captures radiation images (still images, dynamic images) of the subject H (patient) by irradiating radiation from the radiation source 2 with the FPD 3 positioned opposite the radiation source 2 across the subject H (patient).

[0019] In this embodiment, dynamic imaging refers to obtaining multiple images of the subject H by repeatedly irradiating the subject H with pulsed radiation such as X-rays at predetermined time intervals (pulse irradiation). A series of images obtained by dynamic imaging is called a dynamic image. A dynamic image is made up of multiple frame images. In contrast, a still image is made up of one frame image. Hereinafter, still images and dynamic images may be collectively referred to as radiation images or images.

[0020] FIG. 2 is a block diagram showing the functional configuration of the device main body 1. As shown in FIG.

[0021] The device main body 1 functions as a console (imaging control device) and also functions as a computer. As shown in Fig. 2, the device main body 1 is configured to include a control unit 101, an operation unit 102, a display unit 103, a storage unit 104, a communication unit 105, a drive unit 106, a battery 107, a connector 108, a charging unit 109, etc. The various units of the device main body 1 are connected via a bus 110.

[0022] In the radiographic imaging device 10, the radiation source 2, FPD 3, control unit 101, communication unit 105, drive unit 106, etc. correspond to the imaging unit of the present invention, which irradiates radiation and captures still images and dynamic images.

[0023] The control unit 101 is composed of a CPU (Central Processing Unit), RAM (Random Access Memory), etc. In response to input from the operation unit 102, the CPU reads out a system program and various processing programs stored in the storage unit 104, expands them in the RAM, and executes various processes according to the expanded programs.

[0024] As will be described later, the control unit 101 controls the imaging unit of the radiographic imaging device 10 to operate in an intermittent imaging mode (first imaging mode in the present invention) in which radiation images are captured multiple times between the start and end of an operation according to one imaging order. In this embodiment, an imaging order is called a main imaging order. The main imaging order corresponds to an imaging instruction in the present invention. A main imaging order ID, which will be described later and corresponds to the main imaging order, is an example of information related to imaging instructions in the present invention.

[0025] Furthermore, the control unit 101 changes (increases or decreases) the number of times of shooting in the intermittent shooting mode based on the main shooting order that instructs the intermittent shooting mode, as will be described later. Furthermore, the control unit 101 determines whether or not the number of times of shooting in the intermittent shooting mode can be increased, and increases the number of times of shooting if an increase is possible, as will be described later.

[0026] Furthermore, as will be described later, the control unit 101 associates secondary imaging orders with the primary imaging orders and sets secondary imaging orders corresponding to the number of imaging times in the intermittent imaging mode. Furthermore, when a primary imaging order is deleted, the control unit 101 also deletes the secondary imaging orders associated with the primary imaging order. A secondary imaging order corresponds to a secondary imaging instruction in the present invention. Furthermore, a secondary imaging order ID, which will be described later and corresponds to a secondary imaging order, is an example of information related to a secondary imaging instruction in the present invention.

[0027] The operation unit 102 has a touch panel or the like in which transparent electrodes are arranged in a grid pattern so as to cover the surface of the display unit 103. The touch panel detects a position pressed by a finger, a touch pen, or the like, and inputs the position information to the control unit 101 as operation information. The operation unit 102 also has an exposure switch 102a. The exposure switch 102a is a switch used by the user to instruct radiation irradiation and imaging by the radiation source 2.

[0028] The display unit 103 is configured by a monitor such as an LCD (Liquid Crystal Display) or a CRT (Cathode Ray Tube), etc. The display unit 103 performs display in accordance with an instruction of a display signal input from the control unit 101.

[0029] The storage unit 104 is configured by a non-volatile semiconductor memory, a hard disk, etc. The storage unit 104 stores various programs executed by the control unit 101, parameters required for executing processes by the programs, data of the processing results, etc.

[0030] In this embodiment, the storage unit 104 includes an examination order information storage unit 104a, an image storage unit 104b, and the like.

[0031] The examination order information storage unit 104a stores information on examination orders acquired from the RIS 30. The examination order includes, for example, patient information and examination information. The patient information includes, for example, the patient ID, name, sex, age, and hospital room (ward) of the patient to be examined. The examination information includes the examination ID, examination date, and one or more main imaging orders to be performed in the examination. The main imaging order includes the imaging region, imaging direction, imaging type (still image imaging, moving object imaging, intermittent imaging), and the like, and is represented by a RIS code.

[0032] The RIS code is a code (string of integers) for linking the radiographic imaging device 10, RIS 30, PACS 40, analysis device 50, etc. in the radiology department. The RIS code generally consists of a procedure code portion (modality, major classification, minor classification, procedure extension, etc.), a site code portion (minor site, left / right, etc.), and an imaging code portion (posture, position, imaging direction, etc.). In this embodiment, the RIS code may include a code corresponding to a preset of a secondary imaging order, which will be described later.

[0033] In this embodiment, as will be described later with reference to FIG. 6, the radiographic imaging apparatus 10 sets a main imaging order based on the RIS code of the examination order. Although multiple main imaging orders may be set based on the RIS code, in this embodiment, for simplicity of explanation, it is assumed that one main imaging order is set based on the RIS code. In this embodiment, the radiographic imaging apparatus 10 has an intermittent imaging mode as an imaging mode, and therefore multiple secondary imaging orders are set along with the main imaging order based on the RIS code corresponding to the intermittent imaging mode. The main imaging order and secondary imaging orders will be described later with reference to FIG. 5.

