Description

Technical Field

[0001] The embodiments disclosed in this specification and the drawings relate to a medical information processing apparatus, a medical information processing method, a medical information processing program, and an examination support system.

Background Art

[0002] When attempting to image a patient with a medical imaging diagnostic apparatus, in many cases, a technician who operates the medical imaging diagnostic apparatus to perform imaging directly faces the patient to give explanations and perform procedures. Therefore, if one of the patient and the technician is infected with a virus or the like, there is a risk that the other will be infected with the virus. Therefore, in order to reduce the contact opportunities as much as possible, it is desirable for the technician to give explanations and instructions regarding imaging to the patient from a separate room. For this purpose, methods that do not involve contact between the technician and the patient, such as passing a tablet PC capable of displaying explanations about imaging to the patient and having the patient read the explanations by themselves, can be considered. However, in this case, it is necessary to disinfect and replace for each imaging, and furthermore, there is a possibility that elderly people, infants, etc. may not be able to operate the tablet PC. Also, a method of giving instructions via a mobile terminal owned by the patient can be considered, but there are problems such as restrictions on radio wave use in the hospital, and it is not practical.

Modes for Carrying Out the Invention

[0007] Hereinafter, a medical information processing apparatus, a medical information processing method, a medical information processing program, and an inspection support system according to this embodiment will be described with reference to the drawings. In the following embodiments, parts denoted by the same reference numerals perform the same operations, and redundant descriptions will be omitted as appropriate. Hereinafter, one embodiment will be described with reference to the drawings.

[0008] The inspection support system according to this embodiment will be described with reference to FIG. 1. The inspection support system according to this embodiment includes a medical information processing apparatus 1 and a plurality of display devices 2. The medical information processing apparatus 1 and the plurality of display devices 2 are connected via a network 5. The network 5 may be either wired or wireless.

[0009] The medical information processing apparatus 1 includes a processing circuit 10, a memory 11, an input interface 12, and a communication interface 13. The processing circuit 10 includes, for example, as hardware resources, processors such as a CPU (Central Processing Unit), an MPU (Micro Processing Unit), and a GPU (Graphics Processing Unit), and memories such as a ROM (Read Only Memory) and a RAM. The processing circuit 10 may also be implemented by an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), another complex programmable logic device (CPLD), or a simple programmable logic device (SPLD). The processing circuit 10 executes an acquisition function 101, a determination function 102, and a display control function 103 by a processor that executes a program deployed in the memory. Note that each function (acquisition function 101, determination function 102, and display control function 103) is not limited to being implemented by a single processing circuit. It is also possible to configure the processing circuit 10 by combining a plurality of independent processors, and each function may be realized by each processor executing a program.

[0010] The acquisition function 101 causes the processing circuit 10 to acquire information related to an examination to be presented to the subject. Further, the acquisition function 101 causes the processing circuit 10 to acquire state information of the subject. The state information is information for specifying the position and orientation of the subject, and is, for example, moving image data or image data captured by a camera in the examination room, and sensor values acquired by a so-called human sensor (pressure sensor, infrared sensor, etc.). The acquisition function 101 is an example of an acquisition unit. The determination function 102 causes the processing circuit 10 to determine the position and orientation of the subject based on the state information. The determination function 102 is an example of a determination unit. The processing circuit 10, according to the control function 103, switches and displays information related to the inspection on a display destination visible to the subject among a plurality of display destinations in response to a change in the orientation of the subject when the subject acts along the inspection flow. For example, according to the position and orientation of the subject determined by the determination function 102, among a plurality of display devices, information related to the inspection is displayed on the display device 2 that can be easily viewed from the orientation of the subject (the direction of the face). The processing circuit 10, according to the display control function 103, generates a graphical user interface for presenting information according to the display destination. The display control function 103 is an example of a display control unit.

[0011] The memory 11 is a storage device such as an HDD (Hard Disk Drive), an SSD (Solid State Drive), or an integrated circuit memory device that stores various information. In addition to HDDs, SSDs, etc., the memory 11 may also be a drive device that reads and writes various information to and from portable storage media such as CDs (Compact Discs), DVDs (Digital Versatile Discs), flash memories, and semiconductor memory elements such as RAMs (Random Access Memories). Note that the memory 11 is not limited to being included in the medical information processing device 1 and may be in an external storage device connected by the network 5. The memory 11 may store, for example, patient information, information related to the inspection, and information related to the graphical user interface to be displayed on the display device 2.

