[0007] Hereinafter, embodiments of a medical image diagnostic apparatus, a medical image processing apparatus, and a medical image processing system will be described in detail with reference to the drawings. Note that the medical image diagnostic apparatus, the medical image processing apparatus, and the medical image processing system according to the present application are not limited to the embodiments shown below. In addition, in the following description, similar components are given common reference numerals, and duplicated descriptions will be omitted.

[0008] (First embodiment) Fig. 1 is a diagram showing an example of the configuration of a medical image processing system 100 according to the first embodiment. As shown in Fig. 1, the medical image processing system 100 includes a HIS (Hospital Information System) 1, a RIS (Radiology Information System) 2, a medical image diagnostic device 3, and a medical image processing device 4, which are connected to each other so as to be able to communicate with each other via a network 200. For example, the medical image processing system 100 is constructed by an in-hospital LAN (Local Area Network) installed in a hospital. Note that various other devices and systems may be connected to the network 200 shown in Fig. 1.

[0009] The HIS1 includes an HIS server and a terminal device, and is connected to other devices and systems connected to the network 200, and transmits and receives various information to and from each other. For example, the HIS1 transmits patient information and order information to each device and system, and receives reports on the results of implementation performed by each device and system. The HIS1 also transmits implementation results and reference information in response to requests from each device and system.

[0010] The RIS 2 includes a RIS server and a terminal device, and is connected to other devices and systems connected to the network 200, and transmits and receives various information to and from them. For example, the RIS 2 transmits and receives various information related to testing operations between each device and each system. The RIS 2 also transmits test results and the like in response to requests from each device and each system.

[0011] The medical image diagnostic device 3 is a device for performing various examinations on a subject. For example, the medical image diagnostic device 3 is an X-ray diagnostic device, an X-ray CT (Computed Tomography) device, an MRI (Magnetic Resonance Imaging) device, an ultrasonic examination device, an endoscopic examination device, a SPECT (Single Photon Emission Computed Tomography) device, a PET (Positron Emission computed Tomography) device, etc. The medical image diagnostic device 3 collects image data (medical images) from a subject, transmits the collected image data to the medical image processing device 4, and receives an analysis result of the image data from the medical image processing device 4.

[0012] The medical image processing device 4 receives image data from the medical image diagnostic device 3, analyzes the image data, and transmits the analysis result to the medical image diagnostic device 3. For example, the medical image processing device 4 is realized by a computer device such as a server, a workstation, or a personal computer.

[0013] Hereinafter, a detailed configuration of the medical image diagnostic apparatus 3 and the medical image processing apparatus 4 according to this embodiment will be described. Note that in this embodiment, an X-ray CT apparatus 3a will be taken as an example of the medical image diagnostic apparatus 3.

[0014] Fig. 2 is a diagram showing an example of the configuration of the X-ray CT apparatus 3a according to the first embodiment. As shown in Fig. 2, the X-ray CT apparatus 3a according to the first embodiment has a gantry device 10, a bed device 20, and a console device 30, and is connected to a camera 51 and a projector 52.

[0015] The camera 51 captures the inside of the examination room in which the X-ray CT device 3a is installed. Specifically, the camera 51 collects images of the periphery of the X-ray CT device 3a and transmits the collected images to the X-ray CT device 3a. The light projector 52 irradiates light into the examination room under the control of the X-ray CT device 3a. Specifically, the light projector 52 irradiates light to positions in the examination room where the subject and the operator come into contact.

[0016] The gantry device 10 has an X-ray tube 11, an X-ray detector 12, a rotating frame 13, an X-ray high voltage device 14, a control device 15, a wedge 16, a collimator 17, and a DAS (Data Acquisition System) 18.

[0017] The X-ray tube 11 has a cathode (filament) that generates thermoelectrons and an anode (target) that generates X-rays upon collision with the thermoelectrons. By applying a high voltage from the X-ray high voltage device 14, thermoelectrons are irradiated from the cathode to the anode, thereby generating X-rays to be irradiated to the subject P.

[0018] The X-ray detector 12 has a plurality of detection elements for detecting X-rays. Each detection element in the X-ray detector 12 detects X-rays irradiated from the X-ray tube 11 and passing through the subject P, and outputs a signal corresponding to the detected X-ray amount to the DAS 18. The X-ray detector 12 has, for example, a plurality of detection element rows in which a plurality of detection elements are arranged in a channel direction (channel direction) along one arc centered on the focus of the X-ray tube 11. The X-ray detector 12 has, for example, a structure in which a plurality of detection element rows in which a plurality of detection elements are arranged in the channel direction are arranged in a row direction (slice direction, row direction). The X-ray detector 12 may be of an indirect conversion type or a direct conversion type.

[0019] The rotating frame 13 is an annular frame that supports the X-ray tube 11 and the X-ray detector 12 so as to face each other, and rotates the X-ray tube 11 and the X-ray detector 12 using a control device 15. The X-ray high voltage device 14 has electric circuits such as a transformer and a rectifier, and includes a high voltage generator that generates a high voltage to be applied to the X-ray tube 11, and an X-ray control device that controls the output voltage according to the X-rays generated by the X-ray tube 11.

[0020] The control device 15 includes a processing circuit having a CPU (Central Processing Unit) and the like, and a driving mechanism having a motor, an actuator, etc. The control device 15 receives an input signal from an input interface 42 and controls the operation of the gantry device 10 and the bed device 20.

[0021] The wedge 16 is a filter for adjusting the amount of X-rays irradiated from the X-ray tube 11. For example, the wedge 16 is a wedge filter or a bow-tie filter, which is a filter made of aluminum or the like processed to have a predetermined target angle and a predetermined thickness. The collimator 17 is a lead plate or the like for narrowing down the irradiation range of the X-rays that have passed through the wedge 16, and a slit is formed by combining multiple lead plates or the like.

[0022] The DAS 18 collects X-ray signals detected by each detection element of the X-ray detector 12. For example, the DAS 18 has an amplifier that performs an amplification process on the electrical signal output from each detection element, and an A / D converter that converts the electrical signal into a digital signal, and generates detection data. The DAS 18 is realized by, for example, a processor.

