Fig. 1 shows a schematic configuration of the examination system 10 according to this embodiment.

[0013] The examination system 10 includes an injection device 100 for injecting a medicinal liquid into a subject, an imaging device 200 for imaging the subject, and an information processing device 300 for generating an examination result screen. The examination system 10 also includes a RIS (Radiology Information System) 11 and a PACS (Picture Archiving and Communication System) 12. The examination system 10 also includes a HIS (Hospital Information System) 13. The injection device 100, the imaging device 200, the information processing device 300, the RIS 11, the PACS 12, and the HIS 13 are connected to each other so as to be able to communicate with each other. These may be connected by wire or wirelessly. Some of these may not be connected to each other. For example, the injection device 100 may not be connected to the imaging device 200 or the PACS 12.

[0015] The control unit 110 controls the injector 120, the display unit 140, etc., in response to signals from the input unit 130, etc. The control unit 110 can also send injection information related to the injection of the liquid medicine to the imaging device 200, the information processing device 300, the RIS 11, the PACS 12, the HIS 13, etc. Here, the injection information may include, for example, information on the injected liquid medicine (for example, the name and concentration of the liquid medicine), the injection protocol (for example, the injection speed and injection amount of the liquid medicine), the injection timing, information indicating the presence or absence of leakage of the liquid medicine, and information on side effects of the liquid medicine. The injection information may be injection information preset for the examination, or may be injection information related to the examination actually performed, or may include both of these pieces of information. The control unit 110 may also exchange a synchronization signal or the like with the imaging device 200 or the information processing device 300 to synchronize the time with the imaging device 200 or the information processing device 300. In this specification, the injection protocol and the injection timing are described separately, but the injection timing may be included in the injection protocol.

[0016] The injection unit 120 is provided with, for example, a syringe filled with a medicinal liquid, a piston drive unit that drives the piston of the syringe, an injection needle, and a tube that connects the syringe and the injection needle. The piston drive unit includes any actuator such as a motor. The control unit 110 controls the piston drive unit to drive the actuator, thereby moving the piston of the syringe forward or backward, thereby injecting or aspirating the medicinal liquid.

[0017] The syringe may be filled with the liquid medicine in advance, or may be an empty syringe into which the liquid medicine is aspirated. A plurality of syringes may be provided according to the liquid medicine used in the test. The syringe may be provided with a data carrier storing information about the syringe (e.g., identification information, pressure resistance information, inner diameter, stroke length, etc.) and information about the liquid medicine (e.g., product name, concentration, ingredient information, expiration date, liquid medicine volume, etc.). As the data carrier, for example, an IC tag such as an RFID (Radio Frequency Identification) RF tag, or a barcode, etc. may be used. In this case, a sensor for detecting the data carrier may be provided in the injection device 100, and the control unit 110 may acquire the information contained in the data carrier from the sensor.

[0018] Input unit 130 can be configured using any input device, such as a button, a mouse, a keyboard, a touch panel, etc. An operator can use input unit 130 to input instructions to injection device 100, such as the above-mentioned injection information, etc.

[0019] The display unit 140 may be configured using any monitor, and can display information on medicinal liquids, injection protocols, patient information, warnings, etc., under the control of the control unit 110. The display unit 140 may be configured as a touch panel display, and the input unit 130 and the display unit 140 may be configured integrally.

[0020] Storage unit 150 can store programs for implementing various functions of injection device 100, various injection information, information on the syringe and medicinal liquid attached to injection unit 120, patient information, etc. Storage unit 150 may be configured using any memory, optical disk, or storage medium.

[0021] The leak detection unit 160 includes a sensor that detects leakage of the injected medicinal liquid. When leakage of the medicinal liquid is detected by the sensor, the leak detection unit 160 can send information indicating the leakage to the control unit 110 and the storage unit 150. Note that the leak detection unit 160 may detect leakage of the injected medicinal liquid based on an image acquired using a camera or the like.

[0022] The control unit 110 may be configured using any computer including a processor, such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit), and a memory. The processor may be a GPU (Graphic Processing Unit). Furthermore, the various functions of the control unit 110 may be realized as software modules executed by the processor. Furthermore, the various functions of the control unit 110 may be realized using circuits, such as an FPGA (Field Programmable Gate Array) or an ASIC (Application Specific Integrated Circuit).

[0023] The imaging device 200 is an imaging device that images a subject when performing an examination, and may be, for example, a radiation imaging device, a CT device, an MRI device, a PET device, an ultrasonic diagnostic device, an angiography imaging device, or the like. In this embodiment, a configuration using an X-ray imaging device as the imaging device 200 will be described. However, the imaging device 200 may be configured using any of the imaging devices described above depending on a desired configuration.

[0024] The imaging device 200 includes a control unit 210, an imaging unit 220, an input unit 230, a display unit 240, and a storage unit 250. The control unit 210 controls the imaging unit 220, the display unit 240, and the like in response to signals from the input unit 230 and the like. The control unit 210 can generate (reconstruct) an image based on imaging data output by the imaging unit 220, and perform predetermined image processing. The control unit 210 can send imaging information related to imaging, a planned imaging time, and the like to the information processing device 300, the RIS 11, the PACS 12, the HIS 13, and the like. Here, the imaging information may include, for example, an imaging execution time indicating the time when imaging was performed, an imaged image, an index related to imaging indicating, for example, a radiation dose or a voltage applied to a generation source, and information indicating an imaging site. Note that the index related to imaging and the information on an imaging site included in the imaging information may be information set in advance for an examination, or may be information related to an actually performed examination. Furthermore, control unit 210 may exchange a synchronization signal or the like with injection device 100 and information processing device 300 to synchronize the time with injection device 100 and information processing device 300 .

