DETAILED DESCRIPTION

[0059] Hereinafter, the best mode for carrying out the present invention will be described with reference to the accompanying drawings.

[0060] [First embodiment]

[0061] Here, a case where the present invention is applied to an MRI apparatus will be described as an example.

[0062] [MRI device]

[0063] Figure 1 It is a diagram showing a schematic configuration of an MRI apparatus.

[0064] Figure 1 The MRI apparatus 1 shown has a gantry 10, a bed 20, an operating table 30, etc. The gantry 10 and the bed 20 are installed in an imaging room 2, and the operating table 30 is installed in an operating room 3. The imaging room 2 and the operating room 3 are separated by a partition 4. The partition 4 has a glass window 5. The situation in the imaging room 2 can be observed from the operating room 3 through the glass window 5.

[0065] The rack 10 has a hole 11 constituting an inspection space (photographing space). As an example, in the present embodiment, the rack 10 has a cylindrical hole 11 (having a so-called tunnel-type structure). In addition, the rack 10 can also adopt a so-called open-type structure. The subject S is inserted into the hole 11 and is inspected (photographed).

[0066] The gantry 10 has a static magnetic field magnet and a gradient magnetic field coil (not shown) in the frame. The static magnetic field magnet generates a static magnetic field in the hole 11. The static magnetic field magnet is composed of, for example, a permanent magnet, a superconducting magnet, a resistive magnet, etc. The gradient magnetic field coil is driven by a driving unit (not shown) to generate a gradient magnetic field.

[0067] The gantry 10 further includes a receiving coil 12. The receiving coil 12 receives magnetic resonance signals generated from the subject S. The receiving coil 12 is disposed at a portion of the subject S to be examined. Figure 1 An example is shown in which the inspection object is an elbow. The magnetic resonance signals received by the receiving coil 12 are reconstructed into an image and transmitted to the console 30 .

[0068] The bed 20 has a top board 21 on which the subject S is placed. The top board 21 is driven by a driving unit (not shown) to move horizontally and is inserted into the hole 11. The subject S is generally placed on the top board 21 in a supine position and inserted into the hole 11.

[0069] A screen 23 and a reflector 24 are provided on the reclining board 21. An image is projected onto the screen 23 from a projection device 22 provided in the photographic room 2. The projection device 22 projects the image onto the screen 23 from the back side (so-called rear projection). In addition, the projection device 22 may be arranged outside the photographic room 2, and the image may be projected onto the screen 23 using optical fibers or the like. The reflector 24 is arranged on the head of the subject S placed on the reclining board 21 in a supine position. The subject S observes the image (projected image) projected onto the screen 23 via the reflector 24. Therefore, the image projected onto the screen 23 is composed of a left-right inverted mirror image. The display unit composed of the projection device 22, the screen 23, and the reflector 24 is an example of a first display unit that can be visually recognized by the subject S under examination.

[0070] Figure 2 This is a block diagram showing an example of the hardware configuration of the console.

[0071] The console 30 receives an operation instruction from the operator Op, and operates the MRI apparatus 1 according to the received instruction.

[0072] The console 30 has a configuration as a general computer, that is, it includes a processor 31 , a main storage device 32 , an auxiliary storage device 33 , an input device 34 , a display device 35 , an interface unit 36 ​​, and the like.

[0073] The processor 31 is, for example, a general-purpose processor, namely a CPU (Central Processing Unit) that executes programs and functions as various processing units. Various programs and data executed by the processor 31 are stored in the main storage device 32 and / or the auxiliary storage device 33. The meaning of program is the same as software.

[0074] The main storage device 32 includes a RAM (Random Access Memory) and a ROM (Read Only Memory).

[0075] The auxiliary storage device 33 is constituted by, for example, a HDD (Hard Disk Drive), an SSD (Solid State Drive), or the like.

[0076] The input device 34 includes, for example, a keyboard, a mouse, a touch panel, an operation panel, and the like.

[0077] The display device 35 is constituted by, for example, a liquid crystal display (LCD), an organic EL display (OLED display), etc. The display device 35 is used for displaying various information, presenting images, and the like in addition to operating the MRI apparatus 1 .

[0078] The interface unit 36 ​​includes interfaces for connecting the gantry 10 , the bed 20 , and other peripheral devices, as well as a network interface for connecting the console 30 to a network.

[0079] Figure 3 This is a block diagram of the main functions of the operating console.

[0080] The console 30 mainly has functions of a photographing control unit 31A, an image acquisition unit 31B, a first display control unit 31C, a second display control unit 31D, a recording control unit 31E, etc. The functions of each unit are realized by the processor 31 executing a predetermined program.

[0081] The imaging control unit 31A controls the gantry 10 and the bed 20 to control imaging by the MRI apparatus 1 .

[0082] The image acquisition unit 31B acquires the captured image from the gantry 10. The acquired image is an image reconstructed from the magnetic resonance signal, and is a tomographic image of the subject S.

[0083] Alternatively, the console 30 may perform the reconstruction process. In this case, the console 30 acquires magnetic resonance signals from the gantry 10. The console 30 performs predetermined signal processing on the acquired magnetic resonance signals and reconstructs the acquired magnetic resonance signals into images.

[0084] The first display control unit 31C controls the display on the screen 23 by the projection device 22. As described above, the display on the screen 23 is observed by the subject S under examination. In the present embodiment, when the subject S is asked to perform a specific action, information on the action required of the subject S is displayed on the screen 23. The first display control unit 31C controls the display. The details of the control will be described later.