[0023] The bed device 20 is a device on which the subject P to be imaged is placed and moved, and includes a base 21, a bed driving device 22, a top plate 23, and a support frame 24. The base 21 is a housing that supports the support frame 24 so that it can move in the vertical direction. The bed driving device 22 is a drive mechanism that moves the top plate 23, on which the subject P is placed, in the longitudinal direction of the top plate 23, and includes a motor, an actuator, etc. The top plate 23, which is provided on the upper surface of the support frame 24, is a plate on which the subject P is placed.

[0024] The console device 30 includes a memory 31, a display 32, an input interface 33, and a processing circuit .

[0025] The memory 31 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory), a flash memory, a hard disk, an optical disk, etc. The memory 31 stores, for example, projection data and CT image data. Also, for example, the memory 31 stores a program for enabling a circuit included in the X-ray CT device 3a to realize its function.

[0026] The display 32 displays various information. For example, the display 32 displays various images generated by the processing circuit 34, and displays a GUI (Graphical User Interface) for receiving various operations from an operator. The display 32 also displays the analysis results by the medical image processing device 4. The analysis results by the medical image processing device 4 will be described in detail later. For example, the display 32 is realized by a liquid crystal display, a CRT (Cathode Ray Tube) display, an organic EL display, a plasma display, a touch panel, or the like. Here, the display 32 includes a display included in the console device 30 as well as a display provided on the gantry device 10. The display 32 is an example of a display unit.

[0027] The input interface 33 accepts various input operations from an operator, converts the accepted input operations into electrical signals, and outputs the electrical signals to the processing circuitry 34. In addition, for example, the input interface 33 accepts input operations from the operator, such as scan conditions, reconstruction conditions when reconstructing CT image data, and image processing conditions when generating a post-processed image from the CT image data.

[0028] For example, the input interface 33 is realized by a mouse, a keyboard, a trackball, a switch, a button, a joystick, a touchpad that performs an input operation by touching an operation surface, a touch screen in which a display screen and a touchpad are integrated, a non-contact input circuit using an optical sensor, a voice input circuit, or the like. The input interface 33 may be provided in the pedestal device 10. The input interface 33 may also be configured by a tablet terminal or the like that can wirelessly communicate with the console device 30 main body. The input interface 33 is not limited to only those that have physical operation parts such as a mouse and a keyboard. For example, an example of the input interface 33 includes an electrical signal processing circuit that receives an electrical signal corresponding to an input operation from an external input device provided separately from the console device 30 and outputs the electrical signal to the processing circuit 34.

[0029] The processing circuitry 34 controls the operation of the entire X-ray CT device 3a. For example, the processing circuitry 34 executes an acquisition function 341, a transmission / reception function 342, and a control function 343. Here, for example, the processing functions executed by the acquisition function 341, the transmission / reception function 342, and the control function 343, which are components of the processing circuitry 34 shown in FIG. 2, are recorded in the memory 31 in the form of a program executable by a computer. The processing circuitry 34 is, for example, a processor, and realizes a function corresponding to each program read out by reading out each program from the memory 31 and executing it. In other words, the processing circuitry 34 in a state in which each program has been read out has each function shown in the processing circuitry 34 in FIG. 2.

[0030] 2 shows a case where the processing functions of the collection function 341, the transmission / reception function 342, and the control function 343 are realized by a single processing circuit 34, but the embodiment is not limited to this. For example, the processing circuit 34 may be configured by combining multiple independent processors, and each processor may execute each program to realize each processing function. Furthermore, each processing function of the processing circuit 34 may be realized by being appropriately distributed or integrated into a single or multiple processing circuits.

[0031] The acquisition function 341 controls various processes related to the acquisition of CT image data based on an input operation received from an operator via the input interface 33. Specifically, the acquisition function 341 controls the CT scan performed by the gantry device 10. For example, the acquisition function 341 controls the operations of the X-ray high voltage device 14, the X-ray detector 12, the control device 15, the DAS 18, and the bed driving device 22, thereby controlling the CT scan in the gantry device 10. More specifically, the acquisition function 341 controls the acquisition process of projection data and the image generation process based on the projection data in a positioning scan for acquiring a positioning image (scanogram) and in imaging (main scan) for acquiring an image used for diagnosis.

[0032] For example, the acquisition function 341 performs pre-processing such as logarithmic conversion processing, offset correction processing, inter-channel sensitivity correction processing, and beam hardening correction on the detection data output from the DAS 18 to generate projection data. The acquisition function 341 also performs reconstruction processing using a filtered back projection method, an iterative reconstruction method, or the like on the projection data to generate CT image data. The acquisition function 341 also converts the CT image data into a CT image such as a tomographic image of an arbitrary cross section or a three-dimensional image by rendering processing, using a known method. The acquisition function 341 is an example of an acquisition unit.

[0033] The transmission / reception function 342 transmits and receives various information between each device and each system connected to the network 200. Specifically, the transmission / reception function 342 transmits the processing results by the X-ray CT device 3a to each device and each system connected to the network 200. The transmission / reception function 342 also receives various information from each device and each system connected to the network 200. For example, the transmission / reception function 342 transmits CT image data to the medical image processing device 4. The transmission / reception function 342 also receives the analysis results from the medical image processing device 4. The transmission / reception function 342 is an example of a transmitting unit and a receiving unit.

[0034] The control function 343 controls so that various image data stored in the memory 31, information related to the analysis results received by the transmission / reception function 342, and the like are displayed on the display 32. The control function 343 also acquires an image from the camera 51, and controls the irradiation of light by the projector 52 based on the acquired image.

[0035] 3 is a diagram showing an example of the configuration of a medical image processing device 4 according to the first embodiment. The medical image processing device 4 performs various information processing related to a subject. Specifically, the medical image processing device 4 acquires image data from a medical image diagnostic device 3 via a network, and performs various information processing using the image data. For example, the medical image processing device 4 includes a communication interface 41, an input interface 42, a display 43, a memory 44, and a processing circuit 45.