[0034] The main imaging order and the sub imaging order do not necessarily have to be set based on the RIS code, but may be set by the user directly inputting them from the operation unit 102 or the like.

[0035] The image storage unit 104b (storage unit in the present invention) stores radiation images transferred from the FPD 3 in association with accompanying information. The accompanying information is, for example, patient information. In this embodiment, the accompanying information also includes information about the primary imaging order (primary imaging order ID) and information about the secondary imaging order associated (linked) with the primary imaging order (secondary imaging order ID). In other words, the image storage unit 104b stores radiation images captured at the corresponding number of imaging times in association with each of multiple secondary imaging orders (secondary imaging order IDs). As a result, the image storage unit 104b stores the primary imaging order (primary imaging order ID) in association with multiple radiation images captured with the secondary imaging orders linked to the primary imaging order. With this association, the multiple radiation images captured in accordance with the secondary imaging orders are processed (managed, displayed, analyzed, etc.) in association with the primary imaging order (primary imaging order ID).

[0036] The communication unit 105 includes a first communication unit 105a and a second communication unit 105b. The first communication unit 105a transmits and receives data via wired or wireless communication with the FPD 3. The second communication unit 105b transmits and receives data with external devices such as the RIS 30 and PACS 40 connected to the communication network N via the AP 20.

[0037] The second communication unit 105b functions as an output unit that outputs data to an external device. In this case, for example, as will be described later with reference to Figs. 10 and 11, radiation images obtained by multiple imaging operations associated with a main imaging order (main imaging order ID) are output for each main imaging order (main imaging order ID) or each secondary imaging order (secondary imaging order ID).

[0038] The driving unit 106 is a circuit that drives the tube of the radiation source 2. The driving unit 106 and the radiation source 2 are connected via a cable.

[0039] The battery 107 supplies power to each part of the apparatus main body 1 and the radiation source 2. The battery 107 can be charged externally via an AC cable 111.

[0040] The connector 108 is provided inside the housing portion 120 and electrically connects to the FPD 3 housed in the housing portion 120 .

[0041] The charging unit 109 charges the FPD 3 connected via the connector 108 with power supplied from the battery 107 under the control of the control unit 101 .

[0042] The radiation source 2 is driven by the driving unit 106 to irradiate radiation (X-rays) onto the subject H. In the case of dynamic imaging, the radiation source 2 irradiates the subject H with, for example, pulsed radiation repeatedly at predetermined time intervals.

[0043] The FPD 3 is a portable radiation detector that supports still image capture and dynamic image capture, and various known FPDs can be used. The radiation irradiation from the radiation source 2 and the radiation capture by the FPD 3 are configured to be synchronized in timing by known synchronization control, for example, by time correction using time-synchronized communication.

[0044] The FPD 3 includes, for example, radiation detection elements arranged two-dimensionally on a glass substrate. The radiation detection elements are composed of semiconductor image sensors such as photodiodes. The radiation detection elements detect radiation that has been irradiated from the radiation source 2 and transmitted through at least the subject H according to its intensity, and convert the detected radiation into an electrical signal and store it. A switching unit such as a TFT (Thin Film Transistor) is connected to each radiation detection element, and the switching unit controls the storage and readout of the electrical signal to obtain image data.

[0045] The RIS 30 issues and stores an examination order. The RIS 30 also transmits the issued examination order to the device main body 1 of the radiation image capturing device 10 via the communication network N.

[0046] The PACS 40 stores and manages medical images (radiation images, etc.) generated by modalities such as the radiation image capturing apparatus 10 in association with supplementary information (patient information, examination information, etc.) of the medical images.

[0047] The analysis device 50 analyzes medical images generated by a modality such as the radiographic imaging device 10, and outputs the analysis results.

[0048] [Radiographic imaging device operation] Next, a description will be given of the imaging operation of the radiographic imaging device 10 according to the present embodiment. The radiographic imaging device 10 has, as its imaging operation, still image imaging for capturing still images and dynamic imaging.

[0049] In conventional dynamic radiography, pulsed radiation from the radiation source 2 is continuously applied from the start to the end of a single session to obtain a dynamic image consisting of a series of multiple frame images. However, from the perspective of risk management, when radiography is performed outside of an imaging room, the cumulative radiation dose that can be applied from the start to the end of a single session is limited, and long-term pulsed radiation cannot be performed. Therefore, for example, when using dynamic radiography to check the status of a catheter insertion procedure or the internal condition immediately after the administration of a contrast agent, long-term radiography is not possible, and images may not be obtained at the required timing.

[0050] Therefore, the radiographic imaging device 10 of this embodiment has a normal mode and an intermittent imaging mode as dynamic imaging operation modes. Fig. 3 is a diagram schematically showing pulse irradiation in the normal mode. Fig. 4 is a diagram schematically showing pulse irradiation in the intermittent imaging mode.