[0025] Furthermore, the control unit 210 calculates the planned imaging time based on the injection information, the imaging site, the patient's biological information, and the like acquired from the injection device 100. For example, the control unit 210 calculates the planned imaging time from the start of injection at which the CT value at the imaging site is about 400 HU required for a contrast image, for example, between 350 HU and 450 HU. The control unit 210 may calculate the planned imaging time using any known contrast agent simulator, or may calculate the planned imaging time using the results of a test injection or the like performed based on an injection protocol. Furthermore, the control unit 210 may calculate the planned imaging time using a bolus tracking method or the like. Note that the pixel value (CT value) or the like that is the target when calculating the planned imaging time may be appropriately changed according to the desired configuration.

[0026] The imaging unit 220 may be configured using a member for imaging the subject according to the type of the imaging device 200. The imaging unit 220 may be configured using, for example, a generator for generating radiation, magnetism, ultrasound, etc. used in imaging the subject, and a detector for detecting radiation, nuclear magnetic resonance signals, ultrasound, etc. In addition, in a PET device or the like, the imaging unit 220 may be configured without using a generator. In addition, in an ultrasound diagnostic device, a transducer may be used as the generator and detector. In this embodiment, the imaging unit 220 is configured using a radiation generator and a radiation detector. The imaging unit 220 performs imaging of the subject according to the control by the control unit 210, and can output imaging data corresponding to the detected radiation, ultrasound, etc. to the control unit 210 or the storage unit 250. Here, the imaging unit 220 can obtain three-dimensional data or two-dimensional data of the subject as imaging data according to the imaging conditions.

[0027] The input unit 230 can be configured using any input device, such as a button, a mouse, a keyboard, a touch panel, etc. By using the input unit 230, the operator can input instructions to the imaging device 200 regarding the timing of imaging for the examination, the radiation dose, etc.

[0028] The display unit 240 may be configured using any monitor, and can display the generated image, imaging information related to imaging, patient information, warnings, etc., under the control of the control unit 210. The display unit 240 may be configured as a touch panel display, and the input unit 230 and the display unit 240 may be configured integrally.

[0029] The storage unit 250 can store programs for implementing various functions in the imaging device 200, imaging execution time indicating the time when imaging was performed, indices related to imaging such as the amount of radiation and the amount of voltage applied to the generator, patient information, etc. The storage unit 250 may be configured using any memory, optical disk, or storage medium.

[0030] The control unit 210 may be configured using any computer including a processor such as a CPU, MPU, or GPU, and a memory. Furthermore, the various functions of the control unit 210 may be realized as software modules executed by a processor. Furthermore, the various functions of the control unit 210 may be realized using a circuit such as an FPGA or ASIC.

[0031] The information processing device 300 judges whether the contrast agent is successful or not based on the imaging information, and generates an examination result screen showing the injection information, the planned imaging time, the imaging information, and the result of the contrast agent success or not judgment. In particular, in this embodiment, the information processing device 300 judges whether the contrast agent is successful or not based on the captured image included in the imaging information. The information processing device 300 is provided with a control unit 310, an input unit 320, a display unit 330, and a storage unit 340.

[0032] Control unit 310 generates an examination result image showing the result of the determination of the success or failure of the contrast agent in response to a signal from input unit 320, injection information, planned imaging time, imaging information, etc. Control unit 310 may also exchange a synchronization signal or the like with injection device 100 and imaging device 200 to synchronize the time with injection device 100 and imaging device 200. Control unit 310 is provided with an acquisition unit 311, a determination unit 312, a generation unit 313, and an output unit 314.

[0033] Acquiring unit 311 acquires injection information including information on the injected drug and the executed injection protocol from injection device 100. Acquiring unit 311 also acquires imaging information related to executed imaging, such as the captured image and the imaging execution time, and the scheduled imaging time from imaging device 200. Note that in this embodiment, a configuration in which acquiring unit 311 acquires injection information, imaging information, and the like from injection device 100 and imaging device 200 will be described, but acquiring unit 311 may acquire this information from RIS 11, PACS 12, HIS 13, or other information processing devices, etc.

[0034] Acquiring unit 311 may also acquire injection information such as an injection protocol, imaging information such as imaging execution time, and planned imaging time in response to an operator's operation of input unit 320. Furthermore, acquiring unit 311 may acquire operation information of injection device 100 and imaging device 200, such as operation sounds and images of these devices, using a microphone, camera, etc. (not shown), and acquire information on the injection timing and imaging execution time based on the acquired operation information. In this case, the microphone, camera, etc. may be located away from information processing device 300, and may be located, for example, in the same room as the device from which the operation information is acquired.

[0035] The acquired injection information such as the drug solution and the injection protocol, and the imaging information such as the indexes related to imaging may be information preset for the examination, or may be information related to the actually performed examination. The acquisition unit 311 may acquire both the information preset for the examination and the information related to the actually performed examination.

[0036] The determination unit 312 determines whether the contrast enhancement is successful or not based on the captured image included in the imaging information acquired by the acquisition unit 311. More specifically, in this embodiment, the determination unit 312 determines whether or not a pixel value at a pixel position according to an instruction from an operator is within a predetermined range for a representative two-dimensional image based on the captured image of the subject. If the pixel value is within the predetermined range, the determination unit 312 determines that the contrast enhancement is successful, and if the pixel value is not within the predetermined range, the determination unit 312 determines that the contrast enhancement is unsuccessful.