[0012] The input interface 12 receives various input operations from the user and outputs signals based on the received input operations to the processing circuit 10, the memory 11, the communication interface 13, etc. For example, a mouse, a keyboard, a trackball, a switch, a button, a joystick, a touch pad and a touch panel display, or a microphone for voice input, etc. can be used as appropriate. Note that in this embodiment, the input interface 12 is not limited to those equipped with physical operation components such as a mouse, a keyboard, a trackball, a switch, a button, a joystick, a touch pad and a touch panel display. For example, a processing circuit that receives a signal corresponding to an input operation from an external input device provided separately from the apparatus and outputs this signal to the processing circuit 10 is also included in the examples of the input interface 12. The communication interface 13 is a wireless or wired interface for communicating with other devices, and communicates with other devices via, for example, a hospital network.

[0013] The plurality of display devices 2 are respectively arranged at different positions in the examination room so that the subject following the examination flow can visually recognize them at each step. The display device 2 is, for example, a CRT display, a liquid crystal display, an organic EL display, an LED display, a plasma display, and any other display known in the art, a display-integrated computer such as a tablet PC or a notebook PC, or a projector. When the display device 2 is a projector, the content acquired from the processing circuit 10 is projected and displayed on the wall surface or the screen of the examination room. In the present embodiment, the "display destination" means, if the display device 2 is a display, the screen of the display, and if the display device 2 is a projector, the screen projected on the screen, the wall surface of the examination room or the bed by the projector. The display device 2 receives data related to the graphical user interface from the processing circuit 10 and displays the graphical user interface on the screen.

[0014] In FIG. 1, three display devices 2, namely a display device 2-1, a display device 2-2, and a display device 2-3, are shown. However, the number is not limited to three, and there may be four or more display devices 2. Further, for example, a display device 2 that can set a plurality of display destinations, such as a wide-angle projector that can display a screen at different positions in the examination room, or a display device 2 that can optically change the projection position by means of a lens, a mirror, an optical fiber, a prism, etc., may be a single display device 2. Also, if the display device 2 is a projector, the projector may be arranged on a remotely operable pan-tilt head, and the projection position may be changed by moving the pan-tilt head so that a plurality of display destinations can be set.

[0015] Next, an operation example of the medical information processing apparatus 1 according to the present embodiment will be described with reference to the flowchart of FIG. 2. Here, it is assumed that four display devices are arranged in the examination room, with a first display device near the entrance of the examination room, a second display device near the medical image diagnostic apparatus, a third display device on the ceiling directly above the medical image diagnostic apparatus, and a fourth display device near the exit of the examination room. Also, it is assumed that an examination is performed by a medical image diagnostic apparatus on which the subject lies down for examination, such as a CT apparatus or an MRI apparatus. As an initial state, it is assumed that the subject has reached near the entrance of the examination room.

[0016] In step S201, the processing circuit 10 by the display control function 103 displays, on the first display device which is the first display destination, subject information regarding the subject, such as the subject's name, date of birth, and gender, for the subject who has entered the examination room, by means of a graphical user interface. Note that the processing circuit 10 by the display control function 103 may cause the graphical user interface to display information including information regarding the imaging procedure by the medical image diagnostic apparatus arranged in the examination room.

[0017] In step S202, the processing circuit 10 determines, by the determination function 102, whether the subject has moved onto the examination table. Specifically, the processing circuit 10 determines, by the determination function 102, the position and orientation of the subject in the examination room from the status information acquired by the acquisition function 101. When the status information is the captured data (image data) captured by a camera, for example, using a learned model learned to enable object detection by a general machine learning method, the position and orientation of the subject and the medical imaging diagnostic apparatus are extracted from the image data, and if the distance between the medical imaging diagnostic apparatus and the subject is within the threshold value, it may be determined that the subject has moved onto the examination table. Alternatively, a camera may be installed in each display device, or a notebook PC, a tablet PC, etc. with a built-in camera may be used as the display device. Thereby, if there is a display device on which the subject is shown, it can be determined that the subject is present near the display device, and if the subject is not shown on the display device, it can be determined that the subject is not present near the display device. If it is determined that the subject has moved onto the examination table, the process proceeds to step S203. If it is determined that the subject has not moved onto the examination table, the process of step S202 is repeated until it is determined that the subject has moved onto the examination table.

