Opportunities for surgical procedures are increasing. This is not a conventional method in which only the subject is in the measurement room during measurement, and the operator does not perform various measurements or analysis of measurement images in the adjacent operation room, but rather in the immediate vicinity of the subject being measured. An operator, such as a doctor, or an attendant is placed in this area to perform various treatments. That is, an operation similar to the conventional X-ray imaging for the circulatory organ is performed in many diagnostic apparatuses such as an X-ray CT apparatus and an MRI apparatus.

In the IVR procedure, most of the time, the operator is occluded in both hands due to the procedure (surgical operation, etc.) of the subject, and the diagnostic apparatus cannot be operated to prevent infection. Therefore, it is necessary to leave the instructions to the caregiver to change the position of the imaged part or the patient's position, and to add measurement during the procedure or refer to the image, it is necessary to move to the adjacent operation room. Since he is in contact with the operator who is operating, he is not able to concentrate on his treatment because his work efficiency is poor.
Therefore, an IVR device that can be operated by an operator alone is desired.

[0004]

In the IVR treatment described in the above-mentioned prior art, various measuring instruments and diagnostic devices of different modalities are arranged around the bed on which the subject is placed, so that a sufficient space can be obtained. Therefore, each device array is separated from the operator, and it is difficult to confirm the operation and images.

According to the present invention, various medical image diagnostic apparatuses can be used for IV
It is an object of the present invention to provide a control device which is optimal for performing an R procedure and has good work efficiency.

[0006]

The display means of the head mounted display means and the second display means indicate that the specific control switch is selected on the virtual operation control panel. It is obtained by a means.

[0008]

The display means in the see-through type head mounted display (hereinafter abbreviated as HMD) displays a virtual operation control panel in which a plurality of control switches for defining the operation of the image diagnostic apparatus created on the computer are arranged. To be done. When an operator or an operator wearing the HMD (hereinafter referred to as an operator, etc.) makes a line of sight with a specific control switch of the virtual motion control panel displayed on the display means of the HMD, the sight line position is detected by the detection means, It is recognized that the specific control switch is selected from the information on the line-of-sight position and the coordinates of the control switch on the virtual motion control panel built in the computer. The selection of the specific control switch is displayed on the virtual operation control panel by a mark display or the like, and a control signal is generated so that the operation of the device corresponding to the control switch is performed. Therefore, the operator or the like can operate the image diagnostic apparatus without operating the actual control panel.

This measurement image is a display device 19 for the measurement room.
Will also be sent and displayed.

Image diagnostic apparatus of the present invention (X-ray fluoroscope)
In addition to the above-mentioned image processing device 14 as a control mechanism of the device, is equipped with a mechanism that enables an operator or the like to control the entire device in the measurement room. This mechanism is attached to the head of a surgeon or the like, and is connected to the display device 2 and a see-through HMD 1 having a display device 2 and eye sensors 3 to 6 which are detection means for detecting the line-of-sight position of the surgeon or the like. A display control device 11 for displaying a virtual motion control panel on the display device 3, and an eye sensor measurement control which is connected to the eye sensor, measures the line-of-sight position of an operator or the like by a signal from the eye sensor, and generates a signal corresponding to the line-of-sight position. The device 7 is connected to the display control device 11 and the eye sensor measurement control device 7, and it is recognized that the surgeon or the like has selected a specific control switch of the virtual motion control panel based on the input from the eye sensor measurement control device 7. , A virtual control panel control device 8 for controlling the display control device 11 to display that a specific control switch has been selected on the virtual operation control panel, and further according to the line of sight. Auxiliary switch 12 to confirm the selection of your switch to the final
Are connected to the virtual control panel controller 8.

The see-through type HMD1 is well known in the technical field of virtual reality (for example, WMD).
It is commercially available from Industries, Inc., and is externally worn as a glasses-type or helmet-type and is worn on the head of an operator or the like. The HMD 1 employed in the present invention has a part in the front direction of the line of sight of the HMD, for example, the lower half is covered with a transparent cover or lens to enable a forward field of view. A display device 2 such as a small liquid crystal display is arranged on the upper side), and an image can be displayed by receiving a video signal from the display control device 11. Although only one display device 2 is shown in the figure, it is also possible to provide the display device 2 on the left and right sides so as to enable stereoscopic viewing. Although not shown in FIG. 1, it is preferable to dispose a wide-field lens for viewpoint adjustment between the eyeball and the display device 2. By disposing such a wide-field lens, a small display surface can be obtained. Can be recognized in a larger and more distant direction (for example, a clear visual distance of about 20 cm).