[0036] The communication interface 41 controls the transmission and communication of various data transmitted and received between the medical image processing device 4 and other devices connected via a network. For example, the communication interface 41 is realized by a network card, a network adapter, a NIC (Network Interface Controller), etc.

[0037] The input interface 42 accepts various instructions and various information input operations from the operator of the medical image processing device 4. Specifically, the input interface 42 is connected to the processing circuit 45, converts the input operation received from the operator into an electrical signal, and outputs the electrical signal to the processing circuit 45. For example, the input interface 42 is realized by a trackball, a switch button, a mouse, a keyboard, a touch pad that performs an input operation by touching the operation surface, a touch screen in which a display screen and a touch pad are integrated, a non-contact input interface using an optical sensor, and a voice input interface. In this specification, the input interface 42 is not limited to only those that have physical operation parts such as a mouse and a keyboard. For example, an electrical signal processing circuit that receives an electrical signal corresponding to an input operation from an external input device provided separately from the device and outputs the electrical signal to a control circuit is also included as an example of the input interface 42.

[0038] The display 43 displays various information and data. Specifically, the display 43 is connected to the processing circuit 45, and displays various information and data output from the processing circuit 45. For example, the display 43 is realized by a liquid crystal display, a CRT (Cathode Ray Tube) display, an organic EL display, a plasma display, a touch panel, or the like.

[0039] The memory 44 is realized by, for example, a semiconductor memory element such as a random access memory (RAM) or a flash memory, a hard disk, an optical disk, etc. The memory 44 stores, for example, image data received from the medical image diagnostic apparatus 3. In addition, for example, the memory 44 stores a program for enabling a circuit included in the medical image processing apparatus 4 to realize its function.

[0040] The processing circuitry 45 controls the entire medical image processing device 4. For example, the processing circuitry 45 executes a control function 451, a transmission / reception function 452, and an analysis function 453. Here, for example, the processing functions executed by the control function 451, the transmission / reception function 452, and the analysis function 453, which are components of the processing circuitry 45 shown in FIG. 3, are recorded in the memory 44 in the form of a program executable by a computer. The processing circuitry 45 is, for example, a processor, and realizes a function corresponding to each program read out by reading out each program from the memory 44 and executing it. In other words, the processing circuitry 45 in a state in which each program has been read out has each function shown in the processing circuitry 45 in FIG. 3.

[0041] 3 shows a case where the control function 451, the transmission / reception function 452, and the analysis function 453 are realized by a single processing circuit 45, but the embodiment is not limited to this. For example, the processing circuit 45 may be configured by combining multiple independent processors, and each processor may execute a program to realize each processing function. Furthermore, each processing function of the processing circuit 45 may be realized by being appropriately distributed or integrated in a single or multiple processing circuits.

[0042] The control function 451 reads data from the memory 44 and controls the display 43 to display the data. The transmission / reception function 452 transmits and receives various information between each device and each system connected to the network 200 via the communication interface 41. For example, the transmission / reception function 452 receives image data from a medical image diagnostic device 3 (e.g., the X-ray CT device 3a). The transmission / reception function 452 also transmits the analysis results by the analysis function 453 to the medical image diagnostic device 3 (e.g., the X-ray CT device 3a). The transmission / reception function 452 is an example of a transmitting unit and a receiving unit.

[0043] The analysis function 453 analyzes the presence or absence of a disease in the subject from whom the image data was collected, based on image data received from the medical image diagnostic device 3 (for example, the X-ray CT device 3a). For example, the analysis function 453 executes an analysis using an analysis application such as CADx (Computer-Aided Diagnosis). As one example, the analysis function 453 quantitatively analyzes the image data and obtains an analysis result related to a differential diagnosis of a disease (infectious disease and killer disease) (for example, a probability of the presence of a certain image finding is expressed numerically). For example, the analysis function 453 executes an analysis application for each part and each type of image data to obtain an analysis result.

[0044] The above describes the configuration of the medical image processing system 100 according to this embodiment. With this configuration, the medical image diagnostic device 3, the medical image processing device 4, and the medical image processing system 100 according to this embodiment make it possible to appropriately handle the medical images after they are collected.

[0045] In clinical practice, if a disease is predicted to some extent from the clinical symptoms of a subject, medical staff can take measures in advance and conduct the examination. However, there are cases where a subject has a disease such as an infectious disease or a killer disease without symptoms. In this case, the medical image diagnostic device does not have the function to determine whether or not the subject may have an infectious disease or a killer disease after imaging, so the response depends on the operator performing the examination. In other words, if the operator is familiar with interpreting infectious diseases and killer diseases, he or she can immediately notice the important findings, but if not, the operator may not notice the subject with the above-mentioned disease, which may lead to infection of medical staff, spread of infection within the hospital, and sudden change in condition due to the killer disease being left untreated.

[0046] Therefore, the medical image diagnostic apparatus 3 (X-ray CT apparatus 3a) of this embodiment transmits collected image data to the medical image processing apparatus 4, receives the analysis results by the analysis application, and displays warning information based on the analysis results, thereby enabling appropriate response after collecting medical images.

[0047] In the following, in the first embodiment, a process for a case where a subject is infected with an infectious disease will be described. Note that the process in this embodiment does not apply to a test of a subject who has already been confirmed to be infected with an infectious disease before the test.

[0048] FIG. 4 is a sequence diagram showing a flow of processing by the medical image processing system 100 according to the first embodiment. Step S101 in FIG. 4 is realized by the processing circuitry 34 reading a program corresponding to the collection function 341 from the memory 31 and executing it. Step S102 is realized by the processing circuitry 34 reading a program corresponding to the transmission / reception function 342 from the memory 31 and executing it. Step S106 is realized by the processing circuitry 34 reading a program corresponding to the control function 343 from the memory 31 and executing it. Step S103 is realized by the processing circuitry 45 reading a program corresponding to the analysis function 453 from the memory 44 and executing it. Steps S104 and S105 are realized by the processing circuitry 45 reading a program corresponding to the transmission / reception function 452 from the memory 44 and executing it.