[0085] The second display control unit 31D controls display on the display device 35. The image obtained by shooting (the image generated by the image acquisition unit 31B) is displayed on the display device 35 under the control of the second display control unit 31D.

[0086] The recording control unit 31E controls recording of data in the auxiliary storage device 33. Images obtained by photographing are recorded in the auxiliary storage device 33 automatically under the control of the recording control unit 31E or in accordance with a recording instruction by the operator Op.

[0087] [On-screen display control]

[0088] As described above, the display on the screen 23 by the projection device 22 is controlled by the first display control unit 31C. When an examination requiring the subject S to perform a specific action is performed, the first display control unit 31C displays information on the action required of the subject S on the screen 23 .

[0089] The action required of the subject S varies depending on the examination. The first display control unit 31C acquires information about the examination to be performed, and controls the display on the screen 23 based on the acquired information so as to display information corresponding to the examination to be performed (information about the action required of the subject S in the examination).

[0090] Figure 4 This is a block diagram of the main functions of the first display control unit.

[0091] like Figure 4 As shown, the first display control unit 31C mainly has functions of a test information acquisition unit 31C1 , a display information acquisition unit 31C2 , and a display control unit 31C3 .

[0092] The inspection information acquisition unit 31C1 acquires information of the inspection to be performed (inspection information). In the present embodiment, the operator Op inputs the inspection information via the input device 34. Therefore, the inspection information acquisition unit 31C1 acquires the information input from the input device 34 as the inspection information. The inspection information is input by, for example, displaying a predetermined input screen on the display device 35.

[0093] The "examination information" includes at least "information on the examination target part". In this embodiment, information including "information on the examination target part", "information on the examination purpose" and "information on the action to be performed by the examinee" is acquired as the "examination information". In this embodiment, the examination information is an example of the first information.

[0094] Here, "information on the inspection target site" refers to information on the site of the body to be inspected (photographed), and the head, neck, elbow, shoulder, hip joint, knee, etc. correspond to this.

[0095] Furthermore, "information on the purpose of examination" refers to information on the purpose of examination, and includes functional MRI (fMRI) examination for brain function analysis, optic nerve examination, kinematic MRI (Kinematic MRI) examination for plastic surgery and the like.

[0096] Furthermore, "information on the action to be performed by the subject" refers to information on the action to be performed by the subject during the examination in each examination. For example, in a kinematic MRI examination of the elbow, the elbow is bent in a predetermined direction and angle and the image is taken. And, for example, in an optic nerve examination, the viewpoint is moved in a predetermined direction and the image is taken. In this way, the information on the action specified for each examination is included in the examination information as information on the action to be performed by the subject. The content of the action is specified as needed. For example, regarding the action of bending the elbow, knee, etc. (flexion, extension, etc.), the direction and angle of bending, etc. are specified. And, regarding the action of moving the viewpoint, the direction and amount of movement, etc. are specified.

[0097] Figure 5 It is a diagram showing an example of a screen for inputting inspection information. Figure 5 An example is shown in which “information on the inspection target site”, “information on the inspection purpose”, and “information on the action to be performed by the inspected person” are input as the inspection information.

[0098] like Figure 5 As shown, an input field for "Inspection object part" (an input field for information on the inspection object part), an input field for "Inspection purpose" (an input field for information on the inspection purpose), and an input field for "Action" (an input field for information on the action to be performed by the examinee) are provided on the screen, and information corresponding to the inspection to be performed is entered in each input field.

[0099] The input in each input field may be a method in which the operator Op inputs text, or may be a method in which predetermined options are displayed and the operator selects one from the displayed options to perform input. Figure 5 An example is shown in which predetermined options are displayed in a pull-down menu and required information is input by selecting one of the displayed options.

[0100] When the options are displayed to input the required information, the information of each item is input in a predetermined order, and preferably the display content of the options of the next item is switched according to the previous selection result. For example, the information is input in the order of "examination object part", "examination purpose", and "action to be performed by the examinee", and the display content of the options is switched according to the previous selection result for the items of "examination purpose" and "action to be performed by the examinee".

[0101] Figure 6 This is a diagram showing an example of the flow of setting options. Figure 6 An example is shown in which, in the case where "information on the inspection object part", "information on the inspection purpose" and "information on the action to be performed by the inspected person" are input as inspection information, the information is input in the order of "information on the inspection object part", "information on the inspection purpose" and "information on the action to be performed by the inspected person".

[0102] First, select the "Part to be inspected". Figure 6 In the example shown, "head", "neck", "upper limbs" and "lower limbs" are displayed as options for the parts to be examined. With respect to "upper limbs" and "lower limbs", more detailed parts are displayed. Specifically, with respect to "upper limbs", "elbows", "shoulders" and "others" are displayed as options for detailed parts. And, with respect to "lower limbs", "hip joints", "knees" and "others" are displayed as options for detailed parts.

[0103] Regarding "Inspection Purpose", the options to be displayed are determined by the selection result of "Inspection Target Part". Figure 6 In the example shown, when "head" is selected as the "examination target area", "fMRI" (functional MRI examination), "optic nerve" (optic nerve examination) and "MRA" (MRA (Magnetic Resonance Angiography) examination) are displayed as options for the examination purpose. Figure 6 In the example shown, when a site other than the "head" is selected as the inspection target site, the inspection purpose is automatically set to "kinematic MRI" (kinematic MRI inspection).