Further, the HMD 1 is provided with an eye sensor mechanism for detecting the sight line of the operator. As this eye sensor, an infrared sensor, a magnetic sensor that evaporates a metal pattern on a contact lens to measure magnetism, a method of measuring an electric potential (EOG) when moving an eyeball, or the like can be used. An image sensor using infrared rays is preferable from the viewpoint of simplicity, and the illustrated eye sensor employs this. That is, the illustrated eye sensor mechanism is an infrared light emitting diode 3 that irradiates infrared rays toward the eyeball direction, a half mirror 4 that reflects infrared rays reflected from the cornea and retina of the eyeball, and a focus arranged in the infrared ray reflection direction. It is composed of an adjusting lens 5 and a small CCD camera 6. In this mechanism, for example, when an operator looks in the direction of the display device 2, the infrared light emitted from the light emitting diode 3 and reflected by the eyeball is partially reflected by the half mirror 4 arranged between the eyeball and the display device 2. The portion is further reflected and input to the small CCD camera 6 through the focus adjustment lens 5.
The CCD camera 6 sends the obtained eyeball image data to the eye sensor measurement control device 7.

The eye sensor measurement control device 7 analyzes the positional relationship between the binocular images based on the image data from the CCD camera 6 to determine the line-of-sight direction, and sends the line-of-sight direction data to the virtual control panel control device 8. Therefore, the eye sensor measurement control device 7 converts the eyeball image into a simple image by binarizing the white eye and the black eye,
The eye gaze direction is calculated by analyzing the iris positions of both eyes, and the eye gaze position is determined from the geometric relationship of the display system.

A virtual model 10 of a virtual motion control panel for controlling the operation of the X-ray fluoroscope is built on the virtual control panel controller 8 on a computer.
For example, a plurality of operation start switches (control switches) for selecting and starting a specific operation are arranged in advance.
Here, the control of the operation can basically include control of all operations of the image diagnostic apparatus. For example, the control of the bed apparatus 16 and the scanner 15 as the control for positioning the subject.
Control such as rotation of the lens and positioning of the X-ray tube, X-ray irradiation, control of measurement operation such as start or stop of imaging, image control, and the like. Therefore, the operation start switches are arranged in an appropriate positional relationship as having a function corresponding to these controls.
A plurality of control surfaces may be prepared in advance for each control.
The construction of a virtual model on a computer is applied as a virtual reality to an aircraft operation simulator, a three-dimensional stereoscopic game, and the like, and "a sense of population" (published by Nikkan Kogyo Shimbun) and "virtual reality" (technique). Published by Hyoronsha) etc.

Further, the virtual control panel control device 8 creates a line-of-sight point mark image model 9 at a position corresponding to the line-of-sight position of the virtual model based on the line-of-sight position data from the eye sensor measurement control device 7, and the virtual line-of-sight mark image model 9 is used. The switch selection progress model of the control panel model 10 is sent to the display control device 11 in real time. The display control device 11 performs processing such as conversion into a TV signal in order to visualize the switch selection progress model, and this image is displayed on the display device 2 such as the liquid crystal display of the HMD 1 as described above. That is, the display device 2 displays in real time the virtual model of the control panel built in the computer and the position of the line of sight on the control panel when the operation start switch of this control panel is selected. This display image is constantly displayed as a front view image to the operator or the operator, and the operator or the like confirms the movement of the control panel and the line-of-sight point mark displayed on the display device 2 while starting a specific operation. Switch can be selected.

Further, the virtual control panel control device 8 determines whether or not each control switch position of the virtual operation control panel model 10 and the viewpoint position match based on the line-of-sight direction data from the eye sensor measurement control device 7, and determines whether they match. Determines whether a particular control switch has been intentionally selected. Further, in order to further ensure the selection operation, an auxiliary switch 12 is connected to the virtual control panel control device 8, and a final confirmation is made in the process of discriminating whether or not a specific control switch is intentionally selected by this auxiliary switch 12. Can be used to As such an auxiliary switch 12, a switch such as a foot switch, a touch sensor, or a joystick can be adopted. When the virtual control panel control device 8 determines that a specific control switch is intentionally selected as a result of the determinations and determinations described above, the operation control of the X-ray fluoroscopic device corresponding to the switch selection is performed. A signal is generated, and the X-ray fluoroscopic apparatus main body (image processing apparatus 14, scanner 15, bed apparatus 1
6), and sends an operation signal. By this operation signal, movement control of the bed and scanner of the diagnostic device, image control such as image selection and display image change in the diagnostic device, and measurement control, etc. are basically performed in the diagnostic device itself. It is possible to do.