[0051] The normal mode (an example of the second imaging mode in the present invention) is a mode in which dynamic imaging is performed in the same manner as in the past. As shown in FIG. 3, the normal mode is a mode in which pulse irradiation from the radiation source 2 is performed continuously from the start to the end of one imaging session. In this way, the normal mode is a mode in which dynamic image imaging is performed once. In the normal mode, one dynamic image composed of a series of multiple frame images is obtained. Note that the still image imaging (an example of the second imaging mode in the present invention) is a mode in which still image imaging is performed once. In still image imaging, one still image composed of one number of frame images is obtained.

[0052] As shown in FIG. 4, the intermittent imaging mode is a mode in which there are imaging periods and imaging suspension periods between the start and end of one operation, and dynamic imaging, in which pulse irradiation from the radiation source 2 is continuously performed intermittently multiple times. In the intermittent imaging mode, dynamic images consisting of a series of multiple frame images are obtained multiple times. The intermittent imaging mode is not limited to dynamic imaging, and may also include still image imaging. In the intermittent imaging mode, each of multiple imaging sessions (multiple imaging sessions including one or both of still image imaging and dynamic imaging) is referred to as intermittent imaging. In this embodiment, the start of an operation in the intermittent imaging mode is referred to as the start of the operation, the end of the operation in the intermittent imaging mode is referred to as the end of the operation, and the period from the start of the operation to the end of the operation is referred to as the operating period. The start of one intermittent imaging session is referred to as the start of the intermittent imaging session, and its end is referred to as the end of the intermittent imaging session.

[0053] In this embodiment, the radiographic imaging device 10 sets a main imaging order and a secondary imaging order based on the examination order (RIS code) transmitted from the RIS 30. Fig. 5 is a diagram for explaining the main imaging order and the secondary imaging order.

[0054] As described above, the examination order includes a RIS code. For the sake of explanation, the RIS codes corresponding to still image capture, dynamic image capture, and intermittent image capture are assumed to be A, B, and C, respectively. The radiographic imaging device 10 sets a main imaging order ID based on the RIS code of the examination order transmitted from the RIS 30. Here, the main imaging order IDs corresponding to the RIS codes A, B, and C are assumed to be a, b, and c, respectively.

[0055] As shown in FIG. 5, the main imaging order ID corresponding to RIS code A is a. The imaging corresponding to main imaging order ID: a is still image imaging. Therefore, the main imaging order with main imaging order ID: a does not have a secondary imaging order, and the specified maximum number of images for the main imaging order is 1. Therefore, the radiographic imaging device 10 sets the main imaging order ID: a based on the RIS code transmitted from the RIS 30. Then, the radiographic imaging device 10 performs still image imaging to capture one still image in accordance with the main imaging order with main imaging order ID: a, and stores the captured one still image (one still image) in association with the main imaging order ID: a.

[0056] As shown in FIG. 5, the main imaging order ID corresponding to RIS code B is b. The imaging corresponding to main imaging order ID: b is dynamic imaging. Therefore, the main imaging order with main imaging order ID: b does not have a secondary imaging order, and the maximum number of images specified for the main imaging order is 1,000. Therefore, the radiographic imaging device 10 sets the main imaging order ID: b based on the RIS code transmitted from the RIS 30. Then, the radiographic imaging device 10 performs dynamic imaging to capture one dynamic image in accordance with the main imaging order with main imaging order ID: b, and stores the captured dynamic image in association with the main imaging order ID: b.

[0057] As shown in FIG. 5, the main imaging order ID corresponding to RIS code C is c. The imaging corresponding to main imaging order ID: c is intermittent imaging. Therefore, the main imaging order with main imaging order ID: c has a secondary imaging order, and the specified maximum number of images per main imaging order is 1,000. Therefore, the radiographic imaging device 10 sets the main imaging order ID: c based on the RIS code transmitted from the RIS 30, and further sets secondary imaging order IDs: c-1 to cn. n is the number of secondary imaging orders, and increases or decreases depending on the preset number of imaging operations or the number of times the user repeats imaging, as described in FIG. 6. Then, the radiographic imaging device 10 performs intermittent imaging (still image imaging or dynamic imaging) corresponding to each of the secondary imaging orders with secondary imaging order IDs: c-1 to cn, and stores the captured images associated with the secondary imaging order IDs: c-1 to cn, respectively.

[0058] Note that the main imaging order with the main imaging order ID: c has multiple sub imaging orders, so in addition to the specified maximum number of images for the main imaging order, the specified maximum number of images for each of the multiple sub imaging orders may also be set.

[0059] In this way, the primary imaging order with primary imaging order ID: c has secondary imaging orders with secondary imaging order IDs: c-1 to cn, and corresponding images are linked to each of the secondary imaging order IDs: c-1 to cn. Therefore, the radiographic imaging device 10 processes the images linked to each of the secondary imaging order IDs: c-1 to cn as a series of images linked to the primary imaging order ID: c of one primary imaging order, and outputs them to an external device such as a PACS 40. The external device such as a PACS 40 also processes (manages, displays, analyzes, etc.) the images linked to each of the secondary imaging order IDs: c-1 to cn as a series of images linked to the primary imaging order ID: c of one primary imaging order.

[0060] Therefore, in this embodiment, secondary imaging order IDs: c-1 to cn are set in correspondence with the primary imaging order ID: c, and the images corresponding to each are linked, which makes subsequent processing easier and improves operability.