[0104] Also, regarding "Action", the options to be displayed are determined by the selection result of "Inspection Purpose". Figure 6 In the example shown, when "head" is selected as the examination target part and "fMRI" is selected as the examination purpose, "pat", "rest" and "other" are displayed as action options. Figure 6In the example shown, except when "head" is selected as the inspection target part and "fMRI" is selected as the inspection purpose, the action is automatically determined according to the selection results of the inspection target part and the inspection purpose. For example, when "neck" is selected as the inspection target part and the inspection purpose is "kinematic MRI", the action automatically becomes "nodding".

[0105] In addition, regarding "actions", even if they are the same type of actions, if their contents are different, they are processed as different actions. For example, even if they are the same "bending" action, if the bending direction, angle, etc. are different, they are processed as different actions (different bending actions).

[0106] The display information acquisition unit 31C2 acquires display information (information displayed on the screen 23 ) corresponding to the examination to be performed from a display information database (database: DB) 37 based on the examination information acquired by the examination information acquisition unit 31C1 .

[0107] Figure 7 It is a conceptual diagram of the information recorded in the display information database.

[0108] like Figure 7 As shown, the inspection information and the display information are recorded in a display information database 37 in a manner of being associated with each other. The display information database 37 is stored in the auxiliary storage device 33, for example.

[0109] In this embodiment, the display information is composed of data of images and / or texts displayed on the screen 23. The images include both still images and moving images. The details of the display information will be described later.

[0110] The display information acquisition unit 31C2 acquires corresponding display information from the display information database 37 based on the examination information acquired by the examination information acquisition unit 31C1. For example, when the examination information that the examination target part is "elbow", the examination purpose is "kinematic MRI", and the action is "flexion" is acquired, the information "DATE_0007" is acquired as display information from the display information database 37. In this way, the display information corresponding to the examination is acquired.

[0111] The display control unit 31C3 controls the projection device 22 to display the display information acquired by the display information acquisition unit 31C2 on the screen 23. In addition, as described above, in this embodiment, since the subject S observes the display of the screen 23 via the reflector 24, the image displayed on the screen 23 is composed of a left-right inverted mirror image.

[0112] As described above, in the present embodiment, information of the inspection to be performed (inspection information) is acquired, and display information corresponding to the acquired information is acquired from the display information database 37 and displayed on the screen 23 .

[0113] [Show information]

[0114] The information (display information) displayed on the screen 23 as information corresponding to the examination to be performed is information for causing the subject S to perform an action of the examination object part. When the action of the examination object part is performed by physically moving a specific part of the body, the display information contains information on the action of physically moving the specific part of the body. In this case, the display information contains information on the part of the body to be moved and information on the method of movement. For example, in the case of a kinematic MRI examination of the elbow, the action caused to be performed by the subject S is flexion of the elbow. Therefore, in this case, information indicating flexion of the elbow (information that the part to be moved is "elbow" and the method of movement is "flexion") is displayed on the screen 23 as display information. In the present embodiment, the display information is an example of the second information.

[0115] Figure 8 This is a diagram showing an example of display information. Figure 8 The display of the screen 23 is shown as viewed through the reflector 24. Therefore, the image actually displayed (projected) on the screen 23 is a left-right inverted image.

[0116] Figure 8 An example of information displayed when performing a kinematic MRI examination of the elbow is shown. In particular, Figure 8 An example is shown in which the subject S is caused to perform an action of bending the elbow 30 degrees upward from a horizontally extended state.

[0117] and, Figure 8 An example in which the action required of the subject S is displayed using text and illustrations is shown.

[0118] The text display instructs to bend the elbow 30 degrees upward from the horizontally stretched state. As an example, a text (message) of "Please bend the elbow 30 degrees upward from the horizontally stretched state." is displayed.

[0119] The illustration shows a diagram showing an action of bending the elbow 30 degrees from a horizontally stretched state to the upper side. Instead of the illustration, an animation showing an action of bending the elbow 30 degrees from a horizontally stretched state to the upper side may be used.

[0120] Regarding exercise methods, such as Figure 8 As shown, it is preferred to clearly indicate the start position and end position of the movement. Figure 8In the example shown, the position where the elbow is horizontally extended is the start position of the exercise, and the position where the elbow is bent 30 degrees toward the top is the end position of the exercise.

[0121] Here, Figure 8 The elbow information in is an example of the information of the part of the body to be exercised. Figure 8 The text and illustration are an example of information about exercise methods.

[0122] In this way, when the action required of the subject S is an action of moving a part of the body, it is preferable to use an illustration or animation to represent the action required of the subject S. This allows the subject S to easily understand the action he or she should perform.

[0123] When the inspection object is moved in stages and photographed multiple times, the display information is switched each time the image is taken. The display switching can be set to an automatic structure or a structure switched according to the instructions of the operator Op. When switching automatically, for example, it can be set to a structure that sequentially switches the display information using photography as a trigger.

[0124] Fig. 9 This is a diagram showing another example of display information.

[0125] Fig. 9 An example of display information is shown when the elbow is bent in stages and photographed a plurality of times in a kinematic MRI examination of the elbow. Fig. 9 The example is taken when the elbow is bent upward from the horizontal state by 30 degrees. More specifically, the example is taken when the elbow is stretched horizontally (0 degrees), bent by 30 degrees, bent by 60 degrees, and bent by 90 degrees.