[0049] Here, in the transmission and reception of data in the medical image processing system 100, each device constantly monitors the reception of data and executes processing in response to the reception of the data. For example, the medical image processing system 100 transmits and receives the data shown in Fig. 5. Fig. 5 is a diagram for explaining an example of data transmitted and received by the medical image processing system 100 according to the first embodiment.

[0050] For example, data transmitted and received by the medical image processing system 100 has a "Message ID" indicated by a "data format", a "source IP" conforming to "IPv4" or "IPv6", a "source device ID / source device name" indicated by a "numeric value / character string", a "destination IP" conforming to "IPv4" or "IPv6", and a "destination device ID / destination device name" indicated by a "numeric value / character string", as shown in Fig. 5. Also, data transmitted and received by the medical image processing system 100 has a flag "Flag_urgency" of "URGENT / WARNING / INFO" as shown in Fig. 5. That is, data transmitted and received in the process shown in Fig. 4 is preferentially transmitted compared to other data.

[0051] In addition, the data sent and received by the medical image processing system 100 has data represented by a "character string" as "message content" as shown in Figure 5, and has a "related examination ID" and a "related subject ID" represented by a "character string".

[0052] For example, in the medical image processing system 100 according to the first embodiment, first, the processing circuitry 34 in the X-ray CT device 3a acquires CT images (step S101) and transmits the acquired CT images to the medical image processing device 4 (step S102), as shown in Fig. 4. The CT images transmitted from the X-ray CT device 3a may be CT image data obtained by reconstruction processing, or may be CT images obtained by performing image processing on the CT image data.

[0053] When the CT image is received from the X-ray CT device 3a, the processing circuitry 45 of the medical image processing device 4 analyzes the CT image (step S103) and determines whether there is a suspicion of an infectious disease (step S104). Specifically, the processing circuitry 45 automatically starts an analysis application in response to receiving the CT image, and executes an analysis using the analysis application for distinguishing the infectious disease. More specifically, the processing circuitry 45 selects all analysis applications that can be used for the received data based on the data format and data contents of the received data, and executes an analysis using the selected analysis application.

[0054] For example, the processing circuitry 45 selects all applicable analysis applications according to the imaged part and the type of image, and executes analysis using the selected analysis applications. As an example, the processing circuitry 45 selects all applicable analysis applications for a plain CT image of the chest, and executes analysis.

[0055] Then, the processing circuitry 45 determines whether or not there is a suspicion of an infectious disease as a result of the analysis by the analysis application. That is, the processing circuitry 45 determines whether or not there is a suspicion of an infectious disease in all the results of the executed analysis applications.

[0056] Here, if there is no suspicion of an infectious disease (step S104, negative), the processing circuitry 45 transmits the analysis result to the RIS 2. On the other hand, if there is a suspicion of an infectious disease (step S104, positive), the processing circuitry 45 transmits a result indicating a suspicion of an infectious disease to the X-ray CT device 3a and the RIS 2 (step S105). The RIS 2 manages the analysis result received from the medical image processing device 4 in association with the subject information.

[0057] In the X-ray CT device 3a, when the analysis result is received from the medical image processing device 4, the processing circuitry 34 causes the display 32 to display warning information based on the analysis result (step S106). Specifically, the display 32 displays warning information indicating that the subject from which the CT image was collected may have a disease. In addition, the processing circuitry 34 identifies the position in the examination room where the subject and / or the operator has come into contact based on the image captured by the camera 51, and irradiates the identified position with light from the projector 52.

[0058] 6 is a schematic diagram showing an example of processing in the medical image processing system 100 according to the first embodiment. For example, in the medical image processing system 100, the X-ray CT device 3a captures images to collect CT images, and transmits the CT images to an analysis application in the medical image processing device 4. At the same time, the X-ray CT device 3a transmits the collected CT images to an interpretation terminal.

[0059] The analysis application in the medical image processing device 4 detects the possibility of infection. Then, the medical image processing device 4 transmits the detected information of the suspected infection to the X-ray CT device 3a. At the same time, the medical image processing device 4 transmits a report on the analysis result to the image interpretation terminal.

[0060] When receiving information on a suspected infection from the medical image processing device 4, the X-ray CT device 3a displays an alert on the display 32. For example, the processing circuitry 34 of the X-ray CT device 3a causes the display 32 to display an alert indicating information on the possibility of infection, the name of the subject, and the date and time, as shown in Fig. 6.

[0061] Furthermore, the processing circuitry 34 causes the display 32 to display a risk map as information showing the position in the examination room where the subject touched. For example, the processing circuitry 34 controls the display 32 to highlight the location where the subject touched in an external view of the X-ray CT device 3a (for example, a view of a device model of the X-ray CT device 3a). Note that the processing circuitry 34 can also display information on the position where the operator touched, in addition to the information on the position where the subject touched, as a similar risk map.

[0062] Here, the processing circuitry 34 can change the display form of the warning information depending on the implementation status of the examination. Specifically, the processing circuitry 34 changes the display form of the warning information depending on whether or not a scan is in progress. For example, when the scan is completed, the processing circuitry 34 displays the warning information on the entire operation screen of the display 32, as shown in FIG. 6. On the other hand, when the scan is not completed, the processing circuitry 34 displays the warning information with priority given to the irradiation of X-rays. As an example, the processing circuitry 34 displays the warning information as a pop-up in the upper right corner of the operation screen during a scan.

[0063] Furthermore, the processing circuitry 34 controls the projector 52 to irradiate light onto a location touched by the subject in the examination room, thereby clearly indicating the contact position of the subject. For example, as shown in Fig. 6, the processing circuitry 34 causes the projector 52 to irradiate light onto a location touched by the subject's hand on the top board 23 of the X-ray CT device 3a installed in the examination room. Also, as shown in Fig. 6, the processing circuitry 34 causes the projector 52 to irradiate light onto a location touched by the subject's hand on the gantry device 10 of the X-ray CT device 3a. The processing circuitry 34 can also control the projector 52 to irradiate light onto a location touched by the operator's hand during the examination of the subject.

[0064] When the X-ray CT device 3a displays the warning information, the operator can confirm the information that the subject may have an infectious disease. As a result, if the subject is still in the examination room, the operator can take measures against the infectious disease and deal with the subject. In addition, the operator can take measures to keep the subject in the examination room as necessary.