[0061] [Radiation image capturing method using a radiation image capturing device] A radiographic image capturing method carried out in the radiographic image capturing apparatus 10 will be described with reference to Fig. 6 as well as Figs. 1 to 5. Fig. 6 is a flowchart illustrating the radiographic image capturing method carried out in the radiographic image capturing apparatus 10. The radiographic image capturing method is carried out by the control unit 101 executing a radiographic image capturing program stored in the storage unit 104.

[0062] (Step S11) The control unit 101 receives an examination order including a RIS code from the RIS 30. As described above, the examination order is issued by the RIS 30. The issued examination order is then transmitted from the RIS 30 to the control unit 101 via the communication network N, the AP 20, and the second communication unit 105b, and is stored in the examination order information storage unit 104a.

[0063] (Step S12) The control unit 101 sets the main imaging order based on the RIS code. Here, a case will be described where the RIS code is C, so the main imaging order ID: c is set as the main imaging order.

[0064] (Step S13) When the main imaging order (main imaging order ID: c) is selected by a user operation, the control unit 101 transitions to an imaging operation screen, for example, a screen G11 shown in Fig. 7, which will be described later.

[0065] (Step S14) The control unit 101 checks whether there is a preset for the secondary imaging order. A code corresponding to a preset is, for example, included in the RIS code as described above, and the control unit 101 checks whether there is a preset by referring to the RIS code. Note that the RIS code does not have to include a code corresponding to a preset. In this case, the control unit 101 checks whether there is a preset by referring to the preset setting on the radiographic imaging device 10 linked to the primary imaging order. As described above, if there is no preset (NO), the control unit 101 proceeds to step S15, and if there is a preset (YES), the control unit 101 proceeds to step S18.

[0066] (Step S15) If it is determined in step S14 that there is no preset (NO), the control unit 101 displays the main imaging order in the list area (see FIG. 9, which will be described later). In this example, the main imaging order ID is c, so the main imaging order ID: c is displayed in the list area, as shown on screen G11 in FIG.

[0067] (Step S16) When imaging is performed by a user operation, the control unit 101 adds the secondary imaging order to the list area, associates the secondary imaging order with the captured image, and stores the image in the image storage unit 104b. For example, as shown on screen G12 in FIG. 7, the control unit 101 adds secondary imaging order ID: c-1 to the list area and associates the secondary imaging order ID: c-1 with the captured still image. At this time, the control unit 101 starts intermittent imaging by turning on the exposure switch 102a, and ends intermittent imaging by turning off the exposure switch 102a. Selection between still image imaging and dynamic imaging during intermittent imaging can be performed, for example, by quickly pressing or long-pressing the exposure switch 102a.

[0068] The secondary imaging order may be added at the start of, during, or end of intermittent imaging, or after intermittent imaging has ended and all images have been received by the first communication unit 105a.

[0069] (Step S17) The control unit 101 checks whether the next imaging is to be performed. For example, the control unit 101 monitors the exposure switch 102a for a predetermined time, and if the exposure switch 102a is turned on, determines that the next imaging is to be performed, and if the exposure switch 102a is not turned on, determines that the next imaging is not to be performed. If the next imaging is to be performed (YES), the process returns to step S16, and if the next imaging is not to be performed (NO), the series of processes ends.

[0070] The control unit 101 repeats steps S16 and S17 with an imaging suspension period in between until it determines that the next imaging will not be performed. For example, as shown on screens G13 and G14 in Fig. 7, the secondary imaging order IDs: c-2 and c-3 are added to the list area in order, and the secondary imaging order IDs: c-2 and c-3 are associated with the dynamic images captured by the respective secondary imaging orders and stored in the image storage unit 104b.

[0071] (Step S18) If it is determined in step S14 that there is a preset (YES), the control unit 101 displays the preset number of secondary imaging orders together with the main imaging order in the list area. In this example, the main imaging order ID is c and the secondary imaging order IDs are c-1 to c-3, so the main imaging order ID: c and the secondary imaging order IDs: c-1 to c-3 are displayed in the list area as shown on screen G21 in Fig. 8, which will be described later.

[0072] (Step S19) When imaging is performed by a user operation, the control unit 101 associates the corresponding secondary imaging order with the captured image and stores the image in the image storage unit 104b. For example, in the case of the first secondary imaging order, the secondary imaging order ID: c-1 is associated with the captured still image as shown on screen G22 in Fig. 8.

[0073] (Step S20) The control unit 101 checks whether the preset number of intermittent shootings has been completed. If the preset number of intermittent shootings has been completed (YES), the process ends, and if the preset number of intermittent shootings has not been completed (NO), the process returns to step S19.

[0074] The control unit 101 repeats steps S19 and S20 with an interval between captures until the preset number of intermittent captures is completed. For example, if there are second and third secondary capture orders, the secondary capture order IDs c-2 and c-3 are linked to the dynamic images captured by the respective secondary capture orders and stored in the image storage unit 104b, as shown on screens G23 and G24 in Fig. 8.