[0126] In this way, when a part of the body is moved in stages and photographed, it is preferable to include information on each stop position in the display information. This allows the subject S to easily understand a series of actions that he or she should perform.

[0127] In addition, in an examination in which a part of the body is moved in stages and photographed, an auxiliary tool may be used. For example, in an examination in which the elbow is bent in stages and photographed multiple times as in the above example, an auxiliary tool that can bend the elbow at a certain angle interval may be used to photograph. In this case, information indicating the next angle of bending may be displayed as display information.

[0128] Fig.10 This is a diagram showing another example of display information.

[0129] Fig.10 An example of information displayed when the optic nerve is examined is shown. In particular, Fig.10An example is shown in which the action performed by the subject S is to move the viewpoint. Fig.10 As shown, the target object Ta is displayed on the screen 23. The target object Ta is an image that the subject S pays attention to during the examination. Fig.10 An example is shown in which the target object Ta is formed by an image imitating an eye. During the examination, the target object Ta is moved, for example, along a preset path. Alternatively, a configuration may be provided in which the target object Ta is moved by the operator Op. In this case, the operator Op moves the target object Ta using the display device 35 and the input device 34. The subject S performs an action of following the target object Ta with one eye or both eyes.

[0130] In this way, information on actions required of the subject S in each examination is displayed on the screen 23 as display information.

[0131] In addition to the above, for example, when the subject S is asked to perform a tapping motion during a functional MRI examination of the head, an illustration or animation of tapping the index finger is displayed. Similarly, when the subject S is asked to perform a hand clenching or releasing motion during a functional MRI examination of the head, an illustration or animation of the hand clenching or releasing motion is displayed. In addition, as in this example, the subject S may be asked to move a part different from the part to be examined depending on the purpose of the examination, etc. That is, the information for causing the subject S to perform the motion of the part to be examined includes information on the motion of physically moving a part of the body different from the part to be examined.

[0132] Furthermore, for example, when the subject S is caused to perform a calculation action in a functional MRI examination of the head, a calculation problem is displayed on the screen 23. For example, a problem is displayed in which the subject is caused to perform a calculation of subtracting 7 from 100 in sequence, such as "100-7=?", "93-7=?". In this way, the action performed by the subject S is not necessarily limited to physically moving a part of the body of the subject S. It also includes an action performed in the brain, such as the calculation action in this example. That is, the information for causing the subject S to perform the action of the examination object part includes information on the action performed in the brain.

[0133] [Function (operating method) of MRI device]

[0134] Fig.11 This is a flowchart showing the flow of inspection processing using an MRI apparatus.

[0135] First, the inspection information is acquired (step S1 ). As described above, in the present embodiment, the operator Op inputs necessary information from the input device 34 to acquire the inspection information.

[0136] When acquiring the examination information, information required for a general MRI examination (for example, subject information, etc.) is acquired.

[0137] After obtaining the examination information and the like, the subject S is set in the MRI apparatus 1. That is, the subject S is placed on the top board 21. After the setting is completed, the examination is started (step S2).

[0138] When the examination is started, first, general clinical images such as a positioning image and a preliminary measurement image are captured (step S3).

[0139] When the photography of general clinical images is completed, the photography corresponding to the examination content is started (step S3). At this stage, the information of the action required of the subject S (information for causing the subject S to perform the action of the examination object part) is displayed on the screen 23 (step S4). The first display control unit 31C obtains the display information corresponding to the acquired examination information from the display information database 37, and controls the projection device 22 to display the information of the action required of the subject S on the screen 23. The subject S confirms the display of the screen 23 and performs the required action.

[0140] The operator Op confirms the motion of the subject S and instructs the imaging. That is, when the subject S performs the required motion, the imaging is instructed. The imaging control unit 31A determines whether there is an imaging instruction from the operator Op (step S5). Then, the imaging is performed according to the imaging instruction (step S6).

[0141] After the photography, it is determined whether the photography required for the inspection has been completed (step S7). If it is determined that the photography required has been completed, the inspection is terminated.

[0142] As described above, according to the MRI apparatus 1 of this embodiment, when an examination is performed in which the subject S is required to perform a specific action, information on the required action is displayed on the screen 23. This allows the subject to be appropriately instructed on the action required of the subject S during the examination.

[0143] [Modifications]

[0144] (1) First display unit

[0145] In the above-mentioned embodiment, the following structure is set: the information of the action to be performed by the subject S is projected onto the screen 23 through the projection device 22, and the subject S observes the information projected onto the screen 23 via the reflector 24. The method of prompting the subject S with the information of the action to be performed is not limited to this. In addition, for example, the following structure can also be set: the information of the action to be performed by the subject S is projected onto the inner wall surface of the hole 11, the wall surface of the imaging room 2, etc. through the projection device 22. In this case, the subject S directly observes the image projected onto the inner wall surface of the hole 11, the wall surface of the imaging room 2, etc. In addition, the projection device 22 can also be set to project the information of the action to be performed by the subject S directly onto the position of the reflector 24 instead of projecting it onto the screen 23.

[0146] Furthermore, in the above-mentioned embodiment, the configuration using the projection device 22 is used, but a display device such as a liquid crystal display or an organic EL display may be used to present information about the action to be performed by the subject S to the subject S. In this case, the display device is arranged at a position that can be visually recognized by the subject S under examination. For example, a configuration may be provided in which a display device capable of position adjustment is provided on the frame 10 so that the subject S under examination can visually recognize various information.