[0037] However, the method of determining whether or not contrast enhancement has been achieved is not limited to this. For example, the determination unit 312 may perform the determination based on any two-dimensional image included in the three-dimensional captured image, or may perform the determination based on the captured two-dimensional captured image.

[0038] In addition, the pixel position of the pixel value used for the judgment may be a predetermined pixel position or multiple pixel positions. When pixel values ​​of multiple pixel positions are used, the judgment unit 312 may judge whether each pixel value is within a predetermined range or whether the median value, average value, etc. of the pixel values ​​of the multiple pixel positions is within a predetermined range.

[0039] The generating unit 313 projects the three-dimensional captured image in a predetermined range to generate the representative two-dimensional image. For example, maximum value projection or average projection may be used as a method for generating the representative two-dimensional image, or a projection method in which the median value of data in a predetermined range is used as a representative value may be used. The representative two-dimensional image may also be generated by accumulating the three-dimensional captured image in a predetermined range.

[0040] Furthermore, the generating unit 313 generates an examination result screen showing the injection information, the scheduled imaging time, imaging information including the captured image, and the result of the determination made by the determining unit 312. The examination result screen will be described later in detail.

[0041] Output unit 314 outputs the examination result screen generated by generation unit 313. For example, output unit 314 displays the examination result screen on display unit 330. In this case, output unit 314 functions as an example of a display control unit that controls the display of display unit 330. Furthermore, output unit 314 may output the examination result screen to other devices such as RIS 11, PACS 12, HIS 13, injection device 100, imaging device 200, etc., or may output it to any storage device such as a server. Furthermore, output unit 314 may output the examination result screen to storage unit 340.

[0042] The input unit 320 can be configured using any input device, such as a button, a mouse, a keyboard, a touch panel, etc. An operator can input instructions to the information processing device 300 by using the input unit 320.

[0043] The display unit 330 may be configured using any monitor, and can display the generated examination result screen, imaging information related to imaging, patient information, warnings, etc., under the control of the control unit 310. The display unit 330 may be configured as a touch panel display, and the input unit 320 and the display unit 330 may be configured integrally.

[0044] The storage unit 340 can store programs for implementing various functions in the information processing device 300, generated inspection result images and representative two-dimensional images, and judgment results by the judgment unit 312. The storage unit 340 may be configured using any memory, optical disk, or storage medium.

[0045] The control unit 310 may be configured using any computer including a processor such as a CPU, MPU, or GPU, and a memory. Furthermore, the various functions of the control unit 310 may be realized as software modules executed by a processor. Furthermore, the various functions of the control unit 310 may be realized using a circuit such as an FPGA or ASIC. The information processing device 300 may be configured as, for example, a server that generates an examination result screen based on injection information, etc., or may be configured as a workstation, etc.

[0046] Next, a series of processes according to this embodiment will be described with reference to Fig. 2. Fig. 2 is a flowchart of a series of processes according to this embodiment. When a series of processes according to this embodiment is started, the process proceeds to step S210.

[0047] In step S210, acquisition unit 311 acquires injection information from injection device 100, and acquires imaging information and scheduled imaging time from imaging device 200. However, acquisition unit 311 may acquire these from RIS 11, PACS 12, HIS 13, or the like.

[0048] In step S220, the determination unit 312 determines whether or not contrast enhancement is successful based on the captured image included in the imaging information obtained by the acquisition unit 311. In this embodiment, the generation unit 313 projects the three-dimensional captured image within a predetermined range to generate a representative two-dimensional image. The determination unit 312 determines whether or not a pixel value at a pixel position according to an instruction from an operator is within a predetermined range for the generated two-dimensional image.

[0049] More specifically, in this embodiment, the determination unit 312 determines whether the pixel value (CT value) is around 400 HU, for example, between 350 HU and 450 HU. However, the range may be set arbitrarily depending on the desired configuration and imaging technique. Also, the range may be set for each imaging site or subject, for example. The determination unit 312 determines that the imaging was successful when the pixel value is within a predetermined range, and determines that the imaging was unsuccessful when the pixel value is not within the predetermined range.

[0050] The success or failure of the contrast enhancement may be determined for each imaging site or structure of the imaging site included in the captured image. For example, when examining the subject's heart as an imaging site, the success or failure of the contrast enhancement may be determined for each of the right atrium, left atrium, aortic valve, etc. included in the captured image. In this case, the captured image used for the determination may be an image extracted for each imaging site or structure of the imaging site.

[0051] In step S230, the generation unit 313 generates an examination result screen 400A showing the injection information, the planned imaging time, imaging information including the captured image, and the result of the judgment by the judgment unit 312. Fig. 3 shows an example of the examination result screen 400A according to this embodiment.

[0052] 3, the examination result screen 400A displays examination information 410 related to the patient and the examination, injection information 420 related to the injection of the medicinal liquid, imaging information 430 related to imaging, and a planned imaging time based on the injection information 440. The examination result screen 400A also displays examination results 450 including the captured images and the judgment results by the judgment unit 312.

[0053] Examination information 410 includes the patient's name, biological information such as the patient's sex, age, height, and weight, patient identification information (ID), examination date, etc. The above examination information is an example, and may include, for example, other biological information, examination identification information, facility name, examination room name, identification information of the device used, and identification number of the examiner. Furthermore, the examination information may be obtained from HIS 13 or the like, or may be input to injection device 100, imaging device 200, information processing device 300, etc. by the operator or a measuring device corresponding to the examination information at the time of the examination.