[0075] As described above, in this embodiment, when multiple imaging operations are performed on a patient within one operation period for one main imaging order, the main imaging order ID of the main imaging order is associated with the secondary imaging order IDs of the multiple secondary imaging orders and stored. Furthermore, the secondary imaging order IDs of the multiple secondary imaging orders are associated with the images captured for each secondary imaging order and stored. This allows the images associated with the secondary imaging order IDs of the multiple secondary imaging orders to be processed (managed, displayed, analyzed, etc.) as a series of images associated with the main imaging order ID of one main imaging order.

[0076] This embodiment is particularly suitable for cases where the number of imaging times varies, for example, when the number of imaging times during one operation period is changed depending on the status of treatment or the condition of the patient.

[0077] Here, the case where there is no preset secondary imaging order will be described with respect to the radiographic imaging method shown in Fig. 6. Fig. 7 is a diagram for schematically explaining the radiographic imaging method shown in Fig. 6, and is a diagram for explaining the case where there is no preset secondary imaging order. The diagram shown in Fig. 7 corresponds to steps S15 to S17 in the radiographic imaging method shown in Fig. 6.

[0078] If there is no preset secondary imaging order, the control unit 101 displays a screen G11 on the display unit 103, and displays the main imaging order ID: c in the list area.

[0079] A user operation starts one operation period for one main imaging order. The operation starts, for example, when the main imaging order (intermittent imaging) is selected, the radiation source 2 and the FPD 3 both become ready, and the control unit 101 permits radiation irradiation. Furthermore, the user turns on the exposure switch 102a to start intermittent imaging, and turns off the exposure switch 102a to end intermittent imaging.

[0080] In the first secondary imaging order with the secondary imaging order ID: c-1, for example, still image capture is performed for positioning. In this case, as shown on the screen G12, the control unit 101 displays the secondary imaging order ID: c-1 in the list area. Still image capture does not have to be performed if not necessary, and may be performed multiple times if necessary.

[0081] Then, the control unit 101 associates the secondary radiography order ID: c-1 added to the list area with the captured still image (here, frame image 1), and stores the still image in the image storage unit 104b. Furthermore, the control unit 101 displays the still image (frame image 1) in the image area (see FIG. 9, which will be described later), as shown on screen G12.

[0082] After this, the imaging is suspended until the user turns on the exposure switch 102a next time.

[0083] Next, suppose that the user turns on and off the exposure switch 102a, and, for example, dynamic radiography is performed. In this case, as shown on screen G13, the control unit 101 displays secondary radiography order ID: c-2 in the list area. Then, the secondary radiography order ID: c-2 added to the list area is linked to the captured dynamic images (here, frame images 2 to 8), and the linked images are stored in the image storage unit 104b. Furthermore, as shown on screen G13, the control unit 101 displays the dynamic images (frame images 2 to 8) in the image area.

[0084] Thereafter, the imaging suspension period continues until the user turns on the exposure switch 102a again, and the next imaging is performed when the user turns on and off the exposure switch 102a (see screen G14). On the other hand, the operation ends when, for example, it becomes impossible to add a secondary imaging order or the user performs an end operation.

[0085] 7, while each secondary imaging order is being executed, the user can visually recognize the secondary imaging order being executed as shown in the list area of ​​screens G12 to G14. For example, in the list area, the color of the area of ​​the secondary imaging order being executed may be made different from that of the other areas, or the area may be made to blink. Furthermore, the frame number and the number of frames captured may be displayed in the screen area.

[0086] Next, the case where a secondary imaging order is preset will be described with respect to the radiographic imaging method shown in Fig. 6. Fig. 8 is a diagram for schematically explaining the radiographic imaging method shown in Fig. 6, and is a diagram for explaining the case where a secondary imaging order is preset. The diagram shown in Fig. 8 corresponds to steps S18 to S20 in the radiographic imaging method shown in Fig. 6.

[0087] If there is a preset secondary imaging order, the control unit 101 displays a screen G21 on the display unit 103, and displays the secondary imaging order IDs c-1 to c-3 of the preset secondary imaging orders together with the main imaging order ID c in the list area.

[0088] A single operation period for one main imaging order is started by a user operation, and the user then turns on the exposure switch 102a to start intermittent imaging, and turns off the exposure switch 102a to end the intermittent imaging.

[0089] For example, in the first secondary radiography order with the secondary radiography order ID: c-1, a still image is captured for positioning. The control unit 101 associates the secondary radiography order ID: c-1 with the captured still image (here, frame image 1), and stores the still image in the image storage unit 104b. The control unit 101 also displays the still image (frame image 1) in the image area, as shown on screen G22.

[0090] After this, the imaging is suspended until the user turns on the exposure switch 102a next time.

[0091] Next, suppose that the user turns on and off the exposure switch 102a, and, for example, dynamic imaging is performed. In this case, as shown on screen G23, the control unit 101 associates the secondary imaging order ID: c-2 with the captured dynamic images (here, frame images 2 to 8), and stores them in the image storage unit 104b. Furthermore, as shown on screen G23, the control unit 101 displays the dynamic images (frame images 2 to 8) in the image area.

[0092] Thereafter, the imaging suspension period continues until the user turns on the exposure switch 102a, and the next imaging is performed by the user turning on and off the exposure switch 102a (see screen G24). On the other hand, for example, when the imaging of the preset secondary imaging orders is completed or the user performs an end operation, the operation ends at that timing.