[0065] In addition, after the subject leaves the examination room, the position illuminated by the light projector 52 can be properly cleaned.

[0066] As described above, according to the first embodiment, the collection function 341 collects CT images. The transmission / reception function 342 transmits the CT images to the medical image processing device 4 that analyzes diseases based on the medical images, and receives the analysis results from the medical image processing device 4. The display 32 displays warning information based on the analysis results. Therefore, the X-ray CT device 3a according to the first embodiment can present warning information based on the analysis results to an operator in the examination room, enabling appropriate action to be taken after the medical images are collected.

[0067] Furthermore, according to the first embodiment, the display 32 displays warning information indicating that the subject from whom the medical image was collected may have a disease (infectious disease). Therefore, the X-ray CT apparatus 3a according to the first embodiment can present warning information indicating that the subject may have a disease (infectious disease) to an operator in the examination room, enabling the operator to take appropriate measures against the subject having an infectious disease.

[0068] For example, even if the operator is not familiar with image interpretation, the operator can be aware of the possibility of an infectious disease, and the operator's own risk of infection can be reduced. Also, even if the operator is not familiar with image interpretation, the operator can be aware of the possibility of an infectious disease, and by controlling the behavior of the subject after the examination, unnecessary spread of infection can be prevented. Also, overlooking important findings of the subject can be reduced, and treatment can be intervened at an earlier stage. Also, overlooking important findings of the subject can be reduced, and the risk of litigation due to malpractice by medical staff can be reduced.

[0069] According to the first embodiment, the display 32 displays warning information indicating the area where the subject, whose medical image was collected, has come into contact. Therefore, the X-ray CT apparatus 3a according to the first embodiment can perform appropriate cleaning of the area possibly contaminated by pathogens, thereby making it possible to prevent the spread of infection.

[0070] Moreover, according to the first embodiment, the transmission / reception function 452 receives medical images collected by the X-ray CT device 3a. The analysis function 453 analyzes a disease based on the medical images. The transmission / reception function 452 transmits the analysis result to the X-ray CT device 3a. Therefore, the medical image processing device 4 according to the first embodiment can present warning information to an operator in an examination room indicating that the subject may be suffering from a disease (infectious disease), and enables appropriate measures to be taken for the subject having an infectious disease.

[0071] Second embodiment In the above-described first embodiment, a case where an analysis result indicating a suspected infection is transmitted to the X-ray CT apparatus 3a is described. In the second embodiment, a case where an analysis result indicating a suspected infection is transmitted to another medical image diagnostic apparatus 3 is described. Note that in the second embodiment, the processing by the transmission / reception function 452 is different from that in the first embodiment. This will be mainly described below.

[0072] When the analysis result indicates that the subject from which the medical image was collected is suspected of having an infectious disease, the transmission / reception function 452 according to the second embodiment transmits the analysis result to the medical image diagnostic apparatus 3 that examined the subject within a predetermined time. For example, the transmission / reception function 452 transmits the analysis result indicating a suspicion of an infectious disease to the medical image diagnostic apparatuses that examined the same subject within 24 hours.

[0073] Fig. 7 is a sequence diagram showing the flow of processing by the medical image processing system 100 according to the second embodiment. Here, Fig. 7 is obtained by adding steps S107 to S109 to the flow of processing of the first embodiment shown in Fig. 4. Steps S107 and S108 are realized by a processing circuit in the RIS 2 reading and executing a corresponding program. Also, step S109 is realized by a processing circuit in the medical image diagnostic apparatus 3 reading and executing a corresponding program.

[0074] For example, in the medical image processing system 100 according to the second embodiment, as shown in Fig. 7, first, the processing circuitry 34 in the X-ray CT device 3a collects a CT image (step S101) and transmits the collected CT image to the medical image processing device 4 (step S102). Upon receiving the CT image from the X-ray CT device 3a, the processing circuitry 45 of the medical image processing device 4 analyzes the CT image (step S103) and determines whether or not there is a suspicion of an infectious disease (step S104).

[0075] Here, if there is no suspicion of an infectious disease (step S104, negative), the processing circuitry 45 transmits the analysis result to the RIS 2. On the other hand, if there is a suspicion of an infectious disease (step S104, positive), the processing circuitry 45 transmits a result indicating a suspicion of an infectious disease to the X-ray CT device 3a (step S105). When the X-ray CT device 3a receives the analysis result from the medical image processing device 4, the processing circuitry 34 causes the display 32 to display warning information based on the analysis result (step S106).

[0076] Furthermore, if there is a suspicion of an infectious disease (step S104, Yes), the processing circuitry 45 transmits the analysis result indicating a suspicion of an infectious disease to the RIS 2. Here, by transmitting the analysis result to the RIS 2, the processing circuitry 45 causes the RIS 2 to transmit the transmitted analysis result to another modality.

[0077] When the RIS 2 receives the analysis result from the medical image processing device 4, it extracts the modalities that examined the subject within 24 hours (step S107). For example, the RIS 2 extracts the modalities that examined the subject within 24 hours based on the subject ID of the received data. Then, the RIS 2 transmits a result indicating a suspected infection to the extracted modalities (step S108).

[0078] When the medical image diagnostic device 3 receives the analysis result from the RIS, the processing circuit of the other medical image diagnostic device 3 other than the X-ray CT device 3a displays warning information based on the analysis result on the display of the own device (step S109). Here, the processing circuit of the other medical image diagnostic device 3 displays warning information indicating that the subject may have an infectious disease, identifies the position in the examination room where the subject and / or the operator has come into contact, and displays information on the identified position.

[0079] Fig. 8 is a schematic diagram showing an example of processing in the medical image processing system 100 according to the second embodiment. For example, as shown in Fig. 8, in the medical image processing system 100 according to the second embodiment, when an analysis application in the medical image processing device 4 detects the possibility of infection, the medical image processing device 4 transmits information on the detected suspected infection to other modalities (medical image diagnostic devices 3 other than the X-ray CT device 3a) that the subject underwent treatment on that day.