[0018] In step S203, the processing circuit 10 displays, by the display control function 103, the examination information including information on the subject's body position for imaging located near the medical imaging diagnostic apparatus on the second display device which is the second display destination by means of a graphical user interface. Note that the processing circuit 10 may also cause the graphical user interface to display information including information on the imaging procedure by the medical imaging diagnostic apparatus arranged in the examination room.

[0019] In step S204, the determination function 102 causes the processing circuit 10 to determine whether the subject is lying on the bed (in a lying position). Whether the subject is in a lying position on the bed may be determined, for example, from the captured data captured by the camera in the same manner as in step S202, or a pressure sensor may be arranged on the bed, and when the value of the pressure sensor is equal to or greater than a threshold value and has a predetermined pressure distribution, it may be determined that the subject is in a lying position. If it is determined that the subject is in a lying position on the bed, the process proceeds to step S205. If it is determined that the subject is not in a lying position on the bed, the process of step S204 is repeated until it is determined that the subject is in a lying position on the bed.

[0020] In step S205, the display control function 103 causes the processing circuit 10 to display, on the third display device which is the third display destination, information regarding the subject's body position for imaging and information regarding the imaging procedure for the subject located on the bed by means of a graphical user interface.

[0021] In step S206, after the inspection is completed, the display control function 103 causes the processing circuit 10 to display, on the fourth display device which is the fourth display destination, inspection end information including at least one of guidance on the next inspection, post-inspection consultation, and accounting by means of a graphical user interface.

[0022] Note that in the example of FIG. 2, since it is clear that the subject leaves the examination room after the inspection is completed, it is assumed that the inspection end information is displayed on the fourth display device without any special determination. However, before step S206 after step S205, the processing circuit 10 may execute a process of determining whether the subject has moved to the exit of the examination room by the determination function 102. In the example of FIG. 2, it is assumed that the processing circuit 10 determines the position and orientation of the subject from the state information by the determination function 102 and determines the progress of the steps in the inspection flow, but it is not limited to this. For example, an engineer waiting in a separate room where the situation in the inspection room can be visually recognized may visually recognize the behavior of the subject and generate a trigger signal by pressing a button, for example. When the processing circuit 10 receives the trigger signal by the determination function 102, it may determine that the subject has advanced to the next step in the inspection flow.

[0023] Next, a specific processing example of the medical information processing apparatus 1 will be described with reference to FIGS. 3 to 6. FIG. 3 is a diagram showing a state when the subject S enters from the entrance 34 of the inspection room when about to undergo an inspection by a medical image diagnostic apparatus, that is, when the subject S enters the room.

[0024] A table is installed on the floor surface 31 of the inspection room, and a first display destination 35 is set on the table. Here, the first display destination 35 is assumed to be a display such as a monitor. In addition, a camera 38 for photographing the situation in the inspection room is arranged on the ceiling 32 of the inspection room, enabling the behavior and expression of the subject S to be photographed. It is assumed that the engineer who examines the subject S waits in a separate room outside the inspection room and gives instructions regarding the inspection flow to the subject from outside the inspection room while checking the video of the camera.

[0025] Note that the camera 38 is not limited to being installed on the ceiling 32, and the camera 38 may be arranged anywhere in the inspection room. If there is a window through which the situation in the inspection room can be confirmed from outside the inspection room, the camera 38 may be installed outside the inspection room and the inspection room may be photographed through the window.

[0026] On the first display destination 35, the subject information of the subject S is displayed by a graphical user interface. Specifically, information such as "(Subject Information) Name: A B, Date of Birth: January 1, 1970, Gender: Female" is displayed. By visually recognizing the first display destination 35, the subject S can confirm whether the displayed content is correct. Also, the graphical user interface may display instructions for the future examination flow and the next action. For example, an instruction such as "Please sit on the bed and look at the screen near the device" may be displayed or the technician may guide the subject verbally.

[0027] Furthermore, the graphical user interface may display the video of the technician waiting in a separate room who is in charge of the examination. By displaying a video in which the expression of the technician can be seen, the sense of unease of the subject S can also be alleviated.