[0093] In the example shown in FIG. 8, similarly to the example shown in FIG. 7, the user can visually confirm the secondary imaging orders being executed as shown on screens G22 to G24 while each secondary imaging order is being executed.

[0094] Furthermore, the user may be able to visually distinguish between the main and secondary imaging orders displayed in the list area. FIG. 9 shows an example of a display for distinguishing between the main and secondary imaging orders. For example, as shown in FIG. 9, the main and secondary imaging orders in the list area may be displayed with different sizes, fill patterns, colors, shapes, etc., to allow the user to visually distinguish between them. This can be achieved by the control unit 101 controlling the display unit 103.

[0095] For example, the size of the secondary imaging order area may be made smaller than that of the primary imaging order, allowing the user to distinguish between them. Alternatively, the fill pattern of the secondary imaging order area may be made coarser than that of the primary imaging order, allowing the user to distinguish between them. Alternatively, the primary and secondary imaging order areas may be made different colors, allowing the user to distinguish between them. Alternatively, the primary and secondary imaging order areas may be made different shapes, allowing the user to distinguish between them.

[0096] Furthermore, lines may be used to display a tree structure in which secondary imaging orders are connected to the primary imaging order, allowing the user to distinguish between them.

[0097] Furthermore, like the fold-down display function of well-known spreadsheet software, all or some of the secondary imaging orders may be temporarily hidden, and only the primary imaging orders, or only the primary imaging orders and necessary secondary imaging orders, may be displayed. For example, secondary imaging orders that do not need to be displayed at all times, such as still images for positioning checks, may be temporarily hidden.

[0098] In this way, the user can distinguish between the main imaging order and the secondary imaging order, so that the user can operate the device without deteriorating operability.

[0099] [Output data from radiographic imaging device] As described above, in this embodiment, one main imaging order has a plurality of sub-imaging orders, and the corresponding images are linked to each of the plurality of sub-imaging orders and stored in the image storage unit 104b.

[0100] In this way, in this embodiment, one main imaging order is linked not to one image (still image or dynamic image) taken in one imaging session, but to multiple images (multiple images including one or both of still images and dynamic images) taken in multiple imaging sessions.

[0101] Therefore, as shown in FIGS. 10 and 11, the control unit 101 outputs a plurality of images by combining them together, or outputs a plurality of images individually, and transmits them to an external device such as a PACS.

[0102] Fig. 10 is a diagram illustrating an example in which captured images of multiple secondary imaging orders of a primary imaging order are combined into one and output to an external device. Fig. 11 is a diagram illustrating an example in which captured images of multiple secondary imaging orders of a primary imaging order are individually output to an external device.

[0103] For example, in FIGS. 10 and 11, it is assumed that a still image is associated with secondary imaging order ID: c-1, and dynamic images are associated with secondary imaging order IDs: c-2 and c-3.

[0104] In the example shown in FIG. 10, the control unit 101 creates combined data by combining a still image associated with secondary imaging order ID: c-1 and dynamic images associated with secondary imaging order IDs: c-2 and c-3. In other words, the combined data becomes a multi-frame image. Then, the control unit 101 transmits the created combined data as output data corresponding to primary imaging order ID: c to an external device such as a PACS for each primary imaging order ID. At this time, the combined data is associated with information similar to that of a DICOM (Digital Image and Communications in Medicine) image (e.g., patient information, examination information, etc.). Therefore, the external device such as a PACS can treat the combined data in substantially the same way as a conventional single dynamic image.

[0105] On the other hand, in the example shown in FIG. 11 , the control unit 101 keeps the still images associated with secondary imaging order ID: c-1 and the dynamic images associated with secondary imaging order IDs: c-2 and c-3 as separate individual data. The still images remain single-frame images, and the dynamic images remain multi-frame images. The control unit 101 then transmits the individual data as output data corresponding to the primary imaging order ID: c to an external device such as a PACS for each secondary imaging order ID. At this time, the individual data is associated with the same information as a DICOM image, and is further associated with series information indicating that the data belongs to the same primary imaging order ID: c. Although the external device such as a PACS would treat the individual data as a single still image and a single dynamic image in the past, because the data is associated with series information indicating that the data belongs to the same primary imaging order ID: c, it can be treated as data from a single primary imaging order.

[0106] <Modification> In the radiographic imaging method shown in Fig. 6, adding a secondary imaging order is not prohibited, but when multiple imaging sessions are performed at a doctor's rounds rather than in an imaging room in the hospital, adding a secondary imaging order may be prohibited from the perspective of radiation exposure management. Such a case will be described with reference to Fig. 12.

[0107] 12 is a flowchart illustrating a radiographic imaging method including a determination as to whether additional imaging is possible, which is performed in a radiographic imaging device. Note that the explanation here also applies to the case where the RIS code is C. In addition, the explanation here is based on the assumption that there is no preset sub-imaging order.

[0108] (Steps S31 to S33) Steps S31 to S33 are the same as steps S11 to S13 described in the flowchart shown in FIG. 6, and therefore their description will be omitted here.