[0080] When receiving information of a suspected infection from the medical image processing device 4, the medical image diagnostic device 3 other than the X-ray CT device 3a displays an alert on the display 32. For example, the medical image diagnostic device 3 other than the X-ray CT device 3a displays an alert indicating information indicating the possibility of infection, the name of the subject, the date and time, and a risk map on the display of the own device, as shown in Fig. 6. Furthermore, the medical image diagnostic device 3 other than the X-ray CT device 3a can also control the device to irradiate light from a projector onto a location touched by the subject in the examination room, to clearly indicate the contact position of the subject.

[0081] When warning information is displayed by a medical image diagnostic device 3 other than the X-ray CT device 3a, medical staff in the examination room in which the medical image diagnostic device 3 is installed can confirm the information that the subject may have an infectious disease, and can take appropriate measures such as cleaning.

[0082] Here, the medical image processing system 100 can also identify other subjects suspected of having come into contact with a subject determined to be suspected of having an infectious disease. In the medical image processing system 100, the implementation status of an examination is notified to the RIS 2 from each modality by a Modality Performed Procedure Step (MPPS). For example, the medical image diagnostic device 3 notifies the RIS 2 of the implementation status of the examination, such as completed, discontinued, or in progress.

[0083] Therefore, the processing circuit 45 of the medical image processing device 4 transmits data including information on suspected infectious diseases to the RIS 2, and identifies the test ID and subject ID included in the data and the subjects examined after that, thereby identifying other subjects suspected of having come into contact with the subject determined to be suspected of having an infectious disease.

[0084] As described above, according to the second embodiment, when the analysis result indicates that the subject from which the medical image was collected is suspected of having an infectious disease, the transmission / reception function 452 transmits the analysis result to the medical image diagnostic apparatus 3 that examined the subject within a predetermined time. Therefore, the medical image processing apparatus 4 according to the second embodiment can cause all medical image diagnostic apparatuses 3 that have examined the subject to present warning information, making it possible to further prevent the spread of infectious diseases.

[0085] (Third embodiment) In the first and second embodiments, the case of analyzing the presence or absence of an infectious disease is described. In the third embodiment, the case of analyzing the presence or absence of a killer disease is described. Note that the third embodiment is different from the first and second embodiments in the processing contents by the control function 343 and the processing contents by the analysis function 453. The following description will focus on these.

[0086] In the medical image processing device 4, the analysis function 453 according to the third embodiment executes an analysis application for distinguishing killer disease and obtains an analysis result. Specifically, the analysis function 453 executes the analysis application on the CT image received from the X-ray CT device 3a to analyze whether or not there is a suspicion of killer disease. The transmission / reception function 452 transmits the analysis result by the analysis function 453 to the X-ray CT device 3a.

[0087] In the X-ray CT apparatus 3a, the control function 343 according to the third embodiment displays warning information based on the analysis result on the display 32. Specifically, the display 32 displays warning information indicating that the subject from whom the CT image was acquired may have a disease (killer disease).

[0088] 9 is a schematic diagram showing an example of processing in the medical image processing system according to the third embodiment. For example, in the medical image processing system 100 according to the third embodiment, the X-ray CT device 3a captures images to collect CT images, and transmits the CT images to an analysis application in the medical image processing device 4. At the same time, the X-ray CT device 3a transmits the collected CT images to an interpretation terminal.

[0089] The analysis application in the medical image processing device 4 detects the possibility of being affected by killer disease. Then, the medical image processing device 4 transmits the detected information of the suspicion of killer disease to the X-ray CT device 3a. At the same time, the medical image processing device 4 transmits a report on the analysis result to the image interpretation terminal.

[0090] When receiving information on a suspicion of killer disease from the medical image processing device 4, the X-ray CT device 3a displays an alert on the display 32. For example, the processing circuitry 34 of the X-ray CT device 3a causes the display 32 to display information indicating the possibility of killer disease and an alert indicating how to respond to the subject, as shown in Fig. 9. As one example, the processing circuitry 34 causes the display 32 to display warning information such as "Keep the patient lying down" or "Do not move the patient until the attending physician gives permission."

[0091] When the X-ray CT device 3a displays the warning information, the operator can confirm the information that the subject may have a killer disease. As a result, the operator can take measures to prevent the subject from being moved unnecessarily. The operator can also prepare a transport device such as a stretcher or take actions to avoid stimulation.

[0092] As described above, according to the third embodiment, the display 32 displays warning information indicating that the subject from which the medical image was collected may have a disease (killer disease). Therefore, the X-ray CT apparatus 3a according to the third embodiment can present warning information indicating that the subject may have a disease (killer disease) to an operator in the examination room, enabling the operator to take appropriate measures against the subject having a killer disease.

[0093] For example, even if the operator is not familiar with image interpretation, he or she can be aware of the possibility of a killer disease and prevent the patient's condition from worsening by controlling the patient's subsequent behavior. In addition, it is possible to reduce the oversight of important findings in the subject, allowing for earlier intervention in treatment. It is also possible to reduce the oversight of important findings in the subject, reducing the risk of lawsuits due to medical staff errors.

[0094] (Fourth embodiment) In the third embodiment, a process before a subject who may have killer disease leaves an examination room is described. In the fourth embodiment, a case where a subject who may have killer disease leaves an examination room is described. In addition, in the fourth embodiment, the process contents by the transmission / reception function 342 and the control function 343 are different from those in the third embodiment. This will be described below.

[0095] When the control function 343 according to the fourth embodiment receives an analysis result indicating that the subject may have a killer disease, it determines whether the subject has left the examination room. For example, when the analysis result indicates that the subject from whom the medical image was collected is suspected of having a killer disease, the display 32 displays information for confirming whether the subject has left the examination room. Then, when the subject has left the examination room, the transmission / reception function 342 transmits information to various devices on the network to prevent the subject from returning home.

