2. Description of the Related Art At present, a so-called C is used as an image pickup means for picking up a medical image of a plurality of continuous tomographic images from a human body.
T (Computed Tomography) scanner and MRI (Magnetic R)
esonance Imaging) devices are used in the medical field, and various image display devices for displaying the medical images have been developed.

Such an image display device is realized, for example, by installing dedicated application software in a personal computer, and can sequentially display a plurality of consecutive medical images stored as series data on the display. However, in a general personal computer, since an input operation is executed by a keyboard or a mouse in which input keys such as alphabets are arranged, the versatility is good, but the operability is not good.

Therefore, the present applicant has filed Japanese Patent Application No. 2001-038.
The image display device filed as No. 522 includes a dedicated input operation device, and the input operation device includes an operation member that is slidable in the front-rear direction. In the image display device, when the operating member is slid in the front-back direction, the medical images displayed on the display are sequentially switched correspondingly, so that it is possible to easily browse the medical images of a plurality of continuous tomographic images. it can.

In particular, in the image display device of the above application, when the operating member is slid slightly from the initial position, the medical image is switched and displayed at low speed, and when it is slid to a large extent, it is switched and displayed at high speed.

A pair of side wall members 102 made of a flat metal plate are integrally fixed.

A base substrate 103 elongated in the front-rear direction is integrally fixed to the upper surface of the base member 101 located in the gap between the pair of side wall members 102, and the front and rear ends of the base substrate 103 are the base members. The front and rear edge portions of 101 respectively project outward. A support shaft 104 corresponding to a support mechanism is mounted at the center of the upper part of the pair of side wall members 102, and a rocking member 105 made of a rectangular metal flat plate elongated in the front-rear direction is formed in the front-rear direction by the support shaft 104. It is swingably supported on the.

On the upper surface of the swingable swinging member 105, an operating member 106 formed of resin in a flat rectangular parallelepiped shape elongated in the front-rear direction is integrally mounted. It is formed on one surface that smoothly communicates from the front end portion to the rear stage portion. Since the oscillating board 107 is integrally mounted on the lower surface of the oscillating member 105, the oscillating board 107 oscillatably supported in the front-rear direction faces the base board 103 at a predetermined interval from above. .

However, even if the second load acts on one end portion of the operating member 106 as described above, an error occurs in the operation timing of the two sensor elements 111 mounted on both end portions of the base substrate 103. there is a possibility. Therefore, in the input operation device 100 of the present embodiment, for example, the basic substrate 103

Such software is pre-installed in the image display device 300, and when the image display device 300 is activated, the CPU 3
The data is read at 01.

As described above, when the CPU 301 reads the appropriate computer program data and executes various processes, the image display device 300 of the present embodiment, as shown in FIG. 9, the image acquisition means 321 and the image storage means 322. , Image display means 323, image switching means 324, etc. are logically provided as various functions.

The image acquisition means 321 is a CPU corresponding to a computer program stored in the RAM 304.

As shown in FIG. 11, the medical image displayed by the image display means 323 is displayed. The images are sequentially switched in the front-rear direction in accordance with the swinging operation of the operation member 106 of the control unit 200 in the front-rear direction.

More specifically, when the front end portion of the operation member 106 is pressed by the first load, the medical image of the displayed series data is switched to the forward direction at a low speed,
Furthermore, when the front end portion of the operation member 106 is pressed to the second load from this state, the medical image is switched at high speed in the forward direction.

Similarly, when the rear end portion of the operation member 106 is pressed by the first load, the medical image of the displayed series data is switched to the backward direction at a low speed, and further,
When the rear end portion of the operation member 106 is pressed to the second load from this state, the medical image is switched in the backward direction at high speed.

CPU30, which is realized by utilizing hardware such as the CPU, is the hardware corresponding to a computer program stored in an information storage medium such as the RAM 304.
It is realized by the function of 1.

Such a computer program is, for example, a process of receiving series data from the CT scanner 410 by the I / F unit 311, a process of storing the received series data in the HDD 305, and a process of storing the stored series data. Display of medical images 21
1, a process of switching the medical image to be displayed to a low speed in the front-rear direction in response to a swinging operation of the operation member 106 of the control unit 200 in the front-rear direction with the first load, and a swing with the second load. The software is stored in an information storage medium such as a RAM 304 as software for causing the CPU 301 or the like to perform processing operations such as high-speed switching processing in response to a dynamic operation.