[0028] Next, FIG. 4 is a diagram showing a state in which the subject S is sitting on the bed and visually recognizing the second display destination 36 near the bed. The second display destination 36 may be a wall-mounted display or may be realized by projecting a screen onto the wall surface by a projector.

[0029] When it is determined by the display control function 103 that the subject S has sat on the bed, the processing circuit 10 displays examination information on the second display destination 36 by a graphical user interface. As the examination information, a questionnaire may be displayed, and for example, a questionnaire such as whether there is an allergy to the contrast agent and confirmation of the physical condition may be conducted. Also, an instruction such as "Please lie on your back on the bed" may be displayed, and in addition to the display in words, a video representing the image of lying on the back may be displayed.

[0030] As for the timing of displaying information on the second display destination 36, for example, when it is determined from the video captured by the camera 38 that the subject S has moved from the first display destination 35, the display of information on the second display destination 36 may be started. Also, when a camera is arranged (or built-in) at the first display destination 35, when the subject S moves out of the viewing angle of the camera, the display of information on the second display destination 36 may be started assuming that the subject S has started moving in the direction of the bed. Note that by displaying information on the second display destination 36 before the subject S reaches the bed, it is also possible to guide the direction in which the subject S should move and the display device to be visually recognized.

[0031] Next, FIG. 5 is a diagram showing a state where the subject S is lying on the back on the bed and viewing the third display destination 37. The third display destination 37 may be a display installed or embedded in the ceiling, or may be realized by projecting a screen onto a wall surface by a projector.

[0032] When it is determined by the display control function 103 that the subject S is lying on the back on the bed, the processing circuit 10 displays inspection information on the third display destination 37 by means of a graphical user interface. As the inspection information, information such as the position information in the inspection, the inspection procedure, and the remaining time of shooting may be displayed. Specifically, in the case of an inspection that requires holding one's breath, an instruction such as "Please hold your breath when you receive a signal" may be displayed.

[0033] Also, a camera may be installed at the third display destination 37, the subject S on the bed may be photographed by the camera, and the photographed image may be displayed on the third display destination 37. Thereby, for example, when there is an instruction regarding the position such as raising or lowering the arm, it becomes easier for the subject S to judge whether the position is correct.

[0034] Next, FIG. 6 is a diagram showing a state where the inspection is completed and the subject S is viewing the fourth display destination 39 when leaving the inspection room. Regarding the fourth display destination 39 as well, it may be a wall-mounted display or may be realized by projecting a screen onto a wall surface by a projector.

[0035] In addition, in FIG. 6, since it is assumed that the entrance and exit of the examination room share the same door, the first display destination 35 and the fourth display destination 39 are shown as a common device. Note that this is not the only case. If the entrance door and the exit door are different, the first display destination 35 and the fourth display destination 39 may be set separately. Also, even if the entrance and exit share the same door, since the direction in which the subject S moves is opposite, the first display destination 35 and the fourth display destination 39 may be set at positions where they can be naturally visually recognized in the direction of the face along the movement of the subject S.

[0036] When it is determined by the display control function 103 that the examination has ended, the processing circuit 10 displays examination end information at the fourth display destination 39 by means of a graphical user interface. As the examination end information, information regarding guidance to the next examination room if there is a next examination, guidance for subsequent examinations, or guidance for accounting, etc. is displayed. Note that a map of the hospital grounds showing the location where the subject S should go next may also be displayed. Specifically, an instruction such as "~Thank you for your hard work~ Please go to Accounting No. 5" may be displayed.

[0037] In addition, a microphone for collecting the sound inside the examination room may be arranged in the examination room so that in a separate room where there is a technician, the voices of questions and complaints such as discomfort from the subject S can be obtained.

[0038] In the example of FIG. 5, it is assumed that the subject S lies on their back, but depending on the type of examination, there may be cases where it is necessary to take various postures. Therefore, it is desirable to arrange the display device so that the subject S can visually recognize the information in various postures on the examination table. An example of the arrangement of the display device corresponding to each posture will be described with reference to FIG. 7. A plurality of display devices are arranged so as to face the face direction corresponding to the position of the subject S lying on the bed 33. For example, if the subject S is in the right lateral decubitus position, the display destination 71b is set at a position facing the line-of-sight direction 71a of the subject S. Similarly, if the subject S is in the prone position, the display destination 72b is set at a position facing the line-of-sight direction 72a of the subject S. If the subject S is in the supine position, the display destination 73b is set at a position facing the line-of-sight direction 73a of the subject S. If the subject S is in the left lateral decubitus position, the display destination 74b is set at a position facing the line-of-sight direction 74a of the subject S.