Next, one embodiment of the operation in such a configuration will be described with reference to FIG. In step 1, the control based on the line-of-sight of the virtual motion control board is made to function. The start-up menu and the like are displayed on the display device 2 or the display device 18 of the HMD 1,
19 is displayed and the console 13 of the main body device or the virtual control panel control device 8 is operated to start up. Next, in step 2, a desired operation menu is selected. Action menu 300
For example, as shown in FIG. 3, a plurality of control switch patterns for controlling the bed and scanner device, image control, and the like are prepared in advance as a menu. When the line-of-sight control of the virtual operation control panel functions in step 1, this operation is performed. The display device 2 and / or the display devices 18 and 19 of which the menu is the HMD 1
Is displayed in. These various control switch arrangements and combination menus are customized at each facility, and are modeled in the form of a plurality of line-of-sight control switch arrangements so that protocols can be selected. In order to select a desired control switch pattern (control surface) from the operation menu, the auxiliary switch 12 may be operated and determined, or may be input from the console 13 or the virtual control panel controller 8.

When the operation menu is determined in this way,
In step 3, the virtual control panel control device 8 sends the front view model data of the virtual control panel model 10 to the display control device 11. The display control device 11 performs processing such as conversion to a TV signal in order to visualize this model, and this image is displayed on the display device 2 and the display devices 18 and 19 of the HMD 1. For example, if the control menu 301 of the bed and scanner of FIG. 3 is selected as the operation menu, operation start switches corresponding to the left, right, up, and down movements of the bed are arranged on the control surface 400 as shown in FIG. There is.
When such a control surface is displayed on the display device 2, the see-through HMD wearer can confirm that the virtual motion control panel is set within the HMD field of view.

On the other hand, from the eye sensors 3 to 6 of the HMD 1, image data of the eyeball of the HMD wearer is always sent to the eye sensor measurement control device 7 in real time, and the eye sensor measurement control device 7 measures the eyeball position from this image data. Then, the line-of-sight position in the display system is determined, and the line-of-sight position data is transferred to the virtual control panel controller 8 (step 4).

The virtual control panel control device 8 arranges the line-of-sight mark image 9 at the position corresponding to the line-of-sight position on the control surface of the currently selected virtual control panel model 10 from the line-of-sight position measured in step 4. The image is displayed on the display device 2 via the display control device 11 (step 5). The measurement of the line-of-sight position by the eye sensor measuring device 7 in step 4 is periodically repeated, and the line-of-sight position is displayed in step 5 in almost real time.

In step 6, the virtual control panel control device 8 determines the line-of-sight position based on the position data thus transferred from the eye sensor measuring device 7 in real time.
It is checked whether or not it is in the 0 arrangement area, and if it is outside the area, the check is repeated.
This means that the actual line-of-sight control function has been operated.

In step 7, the virtual control panel controller 8 determines which switch position on the virtual control panel model the line-of-sight position is. At this time, in order to indicate that the position selected by the line of sight on the display device 2 is located in a specific switch section, it is preferable that only the switch section of the image model data is turned on or its brightness and color are changed. Therefore, the virtual control panel control device 8 changes to image model data in which lighting of the switch part in which the line of sight is stopped, brightness change, or color change, and the image data is sent to the display control device 11 to be displayed on the display device 2.
In FIG. 4, the switch 401 for upward movement of the bed of the control panel is lit. By seeing the image in which the switch state of the display device 2 has changed in this way, the HMD wearer can confirm the switch currently selected.

Depending on the control content, a plurality of models of the virtual operation control panel displayed on the display device 2 are prepared, and the input operation is possible by sequentially switching the control panel surface. For example, when the operation start switch for "moving the couch device" is selected, a virtual operation control panel on which the operation start switches indicating the direction and amount of movement of the couch device are arranged is displayed, and the newly displayed virtual display is displayed. A predetermined operation start switch of the operation control board can be selected.

In step 8, it is confirmed that the currently selected switch on the control panel is selected by the sensor wearer's intention prior to the start of the device operation of the selected switch. This is to prevent malfunction of the device due to accidental selection operation. As a method for determining the selection switch, various methods as exemplified below can be considered.

The first method is a method of starting the function of the switch only when the line-of-sight position and the position of the selection control switch are continuous for a certain period or more (referred to as a continuous period designation method). In the second method, after the switch is selected by the first continuous period designating method, another start switch is continuously selected so that the function of the operation start switch previously selected is started. To do. In this case, the start switch may be selected by continuously selecting the start switch 402 set on the same virtual control plane, or the function of this different start switch may be assigned to the start switch 402 by the external auxiliary switch 12. You may control it.

In step 9, the virtual control panel control device 8 receives the device operation start command in step 8 and sends an operation command (control signal) to the image processing device 14 which controls the overall control of the image diagnostic device. It should be noted that it is possible to directly issue a control command to the bed apparatus 16 itself in an operation in which the command signal is not related to control of the entire apparatus such as vertical movement of the bed.