[0054] The injection information 420 includes information on the liquid medicine, such as the name and concentration of the medicine, and an injection protocol, such as the injection speed and injection amount of the liquid medicine. In this embodiment, the injection information 420 includes information on the contrast medium 421, information on the saline solution 422, and an amount of iodine 423. The injection information 420 may also include biological information at the time of injection, which in this embodiment includes a heart rate 424. The injection information 420 may also include information on the liquid medicine, such as the name (product name) and concentration of the contrast medium 425, information 426 indicating the presence or absence of leakage of the liquid medicine, and information 427 on side effects of the liquid medicine. The information on side effects 427 may indicate information on side effects known for each liquid medicine, or may indicate information on side effects that occurred in the patient during the examination.

[0055] The above-mentioned injection information is an example, and may include, for example, identification information of the contrast agent or saline, identification information of the device used, other biological information, etc. Furthermore, this information may be acquired by acquisition unit 311, for example, from RIS 11, HIS 13, etc. Furthermore, information 426 indicating the presence or absence of leakage of medicinal liquid may be acquired by acquisition unit 311 from injection device 100, RIS 11, HIS 13, etc. Furthermore, acquisition unit 311 may acquire this information from input unit 320 in response to an operation by the operator.

[0056] The contrast agent information 421 includes an injection rate and an injection amount of the contrast agent. The contrast agent information 421 may include other information related to the contrast agent, such as the name and concentration of the contrast agent included in the liquid medicine information 425, an iodine amount 423, and identification information of the contrast agent. Here, the iodine amount 423 may indicate the amount of iodine injected into the subject or the amount of iodine in the liquid medicine. The amount of iodine injected into the subject may be indicated, for example, as the amount of iodine per subject's weight and time (mgI / kg / sec), or the amount of iodine per subject's weight (mgI / kg). The saline solution information 422 includes an injection rate and an injection amount of saline solution.

[0057] The imaging information 430 includes an effective dose 431, a tube voltage (kVp) 432, and a site image (information on the imaging site) 433 indicating the imaging site, etc. The imaging information 430 also includes an exposure start time 434 corresponding to the imaging start time, an exposure end time 435 corresponding to the imaging end time, an imaging execution time 436, etc.

[0058] The effective dose 431 indicates a cumulative effective dose including a new effective dose (radiation exposure amount) used in the examination and effective doses in past examinations performed up to the examination. Here, the effective dose 431 may indicate only the new effective dose used in the examination. The effective dose 431 may also indicate an exposure result for a patient, or may indicate at least one of the new and cumulative exposure results. Any known index may be used as an index indicating the effective dose according to a desired configuration. For example, the index indicating the dose may be Dose Length Product (DLP), Computed Tomography Dose Index (CTDI), volume CTDI (CTDIvol), weighted CTDI (CTDIw), etc. The index indicating the dose may also be Size-Specific Dose Estimates (SSDE), Dose Area Product (DAP), fluoroscopy time, reference point dose, entrance skin peak dose, Exposure Index (EI), average milk dose, etc.

[0059] Here, the effective dose 431 and the tube voltage 432 are examples of indices related to imaging. The indices displayed on the examination result screen 400A are not limited to the effective dose 431 and the tube voltage 432, and may be any indices according to the imaging technique used in the examination. The indices may be, for example, a current-time product (mAs), a dose distribution per body weight, an exposure dose per part, a comparison result with a reference such as a DRL (Diagnostic Reference Level), etc. Similarly, the exposure start time 434 and the exposure end time 435 are examples of the start time and end time of the executed imaging, and may be the start time and end time according to the imaging technique used in the examination, respectively.

[0060] The part image 433 may be an image that shows the part to be imaged in a schematic manner, or may be an actually acquired image, etc. The part image 433 may show the location imaged at each time along the imaging execution time 436, or may simply show the part where imaging was performed. The imaging information is an example, and may include, for example, identification information of the device used, etc.

[0061] In this embodiment, the imaging execution time 436 is indicated by a bar, and the exposure start time 434 and the exposure end time 435 are indicated by the beginning and end of the bar. However, the display manner of the imaging execution time 436, the exposure start time 434, and the exposure end time 435 is not limited to this, and may be changed arbitrarily according to a desired configuration. For example, the exposure start time 434 and the exposure end time 435 may be displayed by numbers, etc., similar to the start time 441 and end time 442 of the scheduled imaging time described below.

[0062] The planned imaging time 440 indicates the planned imaging time set based on injection information such as an injection protocol along a bar of the imaging execution time 436. In this embodiment, the planned imaging time 440 includes a start time 441 of the planned imaging time, an end time 442 of the planned imaging time, and a planned peak time 443 at which the CT value (pixel value) in the imaging region reaches a peak. As described above, the planned imaging time may be calculated using any known contrast agent simulator, or may be calculated using the results of a test injection or the like performed based on an injection protocol, a bolus tracking method, or the like.

[0063] Note that the scheduled imaging time 440 is not limited to being displayed along the bar of the imaging execution time 436, and may be displayed in another manner that is easy to compare with the imaging execution time 436. In this embodiment, the start time 441 of the scheduled imaging time, the end time 442 of the scheduled imaging time, and the scheduled peak time 443 indicate each time when the injection start time is set as the reference time (0 seconds), but the reference for each time may be changed arbitrarily depending on a desired configuration.