[0039] Also, when it is necessary to take a plurality of positions in one examination, information may be displayed in advance on the screen of the display device corresponding to the position that the subject S should take, and an instruction such as "Please lie down in a direction where the display on which the information is displayed can be seen" may be given under the guidance of a technician or the like. Thereby, the subject S can easily grasp the position that should be taken. Further, based on the camera and the pressure sensor arranged on the bed, the position of the subject may be determined, and the display device 2 facing the direction in which the subject faces in the position may be specified and the screen may be displayed.

[0040] Next, another example of information display by the display device will be described with reference to FIG. 8. Not limited to displaying information on the screen of the display device, a projector may be used to project information related to the position on the bed. That is, by displaying image information related to the position of the subject S by so-called projection mapping, the position that the subject S should take becomes easier to understand. Further, the processing circuit 10 may project a moving image by the display control function 103.

[0041] FIG. 8 shows the situation before lying down on the hospital bed after entering the examination room. At this time, using the projector 81, an image regarding the supine position is projected onto the hospital bed 33. Thereby, for example, when performing an examination using a CT device, even if it is a supine position, it is necessary to specify whether it is so-called foot-first or head-first. Therefore, by projecting an image regarding the supine position onto the hospital bed 33 not only by the character information "Please lie on your back with your head entering the device first", the subject S can grasp the position to be taken at a glance.

[0042] Next, an example of the graphical user interface displayed on the display destination is shown in FIG. 9. As shown in FIG. 9, the display area of the graphical user interface includes a subject information and examination information display area 91, an examination flow display area 92, and a corresponding person image display area 93.

[0043] In the subject information and examination information display area 91, subject information such as the name and date of birth described above, and information regarding instructions for the subject such as examination procedures and positions are displayed. In the examination flow display area 92, information regarding the examination flow such as the examination order and the remaining time of the examination is displayed. For example, the order of the entire examination may be shown, and the current stage in the entire examination may be highlighted. In the corresponding person image display area 93, live images of technicians, nurses, etc. taken by a camera are displayed. Note that the arrangement of each area is not limited to this, and the display area may be further subdivided, and the size of the area may be set in any way.

[0044] Note that the information displayed by the graphical user interface may be changed according to the age and number of examinations of the subject. For example, when the subject is a child, the information may be displayed in hiragana notation and in an easy-to-understand expression. Also, for a subject who has undergone the same examination multiple times, such as a follow-up examination, for example, an explanation that is necessary for the first examination but can be omitted for the second and subsequent examinations may be omitted. More specifically, for example, the acquisition function 101 causes the processing circuit 10 to acquire the age of the subject, the determination function 102 causes the processing circuit 10 to determine that the subject is a child if the age is less than or equal to the threshold value, and the display control function 103 causes the processing circuit 10 to change the information regarding the examination to hiragana notation.

[0045] According to the present embodiment described above, in response to a change in the orientation of the subject when the subject acts along the inspection flow, the information regarding the inspection is switched to a display destination visible to the subject and displayed. As a result, by remotely guiding the inspection, the opportunity for contact between the subject and the technician can be reduced, and remote inspection can be supported. Further, by sequentially switching and displaying the information necessary for the inspection on a plurality of display destinations, for example, the equipment and places that the patient contacts are reduced, so that the disinfection frequency can be reduced.

[0046] In addition, each function according to the embodiment can also be realized by installing a program for executing the above processing in a computer such as a workstation and expanding them in the memory. At this time, the program that can cause the computer to execute the above method can also be stored and distributed in a storage medium such as a magnetic disk (such as a hard disk), an optical disk (such as a CD-ROM, DVD), or a semiconductor memory.

[0047] According to at least one of the embodiments described above, inspection can be supported remotely.

[0048] Although several 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, replacements, changes, and combinations of the embodiments can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope and gist of the invention, as well as in the invention described in the claims and its equivalent scope.