[0096] FIG. 10 is a sequence diagram showing a flow of processing by the medical image processing system 100 according to the fourth embodiment. Step S201 in FIG. 10 is realized by the processing circuitry 34 reading out from the memory 31 a program corresponding to the collection function 341 and executing it. Steps S202, S209, and S210 are realized by the processing circuitry 34 reading out from the memory 31 a program corresponding to the transmission / reception function 342 and executing it. Steps S206 to S208 are realized by the processing circuitry 34 reading out from the memory 31 a program corresponding to the control function 343 and executing it. Step S203 is realized by the processing circuitry 45 reading out from the memory 44 a program corresponding to the analysis function 453 and executing it. Steps S204 and S205 are realized by the processing circuitry 45 reading out from the memory 44 a program corresponding to the transmission / reception function 452 and executing it. Step S211 is realized by the processing circuitry of the HIS server included in the HIS1 reading out from the memory a corresponding program and executing it.

[0097] Here, in the data transmission and reception in the medical image processing system 100 according to the fourth embodiment, each device constantly monitors the reception of data and executes processing in response to the reception of data. For example, the medical image processing system 100 transmits and receives the data shown in FIG.

[0098] For example, in the medical image processing system 100 according to the fourth embodiment, first, the processing circuitry 34 in the X-ray CT device 3a acquires CT images (step S201) and transmits the acquired CT images to the medical image processing device 4 (step S202), as shown in Fig. 10. Note that the CT images transmitted from the X-ray CT device 3a may be CT image data obtained by reconstruction processing, or may be CT images obtained by performing image processing on the CT image data.

[0099] When the CT image is received from the X-ray CT device 3a, the processing circuitry 45 of the medical image processing device 4 analyzes the CT image (step S203) and judges whether or not there is a suspicion of a killer disease (step S204). For example, the processing circuitry 45 selects all applicable analysis applications according to the imaged part and the type of image, and executes analysis using the selected analysis application.

[0100] Then, the processing circuitry 45 determines whether or not there is a suspicion of killer disease as a result of the analysis by the analysis application. That is, the processing circuitry 45 determines whether or not there is a suspicion of killer disease in all the results of the executed analysis applications.

[0101] Here, if there is no suspicion of killer disease (step S204, negative), the processing circuitry 45 transmits the analysis result to the RIS 2. On the other hand, if there is a suspicion of killer disease (step S204, positive), the processing circuitry 45 transmits a result indicating that there is a suspicion of killer disease to the X-ray CT device 3a and the RIS 2 (step S205). The RIS 2 manages the analysis result received from the medical image processing device 4 in association with the subject information.

[0102] In the X-ray CT device 3a, when the analysis result is received from the medical image processing device 4, the processing circuitry 34 displays warning information based on the analysis result on the display 32 (step S206). Specifically, the display 32 displays warning information indicating that the subject from whom the CT image was collected may have a disease (killer disease).

[0103] Then, the processing circuitry 34 judges whether the examination has been completed (step S207). If the examination has not been completed (step S207, negative), the processing circuitry 34 continues to display the warning information. On the other hand, if the examination has been completed (step S207, positive), the processing circuitry 34 displays a confirmation dialogue for confirming whether the subject has exited on the display 32 (step S208), and judges whether the subject has exited by accepting an input to the confirmation dialogue (step S209).

[0104] If the patient has not yet left the room (step S209, negative), the processing circuitry 34 continues to display the warning information. On the other hand, if the patient has already left the room (step S209, positive), the processing circuitry 34 transmits the result indicating a suspicion of killer disease to the HIS1 (step S210). When the HIS1 receives the result indicating a suspicion of killer disease from the X-ray CT device 3a, the HIS1 notifies each terminal included in the HIS1 of the result (step S211).

[0105] Fig. 11 is a schematic diagram showing an example of processing in the medical image processing system 100 according to the fourth embodiment. For example, in the medical image processing system 100 according to the fourth embodiment, when information indicating a suspected killer disease is received from the medical image processing device 4, the X-ray CT device 3a displays an alert on the display 32. Then, when the examination is completed, the processing circuitry 34 displays a confirmation dialogue for confirming whether or not the patient has left the examination on the display 32 as shown in Fig. 11, and determines whether or not the patient has left the examination by accepting an input to the confirmation dialogue.

[0106] Here, if the subject has already left the examination room, the processing circuit 34 transmits information on suspicion of killer disease to the HIS 1. Upon receiving the information on suspicion of killer disease, the HIS server in the HIS 1 transmits the information on suspicion of killer disease to, for example, a terminal device used at the time of payment, as shown in Fig. 11. The HIS server then displays warning information such as "Name," "Date and Time," and "Please keep this patient here as there are matters to be confirmed" on the display of the terminal device, thereby preventing the subject from going home.

[0107] In addition, the HIS server transmits a request to the terminal device of the attending physician of the subject to check the images and a notification to prompt the subject to decide whether or not the subject can go home, as shown in FIG.

[0108] As described above, according to the fourth embodiment, when the analysis result indicates that the subject from whom the medical image was collected is suspected of having a killer disease, the display 32 displays information for confirming whether the subject has left the room. Therefore, the X-ray CT device 3a according to the fourth embodiment makes it possible to confirm the location of the subject suspected of having a killer disease and take action.

[0109] Fifth embodiment In the first to fourth embodiments, a case where an analysis is performed on a CT image collected by a main scan of the X-ray CT device 3a is described. In the fifth embodiment, a case where an analysis is performed on a CT image collected by a positioning scan of the X-ray CT device 3a is described. In the fifth embodiment, the processing content by the analysis function 453 is different from that of the first to fourth embodiments. This will be mainly described below.

[0110] The analysis function 453 according to the fifth embodiment generates an analysis image from a three-dimensional positioning image collected by the X-ray CT device 3a, and analyzes a disease based on the analysis image. Specifically, the X-ray CT device 3a executes a three-dimensional positioning scan (3D scano) to determine the scan range of the main scan. Then, the transmission / reception function 342 in the X-ray CT device 3a transmits the CT image collected by the three-dimensional positioning scan to the medical image processing device 4.

[0111] The analysis function 453 generates an analysis image from a CT image collected by a three-dimensional positioning scan, and executes an analysis application on the generated analysis image. Here, the analysis function 453 generates the analysis image by, for example, a trained model based on machine learning. Fig. 12 is a diagram for explaining an example of processing by the analysis function 453 according to the fifth embodiment.