[0064] The inspection result 450 includes a two-dimensional image 451, which is a representative image as a captured image, and a judgment result 452 in step S220. The two-dimensional image 451 may be a two-dimensional image generated in step S220. The judgment result 452 may be displayed as GOOD or the like when it is determined that the contrast enhancement is successful, or as BAD or the like when it is determined that the contrast enhancement is unsuccessful, depending on the judgment result in step S220. The inspection result 450 may also display a pixel value 453 used in the judgment in step S220. In this case, the operator can judge whether the judgment result 452 is appropriate or not based on the two-dimensional image 451 and the pixel value 453. In other words, the two-dimensional image 451 and the pixel value 453 can support the operator's judgment regarding whether the judgment result 452 is appropriate or not. Note that the above inspection result is an example, and may include, for example, a projection method of the two-dimensional image and the position of the pixel used in the judgment.

[0065] Furthermore, the image shown in the test result 450 may not be the two-dimensional image used in the judgment by the judgment unit 312. For example, the image may be an image obtained by performing a predetermined rendering process on a three-dimensional captured image of the subject including a plurality of slice images, or may be any slice image included in the three-dimensional captured image. Furthermore, the image may be, for example, a two-dimensional image generated from a three-dimensional captured image, separate from the two-dimensional image used in the judgment by the judgment unit 312. Furthermore, the image may be, for example, an image obtained by extracting and drawing a region of interest, such as a blood vessel, from the three-dimensional captured image of the subject.

[0066] In step S240, output unit 314 outputs examination result screen 400A generated in step S230. For example, output unit 314 displays examination result screen 400A on display unit 330. Output unit 314 may also output examination result screen 400A to other devices such as RIS 11, PACS 12, HIS 13, injection device 100, imaging device 200, etc., or to any storage device such as a server. Output unit 314 may also output the examination result screen to storage unit 340.

[0067] As described above, the examination system 10 according to this embodiment includes an information processing device 300, an injection device 100 that injects a medicinal liquid into a subject, and an imaging device 200 that images the subject. The information processing device 300 includes an acquisition unit 311, a determination unit 312, and a generation unit 313. The acquisition unit 311 acquires injection information related to the injection of the medicinal liquid, a planned imaging time for imaging, and imaging information related to imaging. The determination unit 312 determines whether or not the imaging is successful based on the imaging information. The generation unit 313 generates an examination result screen 400A that shows the injection information, the planned imaging time, the imaging information, and the result of the determination made by the determination unit 312.

[0068] In this embodiment, the injection information includes information on the medicinal liquid and an injection protocol, and the imaging information includes an imaging execution time when imaging was performed and an image that was captured. The determination unit 312 determines whether or not contrast enhancement is successful based on pixel values ​​of a two-dimensional image generated using a three-dimensional captured image included in the imaging information. Here, the generated two-dimensional image can be a two-dimensional image generated by projecting the three-dimensional captured image within a predetermined range. Also, the captured image displayed on the generated screen can be the two-dimensional image.

[0069] Furthermore, the information processing device 300 further includes an output unit 314 that outputs the generated screen to another device. Here, the output unit 314 can function as a display control unit that displays the generated screen on the display unit 330. Furthermore, the examination system 10 further includes at least one of a radiology information system (RIS) 11, a picture archiving and communication system (PACS) 12, and a hospital information system (HIS) 13. The output unit 314 of the information processing device 300 can output the generated screen to at least one of the RIS 11, the PACS 12, and the HIS 13.

[0070] With such a configuration, the examination system according to this embodiment can generate an examination result screen 400A that collectively shows information on the injection of the drug solution and imaging, the captured image, and the result of the determination of the success or failure of the angiography. This allows the examination system 10 to efficiently present information on the success or failure of the angiography and the performed imaging. Therefore, by using the examination system according to this embodiment, it is possible to efficiently determine the success or failure of the angiography and to efficiently identify the cause of failure.

[0071] Moreover, by outputting the generated examination result screen 400A to a storage device or the like by the output unit 314, information on the performed examination and the examination results can be efficiently accumulated. Here, information on examinations in which contrast injection has failed and the examination results are generally considered unnecessary and are often deleted. However, from the viewpoint of improving the success rate of contrast injection in future examinations, information on examinations in which contrast injection has failed and the examination results are useful for verifying injection and imaging protocols, etc. Therefore, by automatically outputting the generated examination result screen 400A to a storage device or the like by the output unit 314, information useful for verifying injection and imaging protocols, etc. can be efficiently accumulated. Here, the storage device may be, for example, a storage device included in the storage unit 340 of the information processing device 300, or a storage device included in any server such as the injection device 100, the imaging device 200, the RIS 11, the PACS 12, the HIS 13, and a cloud server.

[0072] Furthermore, in this embodiment, the judgment by the judgment unit 312 is made based on a representative two-dimensional image generated by the generation unit 313, but the information used for the judgment is not limited to this. The judgment unit 312 may make the judgment based on, for example, a three-dimensional captured image of the subject. When the judgment unit 312 makes the judgment based on a plurality of data (for example, pixel values ​​at a plurality of pixel positions), it may compare each of the plurality of data with a predetermined value serving as a threshold value, or may compare the average value or median value of the plurality of data with a predetermined value.

[0073] In addition to or instead of these judgments, the judgment unit 312 may compare, for example, the scheduled imaging time 440 and the imaging execution time 436 to judge whether the contrast enhancement is successful. For example, the judgment unit 312 may judge that the contrast enhancement is successful if the difference between the scheduled imaging time 440 and the imaging execution time 436 is equal to or less than a predetermined threshold, and may judge that the contrast enhancement is unsuccessful if the difference is greater than the predetermined threshold. In this case, the judgment result 452 may indicate a judgment result based on the timing of the imaging. Note that, when the judgment unit 312 performs both the judgment based on the pixel value (captured image) described above and the judgment based on the timing of the imaging, the judgment result 452 may indicate, for example, failure if either judgment is judged to be unsuccessful. Also, when the judgment unit 312 performs both the judgment based on the pixel value (captured image) described above and the judgment based on the timing of the imaging, the judgment result 452 may indicate, for example, a judgment result for each judgment.