The tomographic inspection method in the tomographic inspection system 400 of the present embodiment having the above-mentioned structure will be described below in order. First, the CT scanner 410 captures a plurality of continuous tomographic images from a human body of a patient (not shown), and the plurality of medical images are registered in the image display device 300 as series data.

When the series data is thus registered in the image display device 300, an operator (not shown) performs a predetermined operation on the control unit 200, whereby a medical image of the series data is displayed on the display 300. It The image display device 300 of the present embodiment includes the display 3
The basic operation is to display one medical image of one series data in 00, but as shown in FIG. 10, a pair of medical images can be displayed in parallel as an applied operation.

For example, when the series data using the contrast agent and the series data not using the contrast agent are imaged and registered from one patient, the medical images in which the tomographic positions of the pair of series data coincide with each other are arranged in parallel in the left-right direction. It is preferable to display and to switch and display the pair of series data in the same manner as one series data while keeping the pair of series data synchronized.

In such a case, as shown in FIG. 12, while the medical image of the series data is displayed (step S1), the front end portion of the operation member 106 of the input operation device 100 is pressed to the first load. Then (step S2), the medical image is switched to the forward direction at a low speed (step S2).
3) When the rear end portion is pressed to the first load (step S6), the medical image is switched to the backward direction at a low speed.
(Step S7).

Further, as described above, the front and rear ends of the operating member 106 are pressed to the first load (step S2,
S6), when the medical image is switched and displayed at a low speed in the front-rear direction (steps S3 and S7) and the operating pressure is further increased to the second load (steps S4 and S8), the switching speed of the medical image is changed. The speed becomes high (steps S5 and S9).

On the other hand, even when the operation member 106 of the input operation device 100 is manually operated as described above and the medical images are sequentially switched, the operation member 106 is automatically returned to the initial position when the manual operation is released. Input operation device 100
Since the signal output of 1 is stopped, the forward / backward movement of the medical image is instantaneously stopped.

When the medical image is switched and displayed at a low speed in the front-rear direction as described above, the displayed medical image is switched every time a predetermined time such as 1.0 (sec) elapses. By pressing the operation member 106 for a moment, only one medical image can be moved back and forth.

The image display device 300 of the tomographic inspection system 400 of the present embodiment can display on the display unit 211 a medical image of a plurality of continuous tomographic images taken from the human body by the CT scanner 410 as described above. The displayed medical image can be switched in the front-rear direction by swinging the single operation member 106.

Moreover, the switching speed of the medical image can be set to be switched between low speed and high speed depending on the operating condition of the single operation member 106, and by switching the manual operation of the operation member 106, the switching display of the medical image can be displayed. It can be stopped instantly. Therefore, the input operation device 100 of the present embodiment has good operability, and the image display device 300 of the present embodiment can comfortably browse medical images.

Moreover, in the image display apparatus 300 of the present embodiment, a pair of medical images associated with each other can be displayed in parallel on the display 211, and in that case, a pair of medical images can be simultaneously switched while being synchronized. , It is easy to compare and examine a pair of series data. Nevertheless, the operation key 2 of the input operation device 100
It is also possible to switch back and forth only one of the pair of series data as a processing target by a predetermined operation of 05, so that medical images can be freely browsed.

The operation member 106 of the input operation device 100 according to the present embodiment has an upper surface which is smoothly continuous from the front end portion to the retracted portion. For example, the front-back length is "50 (mm)",
The left and right width is "15 (mm)", and the maximum stroke at the front and rear ends is "3.
The size is about 0 (mm) ".

Therefore, as shown in FIG. 13, in the input operation device 100 of this embodiment, the operation member 106 can be easily rocked in the front-rear direction with only the fingertip while the position of the wrist is fixed. Since the fingertip can be moved back and forth smoothly and quickly on the surface of the operation member 106, the operability is extremely good.