[0147] Furthermore, in addition to or instead of displaying information on the action to be performed by the subject S on the screen 23 or the like, a configuration may be adopted in which the information is output by voice.

[0148] (2) Inspection content

[0149] In the above embodiment, functional MRI examination, optic nerve examination, kinematic MRI examination, etc. are described as examples of examinations performed using the MRI apparatus 1, but the application of the present invention is not limited thereto and can be widely applied to examinations in which the subject S is made to perform specific actions.

[0150] [Second embodiment]

[0151] In an examination in which a subject is made to perform a specific action, it is preferred that the subject can confirm whether the action performed by the subject is appropriate. In other words, it is preferred that the subject can confirm whether the action performed by the subject is in accordance with the requirements. In this embodiment, an MRI apparatus capable of confirming whether the action performed by the subject is appropriate is described.

[0152] [Device structure]

[0153] Fig.12 It is a functional block diagram of an MRI device.

[0154] like Fig.12As shown, the MRI apparatus 1 of this embodiment includes a camera 14. The camera 14 is a so-called digital camera that electronically photographs the subject (the subject in the bore) S under examination (see FIG. 1 ). Fig.13 ). The installation position of the camera 14 is not particularly limited. The camera 14 only needs to be installed at a position where the movement of the subject S in the hole can be confirmed based on its photographic image. Therefore, it is not necessary to be installed on the frame 10, and it can also be installed on the bed 20, etc. In addition, multiple cameras 14 can be installed. By installing multiple cameras 14, the movement of the subject S can be detected from various directions.

[0155] Furthermore, in the MRI apparatus 1 of the present embodiment, the console 30 further has the functions of a motion detector 31F and a determination unit 31G. The functions of the motion detector 31F and the determination unit 31G are realized by the processor 31 executing a predetermined program.

[0156] Fig.13 This is a block diagram of main functions of the motion detection unit, the determination unit, and the first display control unit.

[0157] The motion detection unit 31F acquires the image captured by the camera 14 and detects the motion of the subject S based on the obtained image. The process of detecting the motion based on the image can be performed by using a known technique. For example, the following method can be used: extracting feature points of the human body through image analysis and detecting the motion of the subject S based on the motion of the extracted feature points.

[0158] For example, feature points are extracted based on a skeleton model of the human body. Specifically, joint parts are extracted as feature points. For example, if the inspection object (photographic object) is an upper limb, the head, neck, right shoulder, left shoulder, right elbow, left elbow, right wrist, left wrist, etc. are extracted as feature points. And, if the inspection object is a lower limb, the right hip joint, left hip joint, right knee, left knee, right ankle, left ankle, etc. are extracted as feature points. In addition, when the inspection object is a head or neck, eyes, nose, ears, mouth, etc. can be extracted as further feature points.

[0159] Fig.14 This is a diagram showing an example of feature point extraction. Fig.14 The example in which the inspection object is the right elbow is shown. The image Im1 on the left side of the figure shows an example of an image taken when the elbow is horizontally stretched. And the image Im2 on the right side shows an example of an image taken when the elbow is bent about 60 degrees upward from the horizontally stretched state. Fig.14 As shown in FIG. 1 , the right shoulder, right elbow and right wrist are extracted from the image Im1 and the image Im2 as feature points. Fig.14 In FIG. 1 , symbol RS represents the feature point of the right shoulder, symbol RE represents the feature point of the right elbow, and symbol RW represents the feature point of the right wrist.

[0160] As shown in the images Im1 and Im2 , the movement of the elbow of the subject S can be detected based on the movement of the characteristic points RS, RE, and RW.

[0161] For the process of extracting feature points from an image, for example, a model that has been learned by machine learning so as to extract feature points from an image can be used.

[0162] In the present embodiment, the motion detection unit 31F that detects the motion of the subject S from the camera 14 and the image captured by the camera 14 is an example of the first detection unit.

[0163] The determination unit 31G determines whether the action required of the subject S has been performed based on the detection result of the action detection unit 31F. The determination unit 31G obtains the information of the action performed by the subject S from the display information acquisition unit 31C2. The display information acquisition unit 31C2 obtains the information of the action performed by the subject S from the display information database 37 together with the display information. Therefore, in the display information database 37, the information of the action performed by the subject S is recorded in a manner associated with the display information. The information to be recorded includes, for example, information on the part of the body to be moved and information on the movement method. In addition, the information on the movement method includes information on the start position of the movement and information on the end position of the movement. When a specific part of the body is moved in stages, the information on the movement method also includes information on the position where the part is stopped. For example, in the case of a kinematic MRI examination of the elbow, when the elbow is bent in stages and photographed at each position, as information on the action (flexion) performed by the subject S, (1) information on the direction of elbow bending, (2) information on the starting position (movement start position), (3) information on the step length (interval of bending angles), (4) information on the end position (movement end position), etc. are recorded. In addition, for example, in the case of a functional MRI examination of the head, when the subject S is made to perform a tapping action, (1) information on the duration (time for which the tapping action is continued), (2) information on the interval (time interval for performing the tapping action), etc. are recorded. And, for example, in a kinematic MRI examination of the neck, when the subject S is made to perform a nodding action, (1) information on the starting position (movement start position), (2) information on the step length (interval of bending angles), (3) information on the end position (movement end position), etc. are recorded.