[0074] The examination result screen 400A may be configured to be correctable by an operator. For example, the operator may correct the judgment result 452 by the judgment unit 312 based on the pixel value 453 included in the examination result 450, or an operator such as a medical professional who has viewed the two-dimensional image 451 may correct the judgment result 452 based on experience or intuition. In this case, the output unit 314 may switch to the examination result screen before correction and display the examination result screen after correction on the display unit 330. Furthermore, the output unit 314 may output the examination result screen after correction to the RIS 11, etc., in addition to the examination result screen before correction.

[0075] The inspection system 10 may be configured to switch the inspection result screen 400A to a screen showing details of the selected information when the operator selects various information on the inspection result screen 400A. For example, the inspection system 10 may be configured to switch the inspection result screen 400A to a screen showing an enlarged image of the two-dimensional image 451, a three-dimensional captured image related to the two-dimensional image 451, and the positions of pixels used in the judgment, when the operator selects the two-dimensional image 451. The inspection result screen 400A may be automatically displayed on the display unit 330, or may be displayed in response to an instruction from the operator. For example, the output unit 314 may display a screen on the display unit 330 that does not show the inspection result 450 or the judgment result 452, and display the inspection result screen 400A on the display unit 330 in response to an instruction from the operator, such as clicking. The output unit 314 may output a sound from a speaker (not shown) or the like when displaying the inspection result screen 400A, so that the operator can easily notice the display of the inspection result screen 400A.

[0076] Furthermore, in this embodiment, the injection information 420 and the imaging information 430 shown on the examination result screen 400A are information related to an actually performed examination. In contrast, the injection information 420 and the imaging information 430 preset for the examination may be shown on the examination result screen 400A. For example, regarding the injection information, the injection speed and injection amount of the medicinal liquid in the actually performed examination may differ from the set injection speed and injection amount due to the surrounding environment, the status of the equipment, etc. For this reason, the injection information 420 and the imaging information 430 shown on the examination result screen 400A may be displayed with distinction between the preset information and the information related to the actually performed examination. In this case, the information processing device 300 may be configured so that the information shown on the examination result screen 400A can be switched between the preset information for the examination and the information related to the actually performed examination by an arbitrary button or the like.

[0077] In this embodiment, information processing device 300 is a device that generates examination result screen 400A indicating the success or failure of contrast imaging, but the processing by information processing device 300 is not limited to this. For example, information processing device 300 may control the operation of injection device 100 and imaging device 200. In this case, information processing device 300 may input injection information and imaging information input via input unit 320 to injection device 100 and imaging device 200, and control the operation of these devices.

[0078] In this embodiment, the control unit 210 of the imaging device 200 calculates the planned imaging time, and the acquisition unit 311 acquires the planned imaging time from the imaging device 200. In response to this, the control unit 310 of the information processing device 300 may calculate and acquire the planned imaging time based on the injection information, the target pixel value (CT value), the patient's biological information, and the like. In this case, the control unit 310 may calculate the planned imaging time using any known contrast agent simulator, or may calculate it using the results of a test injection or the like performed based on an injection protocol. Furthermore, the control unit 310 may calculate the planned imaging time using a bolus tracking method or the like. In this case, the calculated planned imaging time may be sent to the imaging device 200 during an examination.

[0079] The planned imaging time may be calculated by control unit 110 of injection device 100 or another information processing device using the method described above, and sent to imaging device 200, information processing device 300, or the like. The patient's biological information used to calculate the planned imaging time may be acquired from HIS 13, or the like. In order to calculate the planned imaging time that is more suited to the patient's condition, the patient's biological information at the time of the examination input to imaging device 200, or the like, by the operator or a measuring device corresponding to the biological information, may also be acquired.

[0080] In this embodiment, the operator may input injection information such as information on the medicinal liquid, the injection protocol, the injection timing, and information on side effects of the medicinal liquid to injection device 100 via input unit 320. However, control unit 210 of imaging device 200 may calculate injection conditions such as an injection protocol including an injection rate and an injection amount based on the medicinal liquid information and the patient information, and send the calculated injection conditions to injection device 100. Control unit 210 may use any known contrast agent simulator to calculate injection conditions such that the CT value at the imaging site is about 400 HU required for a contrast image, for example, between 350 HU and 450 HU, and the duration of the CT value is a predetermined time.

[0081] Using a similar technique, control unit 110 of injection device 100 may calculate injection conditions such as an injection protocol including an injection rate and an injection amount. Using a similar technique, control unit 310 of information processing device 300 or another information processing device may calculate injection conditions such as an injection protocol including an injection rate and an injection amount and send them to injection device 100. The patient's biological information used to calculate the injection conditions may be acquired from HIS 13 or the like. In order to calculate injection conditions that are more suited to the patient's condition, the patient's biological information at the time of the examination inputted to injection device 100 or the like by an operator or a measuring device corresponding to the biological information may also be acquired.

[0082] Furthermore, in this embodiment, information processing device 300 is configured as a device separate from injection device 100 and imaging device 200. However, information processing device 300 may be configured by injection device 100 and imaging device 200. Specifically, by configuring control unit 310 of information processing device 300 by control unit 110 of injection device 100 and control unit 210 of imaging device 200, the various functions of information processing device 300 described above can be executed by injection device 100 and imaging device 200.