Moreover, in the input operation device 100 of this embodiment, one sensor element 111 is attached to each of the front and rear ends of the operation member 106, and two sensor elements 111 are attached to each of the front and rear ends of the base member 101. Therefore, one type of sensor element 111 can easily and surely realize the two-step working load, and also suppress the increase in the number of types of parts to improve the productivity.

Further, two kinds of element sets in which the operating loads are set in two stages due to the difference in the number of juxtaposed members are provided on the base substrate 103 fixed to the base member 101 and the rocking substrate 107 fixed to the operating member 106. Since the devices are distributed and mounted, the two types of element sets having the two operating loads are efficiently arranged with a simple structure, and the productivity is further improved.

Particularly, in the input operation device 100 of this embodiment,
Since two sensor elements 111 are mounted on the base substrate 103 and one sensor element 111 is mounted on the swing substrate 107, the number of wirings of the flexible substrate 116 connecting the swing substrate 107 and the base substrate 103. Has been reduced,
Further, the productivity is good.

Moreover, in the input operation device 100 of this embodiment, the sensor element 111, which is a general commercially available part, detects the rocking return means for urging the operation member 106 to the initial position and the rocking operation of the operation member 106. Since the swing detecting means is realized, the structure is simple and the productivity is good.

It should be noted that the present invention is not limited to the above embodiment, and various modifications are allowed without departing from the scope of the invention. For example, in the above-described embodiment, the CT scanner 410 is used to capture a tomographic image of a human body.
It is also possible to take an image with an I device (not shown).

Further, in the above-mentioned embodiment, it is exemplified that the medical images of a pair of different series data are displayed in parallel.
For example, it is possible to display a pair of medical images with different front and back positions of one series data in parallel,
It is also possible to display one medical image in plural by different image processing.

Further, in the above embodiment, the image display device 300
Exemplifies displaying a pair of medical images in parallel in the left-right direction on the display unit 211, but it is of course possible to display only one medical image, and it is also possible to display two or more medical images. It is possible.

In the above embodiment, the image display device 300 exemplifies that the medical image displayed on the display unit 211 is switched by the single input operation device 100 of the control unit 200. It is also possible to arrange the input operation devices 100 side by side and individually switch a plurality of medical images displayed in parallel.

Further, in the above embodiment, the image display device 300
Exemplifies that the switching speed of the medical image of the series data displayed on the display unit 211 is changed according to the input operation of the input operation device 100. However, in this case, the number of medical images of the series data displayed is small. In this case, the switching display ends in a short time, and if there are a large number, it takes a long time.

Therefore, it is also possible to set the time for switching and displaying the medical image of the series data from the beginning to the end in a plurality of stages, and select this time by the input operation of the input operation device 100. In that case, for example, when the first time is selected by the input operation of the input operation device 100, the medical images of the series data are switched and displayed from the beginning to the end at the first time, regardless of the medical images. You can browse the series data at a predetermined time.

Even in such a case, the maximum speed of the switching display has an upper limit. Therefore, when the switching display cannot be completed within the set time because the medical images of the series data are larger than the allowable range, the switching display is terminated halfway. It is preferable to extend the display time without performing any operation or thinning out medical images.

Further, in the above embodiment, the CPU corresponding to the computer program stored in the RAM 304 or the like is used.
It has been illustrated that various means are logically realized as various functions of the image display apparatus 300 by the operation of 301. However, each of such various means can be formed as unique hardware, and a part of the means can be stored as software in the RAM 304 or the like and a part can be formed as hardware.

In the above embodiment, the manual operation of the operating member 106 of the input operating device 100 is assumed by assuming the proper size, but for example, the operating member 106 is enlarged and the input operation is performed on the sole. It is also possible to do so. Further, in the above-described embodiment, it is assumed that the upper surface of the operation member 106 is a flat surface, but it is possible to further improve the operability by forming this into a concave surface that is curved downward in the front-rear direction.

Further, in the above-described embodiment, the input operation device 100 in which the upper surface of the operation member 106 is a smooth one surface that is manually operated with a fingertip has been exemplified. However, for example, as in the input operation device 500 illustrated in FIG. It is also possible to mount the operation member 501 formed as above on the swinging member 105 and manually operate it with fingers.