[0164] The determination unit 31G refers to the information obtained from the display information acquisition unit 31C2, and determines whether the subject S has performed the required action based on the detection result of the action detection unit 31F. It is preferable to set an allowable range in the determination. For example, when the subject S is asked to perform an action of bending the elbow to a specified angle, the allowable range is set within a specified angle range around the target angle. When the elbow is bent within the allowable range, it is determined that the required action has been performed. The allowable range can be appropriately set according to the part of the inspection object, the purpose of the inspection, the content of the action, etc. In addition, it can also be set to a structure in which the operator Op can arbitrarily set the allowable range.

[0165] The display control unit 31C3 displays the determination result of the determination unit 31G on the screen 23 to notify the subject S thereof.

[0166] Fig.15 This is a diagram showing an example of display of determination results.

[0167] like Fig.15 As shown, the determination result is displayed superimposed on the display information. Fig.15 (A) is a diagram showing an example of a display when the requested action has been performed. In this case, the character "OK" is displayed as the judgment result. On the other hand, Fig.15 (B) is a diagram showing an example of a display when the requested action is not performed. In this case, the character "NG" is displayed as a determination result.

[0168] The display control unit 31C3 controls the projection device 22 so as to display the determination result superimposed on the display information.

[0169] [effect]

[0170] Here, the processing from detection of the motion of the subject S to output of the determination result will be described.

[0171] When the examination starts, the camera 14 takes an image of the subject S being examined. The image is taken at a predetermined frame rate. The time-series images taken by the camera 14 are sent to the motion detection unit 31F.

[0172] The motion detection unit 31F extracts feature points from the acquired image and detects the motion of the subject. The detection result is sent to the determination unit 31G.

[0173] The determination unit 31G acquires information on the action to be performed by the subject S via the display information acquisition unit 31C2. The determination unit 31G refers to the acquired information and determines whether the subject S has performed the required action based on the detection result of the action detection unit 31F. The determination result is sent to the display control unit 31C3.

[0174] The display control unit 31C3 displays the determination result on the screen 23 (see FIG. Fig.14 ).

[0175] Thus, according to the MRI apparatus 1 of this embodiment, the motion of the subject S is detected, and it is determined whether the required motion is performed. Then, the determination result is notified to the subject S. Thus, the motion required in the examination can be appropriately instructed to the subject.

[0176] [Modifications]

[0177] (1) Display of the subject's movement status

[0178] Information on the motion state of the subject S detected by the motion detection unit 31F may be displayed together with the display information. Thus, the subject S can easily grasp his or her own state and can more easily perform a desired motion.

[0179] Fig.16 FIG. 1 is a diagram showing an example of a display of the subject's motion status. Fig.16 , (A) shows an example of a display before a requested action is performed, and (B) shows an example of a display when the requested action has been performed.

[0180] exist Fig.16 In FIG. 3 , the current motion state of the subject S is represented by using points D1, D2 and lines L1, L2 based on the human skeleton model. Each point D1, D2 corresponds to a feature point detected by the motion detection unit 31F. Fig.16 In the example shown, point D1 corresponds to the feature point detected as the right elbow. Also, point D2 corresponds to the feature point detected as the right wrist. Also, line L1 as a link represents the right upper wrist, and line L2 represents the right forearm.

[0181] exist Fig.16 In (A), the black dots D1 and D2 and the solid lines L1 and L2 indicate the current motion state of the subject S. Furthermore, the white dot D2x indicated by the dotted line indicates the target position of the right wrist.

[0182] When the subject S has performed the required action, such as Fig.16 As shown in (B), the color of each point D1, D2 changes. For example, the point becomes white. At the same time, the character "0K" is displayed.

[0183] The display control unit 31C3 controls the display based on the detection result of the feature point by the motion detection unit 31F. In other words, each point and line is displayed corresponding to the position of each detected feature point.

[0184] In this way, by displaying the information of the current action state of the examinee S together with the display information, the required action can be more appropriately indicated to the examinee S. In addition, the examinee side can also more easily understand the required action. In particular, by displaying it together with the target position, it is easier to understand the required action. Thus, the examination can be smoothly implemented.

[0185] Fig.17 This is a diagram showing another example of the display of the subject's action status.

[0186] Fig.17 An example is shown in which the elbow is bent in stages and photographed multiple times in a kinematic MRI examination of the elbow. Fig.17 , an example of photographing the elbow while bending it upward by 30 degrees from a horizontally stretched state is shown. In this case, in addition to the information about the action performed by the subject S, information indicating the current state of the action of the subject S is also displayed. Similar to the above-mentioned modified example, in this example, the action state of the subject S is also displayed using points D1, D2 and lines L1, L2 based on the human skeleton model.

[0187] in addition, Fig.17 An example is shown in which the subject S bends his elbow to 60 degrees. In this case, the point D2x and line L2x representing the target position are displayed. In this way, when a part of the body is moved in stages, the target position is displayed in sequence. Thus, the subject S can be appropriately guided.

[0188] Fig.18 This is a diagram showing another example of the display of the subject's action status. Fig.18 An example of a case where the optic nerve is examined is shown, and an example of a case where the subject S is caused to perform an operation of moving the viewpoint is shown.

[0189] In this case, in addition to the information about the action that the subject S is to perform, information indicating the current state of the action of the subject S is also displayed. As described above, when the subject S is to perform an action of moving the viewpoint, the target object Ta that the subject S is to focus on is displayed as display information. In addition, as information indicating the current state of the action of the subject S, information indicating the current position of the viewpoint of the subject S is displayed. Fig.18 In FIG. 1 , the circular mark CP indicates the current viewpoint position of the subject S. The subject S can easily understand the position (the position of the target object Ta) to which the viewpoint should be moved by checking the position of the mark CP.