[0083] (Variation 1) 3 is an example, and the arrangement of the various information on the test result screen 400A according to the first embodiment may be changed as desired. In addition, some of the various information arranged on the test result screen 400A may be omitted or other information may be added according to the desired configuration.

[0084] Here, the test result screen 400B according to the first modified example of the present invention will be described with reference to FIG. 4. FIG. 4 shows an example of the test result screen 400B according to this modified example. Since the configuration of the test system according to this modified example is similar to that of the test system according to the first embodiment, the same reference numerals will be used and the description will be omitted. Furthermore, since a series of processes according to this modified example is similar to that of the first embodiment, the description will be omitted. Furthermore, in this modified example, the same information as that in the test result screen 400A according to the first embodiment will be used with the same reference numerals and the description will be omitted. Below, the test result screen 400B according to this modified example will be described, focusing on the difference from the test result screen 400A according to the first embodiment.

[0085] In the examination result screen 400B according to this modification, imaging information 430 and scheduled imaging time 440 are arranged below the injection information 420, and examination results 450 are arranged to the right of the injection information 420, imaging information 430, and scheduled imaging time 440. In addition, in the examination result screen 400B, the information on the name and concentration of the contrast agent, which is described as the information on the medicinal liquid 425 in the examination result screen 400A according to the first embodiment, is included in the information on the contrast agent 421. Furthermore, in the examination result screen 400B, in addition to the injection information 420, imaging information 430, scheduled imaging time 440, and examination results 450, remark information 460 is displayed.

[0086] Remark information 460 includes, for example, information 461 indicating the presence or absence of leakage of the medicinal liquid, and information 462 on side effects of the medicinal liquid. Like information 427 on side effects according to the first embodiment, information 462 on side effects may indicate information on side effects known for each medicinal liquid, or may indicate information on side effects that occurred in a patient during an examination. Information 462 on side effects of the medicinal liquid may be acquired by acquisition unit 311, for example, from RIS 11, HIS 13, etc. Information 461 indicating the presence or absence of leakage of the medicinal liquid may be acquired by acquisition unit 311 from injection device 100, RIS 11, HIS 13, etc. Acquisition unit 311 may acquire these pieces of information from input unit 320 in response to an operation by an operator. Note that the above remark information is an example, and may include, for example, a patient's illness, a progress of the illness, etc.

[0087] In this modification, the examination result screen 400B has been described, which has a different arrangement of various information from the examination result screen 400A. Even when such an examination result screen 400B is used, it is possible to collectively display information regarding the injection of medicinal liquid and imaging, the captured image, and the judgment result of the success or failure of imaging. Therefore, even when the examination system according to this modification is used, it is possible to efficiently judge the success or failure of imaging and to specify the cause in the case of failure. Note that the various configuration changes described in the first embodiment can also be applied to this modification as appropriate.

[0088] Example 2 In the examination system according to the second embodiment of the present invention, an examination result screen is generated that collectively displays information related to the injection of the drug solution and imaging, the planned imaging time, the captured image, and the result of the judgment of the success or failure of the contrast agent, and also displays the injection timing, the planned imaging time, and the imaging execution time along the same time axis. Hereinafter, the examination result screen 500 according to this embodiment will be described with reference to Fig. 5. Fig. 5 shows an example of the examination result screen 500 according to this embodiment.

[0089] Since the configuration of the inspection system according to this embodiment is similar to that of the inspection system according to Example 1 and Modification 1, the same reference numerals are used and the description is omitted. Furthermore, since the series of processes according to this embodiment is similar to the series of processes according to Example 1 and Modification 1, the description is omitted. Furthermore, in this embodiment, the same information as the various information on the inspection result screen 400B according to Modification 1 is used with the same reference numerals and the description is omitted. Below, the inspection result screen 500 according to this embodiment will be described, focusing on the differences from the inspection result screen 400B according to Modification 1.

[0090] The injection information according to this embodiment includes the injection timing in addition to the above-mentioned information on the injected medicinal liquid, and acquisition unit 311 acquires the injection information including the injection timing from injection device 100. In this specification, the injection protocol and the injection timing are described separately, but the injection timing may be included in the injection protocol. Note that the injection information according to this embodiment may also be injection information preset for an examination, or may be injection information related to an actually performed examination, or may include both of these pieces of information.

[0091] Moreover, the generating unit 313 according to this embodiment generates an examination result screen showing the injection information, the planned imaging time, imaging information including an image, and the result of the judgment by the judging unit 312. In particular, the generating unit 313 according to this embodiment generates an examination result screen 500 showing the injection timing, the planned imaging time, and the imaging execution time along the same time axis. As shown in Fig. 5, the examination result screen 500 shows the examination information 410, the injection information 520, the imaging information 530, the planned imaging time 540, the examination result 450, and the remarks information 460.

[0092] The injection information 520 includes information on the medicinal liquid, such as the name and concentration of the drug, an injection protocol, such as the injection rate and injection amount of the medicinal liquid, and an injection timing. The injection information 520 according to this embodiment includes information on the contrast agent 521, information on the saline solution 522, an amount of iodine 423, and a heart rate 424. The injection information 520 according to this embodiment further includes an injection start time 525 of the contrast agent, an injection end time of the contrast agent and an injection start time 526 of the saline solution, and an injection end time 527 of the saline solution. The above-mentioned injection information is an example, and may include, for example, identification information of the contrast agent and the saline solution, identification information of the device used, and other biological information.