[0109] As described above, this is based on the assumption that there are no preset secondary imaging orders, but it may be determined whether there are preset secondary imaging orders as explained in step S14 of the flowchart shown in Fig. 6. If there are preset secondary imaging orders, and if an additional secondary imaging order is to be added in addition to the preset secondary imaging orders, the following determination as to whether additional imaging orders can be added may be made.

[0110] (Step S34) The control unit 101 checks whether the number of frames captured in the currently executed main imaging order has reached the specified maximum number. The control unit 101 manages the number of frames captured and the specified maximum number, for example, in a management table. If the number of frames captured has reached the specified maximum number (YES), the process proceeds to step S39. If the number of frames captured has not reached the specified maximum number (NO), the process proceeds to step S35.

[0111] (Step S35) If it is determined in step S34 that the number of captured frames has not reached the specified maximum number (NO), the control unit 101 permits the capture of the secondary imaging order. If the process proceeds to step S35 after returning from step S38 to step S34, the control unit 101 permits the capture of the additional secondary imaging order.

[0112] (Steps S36 to S38) Steps S36 to S38 are the same as steps S15 to S17 described in the flowchart of Fig. 6, and therefore their description will be omitted here. However, if the next shooting is to be performed (YES) in step S38, the process returns to step S34, and it is checked whether the number of frames shot has reached the specified maximum number.

[0113] (Step S39) If it is determined in step S34 that the number of captured frames has reached the specified maximum number (YES), the control unit 101 rejects the capture of the secondary imaging order.

[0114] (Step S40) The control unit 101, for example, displays an error message on the display unit 103, does not add a secondary imaging order, and ends the series of processes.

[0115] As described above, in this modification, it is possible to manage the radiation exposure of patients by determining whether or not a secondary imaging order can be added and prohibiting the addition of a secondary imaging order.

[0116] If it is determined that the number of captured frames has reached the specified maximum number, the control unit 101 will refuse to capture the secondary imaging order under the primary imaging order and will not add any secondary imaging orders, but may generate a new primary imaging order depending on the conditions. In this case, the new primary imaging order may allow the secondary imaging order to be captured.

[0117] Here, examples of whether additional imaging is possible will be described with reference to Figs. 13 to 15. Fig. 13 is a diagram schematically explaining an example of when additional imaging is not possible for a secondary imaging order. Fig. 14 is a diagram schematically explaining an example of when additional imaging is possible when a captured image of a secondary imaging order is a mis-image. Fig. 15 is a diagram schematically explaining an example of when additional imaging is possible when a captured image of a main imaging order is a mis-image.

[0118] In the example shown in FIG. 13, secondary imaging orders with secondary imaging order IDs: c-1 and c-2 are executed for a primary imaging order with primary imaging order ID: c. Then, assume that the number of frames captured for the secondary imaging order with secondary imaging order ID: c-2 reaches the specified maximum number (see screen G31). In this case, an error message may be displayed on screen G31. However, when the user attempts to perform the next imaging, an error message may be displayed by displaying a mark (e.g., a black x mark) indicating that addition is not possible on the secondary imaging order with secondary imaging order ID: c-3, as shown on screen G32. In this case, the control unit 101 temporarily displays secondary imaging order ID: c-3 in the list area, but rejects the addition of the secondary imaging order with secondary imaging order ID: c-3. In other words, the additional imaging is rejected, and a secondary imaging order ID: c-3 linked to the primary imaging order ID: c is not created.

[0119] 13, the control unit 101 rejects the addition of a secondary imaging order to a primary imaging order with a primary imaging order ID: c, but may generate a new primary imaging order with a primary imaging order ID: c1 under certain conditions, as shown on screen G33. In this case, the addition and imaging of a secondary imaging order with a secondary imaging order ID: c1-1 may be permitted for the new primary imaging order with a primary imaging order ID: c1.

[0120] 13, for example, when the number of captured frames reaches the specified maximum number in the secondary imaging order with secondary imaging order ID: c-1, an error message may be displayed at that time or on the next secondary imaging order c-2. In this case, the control unit 101 also temporarily displays the secondary imaging order ID: c-2 in the list area, but does not create a secondary imaging order ID: c-2 linked to the main imaging order ID: c.

[0121] In the example shown in FIG. 14, secondary imaging orders with secondary imaging order IDs: c-1 and c-2 are executed for a primary imaging order with primary imaging order ID: c. Then, assume that the secondary imaging order with secondary imaging order ID: c-2 has an imaging error due to, for example, a missing target region or body movement (see screens G41 and G42). In this case, as shown on screen G42, a mark indicating an imaging error (e.g., a white x mark) is displayed on the secondary imaging order with ID: c-2 with an imaging error. If the number of frames captured, including the secondary imaging order with secondary imaging order ID: c-2 with an imaging error, has not reached the specified maximum number, the control unit 101 permits the addition of a new secondary imaging order with secondary imaging order ID: c-2. In other words, the additional imaging is permitted, and a new secondary imaging order with ID: c-2 linked to the primary imaging order ID: c is created.