Further, in the above embodiment, the flat plate-shaped base member 1 is used.
01 and the oscillating member 105, the input operation device 100 in which the sensor elements 111 are arranged at both ends has a simple structure and the vertical thickness is shortened. However, like the input operation device 510 illustrated in FIG. It is also possible to arrange the sensor elements 111 on the front and rear outer surfaces of the lower end portion of the T-shaped swinging member 511 and the front and rear inner surfaces of the concave base member 512.

Further, the input operation device 52 illustrated in FIG.
As in 0, the sensor elements 111 are arranged on the front and rear outer surfaces of the lower end portion of the vertically long rocking member 521 and the front and rear inner surfaces of the concave base member 512, and the operation is formed as a joystick on the upper end portion of the rocking member 521. By mounting the member 501, it is possible to realize a structure in which the front-rear width of the entire device is shortened.

Further, in the above embodiment, the number of sensor elements 111 mounted on the base member 101 and the number of sensor elements 111 mounted on the operating member 106 are made different so that one type of sensor element 111 realizes a two-step working load. However, for example, two types of sensor elements (not shown) having different working loads are attached to the both ends of the base member 101 and the operating member 106, respectively, to realize a two-step working load. It is also possible to do so.

Further, one kind of sensor element 111 is attached to each of both end portions of the base member 101 and the operating member 106, and a metal spring or a metal is provided between one of the base member 101 and the operating member 106 and the guide member 112.

However, it is possible to realize a two-step working load.

In the structure in which the number of the sensor elements 111 of one kind arranged in parallel is different, the number of expensive sensor elements 111 used increases, but the type of parts and the manufacturing process can be reduced. In the structure using a plurality of types of sensor elements, the number of types of parts is increased, but the number of parts can be reduced, and the sensor convex portions of the facing sensor elements can be directly brought into contact with each other to omit the guide member 112. it can.

In the structure in which one kind of sensor element 111 is combined with the elastic member, the number of parts, the number of parts, and the manufacturing process increase, but the number of parts and the number of used expensive sensor elements 111 can be reduced. . That is, since the above-mentioned three types of structures have advantages and disadvantages, it is preferable to select the most suitable one in consideration of various conditions when actually manufacturing a product.

In the above embodiment, one type of sensor element 1 is used.
In order to realize a two-stage working load with 11, the base member 10
1 and the number of attachments to the operation member 106 are different, but one kind of sensor element 111 is provided on each side of the base member 101 and the operation member 106 like the input operation device 530 illustrated in FIG. It is also possible to realize a two-step working load by arranging the positions at different distances from the swing center. In this case, since the sensor elements 111 mounted on the base member 101 and the operation member 106 do not face each other, it is preferable that the swingable guide member 531 is commonly brought into contact with these sensor elements 111.

When the sensor element 111 is brought closer to the center of swing as described above, the operating load at the end of the operating member 106 decreases and the stroke increases. In other words, by varying the distance from the swing center of the sensor element 111, it is possible to adjust the working load and stroke at the end of the operating member 106.

Further, in the above embodiment, the sensor element 11 is provided at both end portions of the operating member 106 which is swingably supported at the central portion.
However, it is also possible to dispose the sensor element 111 at the other end portion of the operation member (not shown) which is swingably supported at one end portion.

Further, in the above-described embodiment, the sensor element 111, which is a general commercially available component, provides the swing return means for urging the operating member 106 to the initial position and the swing detecting means for detecting the swing operation of the operating member 106. Although the realization is illustrated, it is also possible to form the rocking return means and the rocking detection means by a dedicated mechanism.

Further, in the above embodiment, the sensor element 111 is mounted on the base member 101 and the operation member 106 to realize a two-step working load with an efficient structure. It is also possible to realize an operating load of three or more steps by setting the number of steps to three or more.

In the above embodiment, the sensor element 111 for detecting the presence / absence of the pressing operation with one operating load is used as an example. However, since the sensor element 111 is currently used for a shutter switch of a digital camera, the operating load is A sensor element set in two stages is also commercially available.

Therefore, for example, such a sensor element having a two-stage operating load is mounted on the operating member 106, and the sensor element 111 having a one-stage operating load is attached to the base member 101.
It is also possible to realize a three-step working load with two sensor elements by mounting it on the.