In step 10, in response to this operation command,
Similar to the control by the console 13 or the like, the operation based on the command is performed. In step 11, if control is continued by virtual line-of-sight control, the process returns to step 6 and the operations of steps 6 to 11 are repeated. When ending the control on this virtual control panel, the end switch 403 arranged on the control surface is selected by the same method as the above switch selection procedure,
Display the operation menu 300, and the end menu 3
02 may be selected and the end key or the like may be executed, or an end command may be input at the main body operation console 13 to end the control function of the virtual control panel.

As described above, in the operation method of this configuration, the operator does not directly touch the device, and the same input operation as the panel operation or the input operation on the console 13 of the diagnostic device is controlled on the virtual control panel. Will be possible. Next, a second embodiment of the operation according to the present invention will be described with reference to FIG. The image diagnostic apparatus to which the second embodiment is applied is almost the same as the configuration of FIG. 1, but in this case, the image display apparatus 11 of FIG. Connect an external monitor such as a TV monitor. This external monitor is installed in the measurement room or the operation room side to display the same image as the display of the HMD, and informs the operator or the attendant in the measurement room or the operation room side of the switch selection and the operation command by the HMD wearer. I am trying. By this display, the operator or the caregiver performs an operation for controlling the device according to the intention of the HMD wearer.

That is, in the second embodiment, step 1
Up to 3 are the same as those in the first embodiment, but the control surface displayed on the display device 2 of the HMD by the selection of the operation menu is not only the control panel in which the control switches are arranged, but also the operator expected in advance. The message (operation command) may be arranged. The selection of the specific message on the control side is performed in the same manner as steps 4 to 7 of the first embodiment. That is, the eye sensor of the HMD always detects the line of sight of the HMD wearer, and when this line of sight coincides with the position of a specific message in the area of the control surface, the part of the message is turned on or the color or brightness is changed. It is displayed on the display device 2. Since this display is also displayed on the external monitor installed in the measurement room or the operation room side, the operator or caregiver reads the command of the operator who is the HMD wearer by the display on this external monitor, and follows this command. The operation start operation of the necessary device is performed by the operation console 13 or the virtual operation control panel control device 8
Is operated (step 8).

As described above, in the second embodiment, instead of the steps 8 and 9 of the embodiment shown in FIG. 2, a person other than the HMD wearer controls the actual operation panel according to the intention of the HMD wearer. After that, through the steps (9, 10) similar to the steps 10, 11 of FIG. 2, the control function by the line-of-sight control is repeated or finished. In the above embodiments, the case where the device itself currently used for diagnosis is controlled by the virtual control panel has been described, but the control device of the present invention uses the virtual control mechanism in combination with a plurality of diagnostic devices of different modalities. Is also possible. For example, in a diagnostic apparatus in which an X-ray fluoroscopic apparatus and a CT apparatus are combined, not only the X-ray fluoroscopic apparatus is controlled by the virtual control mechanism as described above, but also the operation of the CT apparatus arranged in the immediate vicinity thereof is controlled. Display device 2, 1
The IVR treatment can be performed while viewing the image display device of the CT device arranged near 8 and the measurement image of the X-ray fluoroscope together. In that case, the CT image control is performed while watching the virtual CT console display. Then, various combinations can be applied such as switching the CT images and performing the IVR treatment while referring to the CT images.

Further, the control device for an image diagnostic apparatus of the present invention can be applied not only to an X-ray fluoroscopic apparatus and a CT apparatus but also to any image diagnostic apparatus such as an MRI apparatus and an ultrasonic diagnostic apparatus.

[0034]

As is apparent from the above embodiments, according to the image diagnostic apparatus of the present invention, the virtual reality technique is adopted, and the operator or the like wears the see-through headmanted display and By providing an eye sensor for detecting the line-of-sight direction, the operator can control the device by viewing a specific control switch of the virtual operation control panel displayed on the display device of the headmanted display. In such a case, the operator or the caretaker can perform the measurement control and the image switching control, and the efficient measurement operation can be performed without interrupting the treatment work. In addition, since the operator does not directly touch the device during the operation, the device is prevented from being contaminated or infected by the adhered blood.

Further, the control device for controlling such a virtual operation control panel does not require the space around the operator as it should be, and the space around the various measuring devices and floor space necessary for the IVR or the like is treated or treated. It can be effectively used as a device space, workability can be improved, and work more devoted to treatment can be performed. Further, by mounting the see-through type headmanted display, it is possible to protect the operator's face and eyes from the blood bleeding from the patient without hindering the field of view of the operator to observe the patient.