[0093] In this embodiment, for easy visual understanding, the contrast agent information 521 and the saline information 522 are shown as rectangular regions in a graph in which the vertical axis indicates the injection speed and the horizontal axis indicates the time. Therefore, the contrast agent information 521 and the saline information 522 can indicate the injection timing of the medicinal liquid along the horizontal axis (time axis). Note that this display form is an example, and for example, the contrast agent information 521 and the saline information 522 may be displayed using a surface graph or other graphs. In addition, the injection start time 525 of the contrast agent, the injection end time of the contrast agent, the injection start time 526 of the saline, and the injection end time 527 of the saline indicate each time on the time axis. Here, in this embodiment, the injection start time 525 of the contrast agent is set as the reference time (0 sec), but any other time may be set as the reference time.

[0094] In the imaging information 530, the start and end of a bar indicating the imaging execution time 536 indicates an exposure start time 534 and an exposure end time 535. In this embodiment, the imaging execution time 536 indicates the time when imaging was actually performed along the time axis indicating the injection timing, and the exposure start time 534 and the exposure end time 535 indicate each time along the time axis indicating the injection timing. In this embodiment, only the new effective dose 531 used in the examination is indicated as the effective dose 531. However, the description of the effective dose 531 is not limited to this, and as shown in Figs. 3 and 4, a cumulative effective dose including the new effective dose and the effective dose in the past examinations performed up to the examination may be indicated.

[0095] The scheduled imaging time 540 indicates the scheduled imaging time set based on injection information such as an injection protocol along a time axis showing the injection timing and imaging execution time. In this embodiment, the scheduled imaging time 540 includes a start time 541 of the scheduled imaging time, an end time 542 of the scheduled imaging time, and a scheduled peak time 543 at which the CT value (pixel value) at the imaging site reaches a peak. As described above, the scheduled imaging time may be calculated using any known contrast agent simulator, or may be calculated using the results of a test injection or the like performed based on an injection protocol, a bolus tracking method, or the like.

[0096] As described above, in the inspection system 10 according to this embodiment, the injection information further includes the injection timing. Furthermore, the generating unit 313 generates, as the inspection result screen 500, a screen showing the injection timing, the planned imaging time, and the imaging execution time along the same time axis.

[0097] With such a configuration, the examination system 10 according to this embodiment can efficiently present information on the success or failure of angiography and on the performed imaging. In particular, on the examination result screen 500 according to this embodiment, the injection timing, the planned imaging time, and the imaging execution time are displayed on the same time axis, making it easy to visually grasp whether the imaging was performed appropriately in response to the injection of the medicinal liquid.

[0098] Also, the examination result screen 500 according to this embodiment can display information on the injection of the drug solution and imaging, the captured image, and the result of the judgment on the success or failure of the imaging all at once. Therefore, even when the examination system according to this embodiment is used, it is possible to efficiently judge the success or failure of the imaging and to specify the cause of failure. Note that the various configuration changes described in the first embodiment can also be applied to this embodiment as appropriate.

[0099] In this embodiment, an example in which imaging is performed within the injection time of saline has been shown, but the timing at which imaging should be performed varies depending on the site or range to be imaged, the injection protocol, the condition of the patient, and the like. For this reason, there may be a gap between the injection timing of the contrast agent or saline and the scheduled imaging time. In this case, the generating unit 313 may omit the time from after the injection timing of the contrast agent or saline to before the scheduled imaging time, and the like. In addition, the length of the time axis may be appropriately changed depending on the injection timing of the contrast agent or saline, the scheduled imaging time, and the like.

[0100] (Variation 2) In the above embodiment and modification, output unit 314 outputs the generated screen to any device such as injection device 100 or imaging device 200. In contrast, in modification 2 of the present invention, the output unit outputs to a storage device a screen from which the personal information of the subject has been deleted from the generated screen.

[0101] The configuration of the inspection system according to this modification is similar to that of the inspection system according to Examples 1 and 2 and Modification 1, and therefore the same reference numerals are used and the description is omitted. Also, the series of processes according to this embodiment is similar to the series of processes according to Examples 1 and 2 and Modification 1, and therefore the description is omitted. The following describes the inspection system according to this modification, focusing on the differences from the inspection system according to Example 1.

[0102] As described above, in a medical examination system including an imaging device, information on examinations in which contrast failed and examination results are useful for verifying injection and imaging protocols from the viewpoint of improving the success rate of contrast in future examinations. However, from the viewpoint of protecting personal information, it is not preferable for personal information to be included in the stored data. Therefore, in this modification, a screen in which the personal information of the subject is deleted from the examination result screen 400A, 400B, 500 is output to a storage device and stored. Here, the storage device may be, for example, a storage device included in the storage unit 340 of the information processing device 300, or a storage device included in any server such as the injection device 100, the imaging device 200, the RIS 11, the PACS 12, the HIS 13, or a cloud server.

[0103] According to this modification, information useful for verifying injection and imaging protocols can be efficiently accumulated while taking into consideration the protection of personal information. If the examination result screens 400A, 400B, and 500 contain identification information of the examiner, the image from which the information has been deleted may be output to the storage device. The various configuration changes described in the first embodiment can also be applied to this modification as appropriate.

[0104] The various functions described in the above embodiment and modified examples may be realized by a program or a circuit for a software module executed by a computer including a processor such as a CPU or an MPU and an arbitrary memory. The program may be stored in the storage unit 340, or may be provided to the information processing device 300 or the like via an arbitrary network.

[0105] Although the present invention has been described above with reference to the embodiments, the present invention is not limited to the above embodiments and modifications. Inventions modified within the scope of the present invention and inventions equivalent to the present invention are also included in the present invention. In addition, the above embodiments and modifications can be appropriately combined within the scope of the present invention. [Explanation of symbols]