[0190] In this example, the camera 14 captures an image of the eyes of the subject S. The motion detection unit 31F detects the position of the pupil based on the image captured by the camera 14 .

[0191] (2) Guidance

[0192] Based on the detection result of the motion, guidance (including suggestion of improvement points) for the subject S to perform the required motion can be provided. In this case, the console 30 has a guidance function.

[0193] Fig.19 This is a block diagram of the functions of the operation console related to the guidance function.

[0194] like Fig.19 As shown in FIG. 1 , the console 30 has a function of a guide information generating unit 31H for generating guide information. This function is realized by the processor 31 executing a predetermined program.

[0195] The guidance information generating unit 31H determines whether to generate guidance information based on the determination result of the determining unit 31G. That is, when the determining unit 31G determines that the requested action is not performed, guidance information is generated.

[0196] The guidance information is information for the subject S to perform the required action, and is generated according to the current state of the subject S. The guidance information generating unit 31H generates the required guidance information according to the detection result of the action detecting unit 31F. That is, information (information for improving the current state) for guiding from the current state to the target state (position, posture, etc.) is generated. For example, in the case where the subject S is required to perform an action of bending the elbow 30 degrees upward from the horizontally stretched state, when the detected action of the subject S is an action of bending the elbow 20 degrees upward from the horizontally stretched state, information requiring further bending 10 degrees upward is generated as guidance information. And, for example, in the case where the subject S is required to perform an action of bending the elbow 30 degrees upward from the horizontally stretched state, when the detected action of the subject S is an action of bending the elbow 30 degrees diagonally upward from the horizontally stretched state, information requiring correction of the bending direction is generated as guidance information. In this way, information of the required action is generated according to the current state as guidance information. The expression form is not particularly limited. For example, it can be composed of text data that expresses the required action in an article. Furthermore, the data may be composed of data expressing a necessary action by illustration or animation instead of or in addition to the text data.

[0197] The display control unit 31C3 displays the guidance information generated by the guidance information generating unit 31H on the screen 23. As described above, the guidance information displays information for guiding the subject S from the current state to the target state. For example, in the above example, a message such as "Please bend your elbow further upward by 10 degrees" is displayed in text at a predetermined position on the screen 23.

[0198] In this way, by providing guidance or improvement points, the subject S can easily perform the required action. In addition, the subject can also easily perform the required action.

[0199] In this example, the guide information is displayed on the screen 23 , but in addition to or instead of the display on the screen 23 , the guide information may be output by voice.

[0200] (3) Notification of determination results, etc.

[0201] In the above embodiment, the determination result is displayed on the screen 23 to notify the subject S, but the method of notifying the determination result is not limited to this. In addition, for example, the determination result can also be notified using sound or voice. The same is true for the guidance information, and the guidance information can be notified to the subject S by voice.

[0202] (4) Determination method

[0203] Artificial Intelligence (AI) can also be used to determine whether the required action has been performed. For example, it is also possible to add the image captured by the camera 14 to the learning completion model to determine whether the required action has been performed. The learning completion model is generated by machine learning using prescribed learning data so that it can be determined from the image whether the prescribed action has been performed.

[0204] (5) Detection of the subject's movements

[0205] In the above embodiment, the camera 14 is used to capture the image of the subject S being examined and the motion of the subject S is detected based on the obtained image. However, the method of detecting the motion of the subject S being examined is not limited to this. For example, the motion of the subject S may be detected using the image captured by the MRI apparatus 1.

[0206] (6) Obtaining inspection information

[0207] In the above-mentioned embodiment, the operator Op manually inputs the information of the examination to be performed (examination information) via the input device 34, but the method of obtaining the examination information is not limited to this. Usually, in an MRI examination, the information of the subject, the information of the examination content, etc. are obtained (input) before the examination. Therefore, the examination information can be obtained using this information. In addition, this information can be obtained from the outside (for example, a system within a hospital, etc.) via a network. In addition, it can also be obtained from the imaging protocol.

[0208] [Third embodiment]

[0209] In the second embodiment, the motion of the subject S is detected, and the device automatically determines whether the required motion has been performed based on the detection result. In this embodiment, the detection result of the motion is presented to the operator Op, and the operator Op determines whether the motion is appropriate.

[0210] Fig. 20 This is a block diagram of the main functions of the operating console.

[0211] like Fig. 20 As shown, in the MRI apparatus of this embodiment, the information of the motion of the subject S detected by the motion detection unit 31F is sent to the second display control unit 31D. The second display control unit 31D displays the acquired information of the motion of the subject S on the display device 35. The display method is not particularly limited. For example, as in the above embodiment, the current motion state of the subject S can be displayed using points representing feature points and lines connecting the points (see Fig.16 ). At this time, the target state (position, posture, etc.) may be displayed together. In the present embodiment, the display device 35 is an example of a second display unit that the operator Op can visually recognize.

[0212] Thus, in the MRI apparatus of the present embodiment, the current action state of the subject S is displayed on the display device 35. Therefore, the operator Op can grasp the current action state of the subject S by checking the display device 35. Therefore, the operator Op can judge whether the required action has been performed based on the display of the display device 35. The operator Op notifies the subject of the judgment result as needed. For example, when the required action has been performed, its content is displayed on the screen 23 via the projection device 22 (for example, "OK" is displayed). And, when the required action has not been performed, the information required in the required action is notified. For example, information used to guide to the target position is notified.