[0122] In the example shown in FIG. 15, secondary imaging orders with secondary imaging order IDs: c-1 and c-2 are executed for a primary imaging order with primary imaging order ID: c. Assume that all secondary imaging orders (secondary imaging order IDs: c-1 and c-2) linked to the primary imaging order with primary imaging order ID: c have failed imaging (see screens G51 and G52). In this case, as shown on screen G52, a mark indicating a failed imaging (e.g., a white x mark) is displayed on the primary imaging order with ID: c and the secondary imaging orders with IDs: c-1 and c-2. If the number of frames captured, including the secondary imaging orders with secondary imaging order IDs: c-1 and c-2 that have failed imaging, has not reached the specified maximum number, the control unit 101 permits a new primary imaging order with primary imaging order ID: c1. In this case, a new secondary imaging order ID: c1-1 linked to the main imaging order ID: c1 is also permitted, and a new secondary imaging order ID: c1-1 linked to the main imaging order ID: c1 is created.

[0123] As described above, in this modified example, whether or not additional imaging is possible, that is, whether or not a secondary imaging order can be added, is determined depending on whether or not the number of captured frames has reached the specified maximum number.

[0124] Instead of the specified maximum number, the following determination may be made as to whether additional imaging is possible (whether a secondary imaging order can be added).

[0125] (Judgment pattern 1) If the number of frames captured from the start of one operation period for one primary imaging order reaches a predetermined number that is smaller than the specified maximum number, additional imaging (addition of a secondary imaging order) is rejected. For example, if the specified maximum number is 1,000, the predetermined number is set to 990, which is smaller than that. This prevents unnecessary exposure of the patient to radiation when additional imaging is interrupted if the remaining number of frames is less than the number required for dynamic imaging.

[0126] (Judgment pattern 2) If the cumulative dose of radiation irradiated since the start of one operation period for one primary imaging order reaches a predetermined amount, additional imaging (addition of a secondary imaging order) is rejected. This enables patient exposure management. The cumulative dose may be calculated based on at least one of the dose area product (DAP), calculated DAP, and incident dose calculation. Here, the calculated DAP is an area dose value calculated instead of an area dosimeter. The incident dose calculation is preferably the incident dose on the patient's surface. Furthermore, instead of the cumulative dose, the cumulative number of irradiation frames, which is the cumulative number of frames irradiated with radiation since the start of one operation period, may be used.

[0127] (Judgment pattern 3) If a predetermined time has elapsed since the start of one operation period for one main imaging order, additional imaging (addition of a secondary imaging order) is rejected. For example, the predetermined time is set to 10 minutes, during which imaging and interruption are allowed any number of times. This is suitable for cases where offset images are acquired in advance and the captured images are offset corrected. Even if offset fluctuations occur in the captured images, imaging is possible within the predetermined time within a range that does not affect image quality.

[0128] (Judgment pattern 4) If the imaging suspension period reaches the specified suspension time within one operation period for one main imaging order, additional imaging (addition of a secondary imaging order) is rejected. If the imaging suspension period becomes long, it is better to reset the FPD 3 from the viewpoint of imaging quality, so by temporarily ending the operation for one operation period and resetting the FPD 3, it is possible to maintain imaging quality.

[0129] (Judgment pattern 5) If the number of secondary imaging orders reaches a predetermined number within one operation period for one primary imaging order, additional imaging (addition of secondary imaging orders) will be rejected. It may be difficult for users to correctly grasp the imaging time and radiation dose, so by managing the number of imaging that can be performed, it becomes easier to grasp the timing for completing an operation within one operation period.

[0130] (Judgment pattern 6) If the number of frames in dynamic imaging for one secondary imaging order exceeds a specified number during one operation period for one primary imaging order, additional imaging (addition of a secondary imaging order) is rejected. The specified number may be the specified maximum number described above or a predetermined number smaller than the specified maximum number.

[0131] (Judgment pattern 7) If a user performs an end operation during one operation period for one main imaging order, additional imaging (addition of a secondary imaging order) is rejected. For example, if the user performs an end operation by pressing the switch on the FPD 3 or an end operation on the screen displayed on the display unit 103, additional imaging (addition of a secondary imaging order) is rejected.

[0132] At least one of the determination patterns described above may be used to determine whether additional imaging is possible, that is, whether a secondary imaging order can be added, thereby enabling exposure control, quality control, and the like.

[0133] The display indicating that additional imaging (addition of a secondary imaging order) is not possible is not limited to the example shown on screen G32 in Fig. 13, but may be the example shown in Fig. 16. Fig. 16 is a diagram showing a display example when additional imaging of a secondary imaging order is not possible.

[0134] For example, if there is no preset for the secondary imaging order, a message indicating that additional imaging of the secondary imaging order is not possible is displayed below the last secondary imaging order, secondary imaging order ID: c-2, using a different color or a different message (here, as an example, "Limit reached" is displayed). A warning sound or audio may be output along with this display.

[0135] If the secondary imaging order has a preset, the secondary imaging order ID: c-3, which is a secondary imaging order that cannot be added, is displayed in grayout to indicate that the secondary imaging order with ID: c-3 cannot be implemented. A warning sound or audio may be output along with this display.

[0136] In this way, the user can identify whether or not a secondary imaging order can be added, and thus the user can perform the next device operation without deteriorating operability.

[0137] The above-described embodiments are merely examples of specific embodiments for carrying out the present invention, and the technical scope of the present invention should not be construed as being limited by these embodiments. In other words, the present invention can be carried out in various forms without departing from the gist or main features thereof. [Explanation of symbols]