[0112] For example, as shown in the learning step in the upper part of Figure 12, the analysis function 453 generates a trained model by performing machine learning for multiple subjects using a 3D scan CT image (low quality image) as an input image and a CT image (high quality image) of the main scan of the same subject as a teacher image.

[0113] Then, the analysis function 453 generates an image for analysis (an image equivalent to high quality) by inputting the CT image collected by the 3D scano into the generated trained model, as shown in the usage steps in the lower part of Fig. 12. Furthermore, the analysis function 453 executes an analysis application on the generated image for analysis to obtain an analysis result for determining the presence or absence of a disease (an infectious disease and a killer disease).

[0114] As described above, according to the fifth embodiment, the analysis function 453 generates an analysis image from a 3D positioning image collected by the X-ray CT device 3a, and analyzes a disease based on the analysis image. Therefore, the medical image processing device 4 according to the fifth embodiment can detect an infectious disease or a killer disease at the time of performing 3D scanning, enabling a response at an earlier stage. Furthermore, when analysis can be performed using only the CT image of the 3D scanning, the medical image processing device 4 may not require a main scan in some cases, making it possible to prevent unnecessary exposure to radiation.

[0115] (Other embodiments) In the above-described embodiment, the case where the X-ray CT device 3a is used as the medical image diagnostic device 3 has been described. However, the embodiment is not limited to this, and other modalities such as an X-ray diagnostic device, an MRI device, and an ultrasonic diagnostic device may be used. In such a case, the processing circuit in each modality transmits medical images, receives analysis results, displays warning information, and the like.

[0116] In the above-described embodiment, the case where the transmission of the medical image from the medical image diagnostic apparatus 3 to the medical image processing apparatus 4 and the launch of the analysis application are automatically performed has been described. However, the embodiment is not limited to this, and the transmission of the medical image from the medical image diagnostic apparatus 3 to the medical image processing apparatus 4 and the launch of the analysis application may be manually performed.

[0117] In the above-described embodiment, the medical image processing device 4 transmits the analysis results (information on suspected infectious disease, information on suspected killer disease) to the medical image diagnostic device 3. However, the embodiment is not limited to this, and the analysis results may be transmitted to a control device that controls a display placed in the examination room.

[0118] In such a case, the transmission / reception function 452 in the medical image processing device 4 transmits the analysis results to a display device arranged in the room where the examination is performed by the medical image diagnostic device 3. For example, the examination room may be equipped with a monitoring monitor and a monitor displaying information on the HIS1 and RIS2. The transmission / reception function 452 transmits the analysis results to those monitors, thereby causing the warning information to be displayed on those monitors. Thus, the medical image processing device 4 makes it possible for the warning information to be widely confirmed by medical staff in the examination room.

[0119] In the above-described embodiment, the medical image processing device 4 executes the analysis by the analysis application. However, the embodiment is not limited to this, and the analysis may be executed in the medical image diagnostic device 3. In such a case, for example, a program corresponding to the analysis function 453 is stored in the memory 31 of the X-ray CT device 3a. Then, the processing circuitry 34 reads out the program corresponding to the analysis function 453 from the memory 31 and executes it, thereby executing the same process as the above-described analysis function 453.

[0120] In the above-mentioned embodiment, the collecting unit, the transmitting unit, the receiving unit, and the analyzing unit in this specification are respectively realized by the collecting function, the transmitting / receiving function, and the analyzing function of the processing circuit, but the embodiment is not limited to this. For example, the collecting unit, the transmitting unit, the receiving unit, and the analyzing unit in this specification may be realized by only hardware, only software, or a combination of hardware and software, in addition to being realized by the collecting function, the transmitting / receiving function, and the analyzing function described in the embodiment.

[0121] The term "processor" used in the description of the above-mentioned embodiment means a circuit such as a central processing unit (CPU), a graphics processing unit (GPU), an application specific integrated circuit (ASIC), a programmable logic device (e.g., a simple programmable logic device (SPLD), a complex programmable logic device (CPLD), and a field programmable gate array (FPGA)). Here, instead of storing a program in a memory, the program may be directly embedded in the circuit of the processor. In this case, the processor realizes its function by reading and executing the program embedded in the circuit. In addition, each processor in the present embodiment is not limited to being configured as a single circuit for each processor, and may be configured as a single processor by combining multiple independent circuits to realize its function.

[0122] Here, the medical image processing program executed by the processor is provided by being pre-installed in a ROM (Read Only Memory) or memory. The medical image processing program may be provided by being recorded in a computer-readable non-transient storage medium such as a CD (Compact Disk)-ROM, a FD (Flexible Disk), a CD-R (Recordable), or a DVD (Digital Versatile Disk) in a format that can be installed in these devices or in a format that can be executed. The medical image processing program may be provided or distributed by being stored on a computer connected to a network such as the Internet and downloaded via the network. For example, the medical image processing program is composed of modules including each of the above-mentioned processing functions. As actual hardware, a CPU reads out the medical image processing program from a storage medium such as a ROM and executes it, so that each module is loaded onto a main storage device and generated on the main storage device.

[0123] In addition, in the above-mentioned embodiment and modified examples, each component of each device shown in the figure is a functional concept, and does not necessarily have to be physically configured as shown in the figure. In other words, the specific form of distribution or integration of each device is not limited to that shown in the figure, and all or a part of it can be functionally or physically distributed or integrated in any unit according to various loads, usage conditions, etc. Furthermore, all or any part of each processing function performed by each device can be realized by a CPU and a program analyzed and executed by the CPU, or can be realized as hardware using wired logic.

[0124] Furthermore, among the processes described in the above-mentioned embodiments and modifications, all or part of the processes described as being performed automatically can be performed manually, or all or part of the processes described as being performed manually can be performed automatically by a known method. In addition, the information including the processing procedures, control procedures, specific names, various data and parameters shown in the above documents and drawings can be changed arbitrarily unless otherwise specified.

[0125] According to at least one of the embodiments described above, appropriate measures can be taken after the medical images are collected.

[0126] Although some embodiments have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.