[0213] [Modifications]

[0214] (2) Second display unit

[0215] In the above embodiment, the current motion state of the subject S is displayed on the display device 35 provided on the operation table 30, but the display destination of the current motion state of the subject S is not limited thereto. It may also be displayed on another display device located outside the imaging room 2. Therefore, for example, it may be displayed on a mobile terminal (e.g., a tablet computer, a smartphone, etc.) having a display.

[0216] (2) Information presentation to both the subject and the operator

[0217] The detection result of the motion of the subject S may be presented to both the subject S and the operator Op.

[0218] Furthermore, the apparatus may automatically determine whether the requested action has been performed based on the detection result of the action of the subject S, and notify the operator Op of the result. For example, the determination result may be displayed on the display device 35 to notify the operator Op.

[0219] Furthermore, a configuration may be adopted in which guidance information for the subject S to perform a required action is generated based on the detection result of the action of the subject S and notified to the operator Op.

[0220] [Fourth embodiment]

[0221] Generally, during an MRI examination, an emergency call button is handed to the examinee S. When feeling discomfort or inconvenience during the examination, the examinee S presses the button to notify the operator Op or the like. However, during an examination of a moving body part, the button may sometimes interfere with the examination. Therefore, in this embodiment, an MRI apparatus is described in which the examinee S during the examination can contact the operator Op or the like without using the emergency call button.

[0222] Fig.21 This is a block diagram of the main functions of the operating console.

[0223] like Fig.21 As shown, the console 30 also has the function of a specific action detection unit 31J. The specific action detection unit 31J analyzes the image captured by the camera 14 and detects a specific action performed by the subject S. Here, the specific action includes the subject S taking a specific posture (pose) and making a specific gesture (sign). For each action, the content of the meaning conveyed by the subject S to the operator Op and the like is specified.

[0224] Fig. 22 This is a diagram showing an example of the content of a specific action and the meaning to be conveyed.

[0225] Fig. 22 This shows an example of conveying the intention to interrupt the inspection. Fig. 22 In the example shown, the action (posture) of crossing the arms is assigned with the meaning of requesting an interruption check.

[0226] Furthermore, a negative (NO) meaning can be assigned to the action of shaking the head left and right, or a positive (YES) meaning can be assigned to the action of shaking the head up and down (nodding action).

[0227] The subject S is informed of the actions to be detected and the contents of the expressions of intent assigned to each action before the examination.

[0228] If a specific action is detected from the image captured by the camera 14, the specific action detection unit 31J outputs information about the detected action to the second display control unit 31D. For example, a learning model that has been machine-learned to detect a specific action from an image can be used to detect the specific action. In the present embodiment, the specific action detection unit 31J that detects a specific action performed by the subject S from the camera 14 and the image captured by the camera 14 is an example of the second detection unit.

[0229] The second display control unit 31D displays information corresponding to the motion detected by the specific motion detection unit 31J on the display device 35 and notifies the operator Op of the information. Fig. 22 In the example shown, when the specific action detection unit 31J detects an action requesting to interrupt the inspection (an action of crossing the arms), the second display control unit 31D displays a message "Interrupt inspection" on the display device 35 to notify the operator Op.

[0230] Thus, according to the MRI apparatus of this embodiment, when the subject S performs a predetermined specific action, information corresponding to the action is displayed on the display device 35. Thus, the subject S being examined can contact or communicate with the operator Op etc. without using an emergency call button.

[0231] [Modifications]

[0232] (1) Notification method

[0233] In the above embodiment, when a specific action is detected, information corresponding to the detected action is displayed on the display device 35 to notify the operator Op, but the method of notifying the operator Op is not limited to this. Instead of displaying on the display device 35 or in addition to displaying on the display device 35, information corresponding to the detected action may be output by voice or sound to notify the operator Op. In addition, the light may be turned off or on to notify the operator Op.

[0234] (5) Detection of specific actions

[0235] In the above embodiment, the camera 14 is used to capture an image of the subject S being examined and a specific motion is detected based on the obtained image. However, the method of detecting the specific motion is not limited thereto. For example, the specific motion may be detected using an image captured by the MRI apparatus 1 .

[0236] [Other embodiments]

[0237] (1) Processing unit that provides various functions of the console

[0238] The processing unit that provides each function of the console 30 can be composed of various processors. Among the various processors, in addition to general-purpose processors such as CPUs and GPUs (Graphic Processing Units), there are also processors such as FPGAs (Field Programmable Gate Arrays) that can change the circuit structure after manufacturing, i.e., programmable logic devices (PLDs), ASICs (Application Specific Integrated Circuits), etc., which have a circuit structure specially designed for performing specific processing, i.e., dedicated circuits, etc. A processing unit can be composed of one of the various processors, or it can be composed of two or more processors of the same or different types. For example, a processing unit can be composed of a plurality of FPGAs or a combination of a CPU and an FPGA. In addition, multiple processing units can also be composed of one processor. As an example of multiple processing units composed of one processor, the first is the following method: as represented by a computer used for a user end or a server, a processor is composed of a combination of more than one CPU and software, and the processor functions as multiple processing units. Second, there is a method in which a processor is used to realize the functions of the entire system including a plurality of processing units on a single IC (Integrated Circuit) chip, as represented by a system on chip (SoC).
