本発明はX線透視撮影台の制御方式に係シ、特に映像系
装置部と天板部とが双方とも被検体の体軸方向へ移動可
能な透視撮影台の操作性向上に関するものである。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a control system for an X-ray fluoroscopic imaging table, and in particular, the present invention relates to a control method for an X-ray fluoroscopic imaging table, and in particular, a system in which both an imaging system unit and a top plate are movable in the body axis direction of a subject. This invention relates to improving the operability of a fluoroscopic imaging table.

た。この方式では。In the conventional apparatus as described above, the movement of the imaging system unit and the top plate in the body axis direction of the subject (hereinafter referred to as vertical movement) is either at different speeds or at the same speed. In this case, each individual had to perform an evacuation operation to prevent contact with the floor. In this method.

5を距離Sだけ移動しなければならない。When the operator raises and lowers the top while observing the perspective image, when some of the parts come to a position where they are likely to touch the floor, they move separately (only the parts that are likely to touch the floor move). ), the affected area was removed from the transparent field of view, and the operator had to perform a new movement operation to align one of them with the other. This will be explained using drawings. In FIG. 2, the top plate 5 is held in a horizontal position while observing the affected area 8a. Clearance A between the video equipment section and the floor surface
is a distance that is appropriate when in a horizontal position, but if it is further tilted in the opposite direction, it will come into contact with the floor surface. Therefore, conventionally, when the operator operates in the reverse tilting direction, the imaging system unit 9 is automatically moved toward the foot side of the subject 8 (in the direction of arrow F), as shown in FIG. The reverse tilting operation was performed after setting the camera to a position where the clearance B between the video system section 6 and the floor surface was maintained appropriately. Since the imaging system unit 9 has moved by the distance S, the subject 8, that is, the top plate 5 must be moved by the distance S when observing the affected area 8a.

なければならなかった。FIG. 3 is a diagram in which the affected area 8a is positioned so that it can be observed at the center of the X-ray irradiation field. As described above, in the past, for example, when the video system unit 9 came into contact with the floor, only it was evacuated, so the operator had to perform an operation to move the top plate each time.
本発明は上記問題点を解決し、操作者の意思によらずに

。An object of the present invention is to solve the above-mentioned problems and provide a control system for an X-ray fluoroscopy table in which the positional relationship between the imaging system and the top plate does not change regardless of the operator's intention. do.

In some cases, this can be achieved by simultaneously moving the other side in accordance with the one that comes into contact with the obstacle.

The binion 4 is meshed with the safety gear 2, and by rotating the pinion 4, the top plate 5. The imaging system section 6, which is vertically movably supported by the top plate support section 3, is integrated with the X-ray tube device section 7 which faces the top plate 5 between the standing position (90°) and the reverse tilted position. It can be raised and lowered up to (-30°). X-ray tube device section 7 towards the affected area 8a of the subject 8
When performing fluoroscopic imaging diagnosis by converting the transmitted image of X-rays emitted from the camera into visible light using the imaging system 6, the operator operates the operation switch on the operation table (not shown) and sets it to the optimum position. Observe. In X-ray fluoroscopic diagnosis of the gastrointestinal system, in which barium sulfate is adhered to the inner wall surface of a cylindrical or spherical shape and an XIfslSi image must be observed, it is necessary to move the subject 8 from a standing position to a reverse tilted position. In this type of device, the positioning operation of the affected area 8a in the body axis direction is usually performed using the top plate 5.
This is done by integrating the imaging system section 6 and the X-ray tube device section 7 and moving the imaging system section 9 without moving the object (subject 8).

に対する患部のズレが発生してしまうがやむを得ない。In the present invention, the top plate 5 and the video system unit 9 are oriented in the same direction with respect to the top support portion 3 from the reverse tilted position shown in FIG. 3 to the horizontal position shown in FIG. 4 to the standing position shown in FIG. By moving at the same speed, the affected area 8a can be observed at all times. For convenience of explanation, the operation of the conventional device is shown in Fig. 2.
As shown in the figures, when starting the operation of the present invention from the standing position shown in Fig. 1, passing through the reverse tilt position 3 and returning to the standing position, the affected area 8a is the center of observation as shown in Fig. 5. There is no deviation from the distance S. That is, as shown in FIG. 2, the top plate 5 and the video system unit 9 move in the direction of arrow F to an appropriate position in the same direction and speed, and then move to a reverse tilted position as shown in FIG. 3. From Figure 4 in the horizontal position to Figure 1 in the standing position
When making a diagram, the top plate 5 and the video system device 9 move in the same direction and speed in the direction of the arrow G shown in FIG. After moving to the position shown in Figure 1 in the standing position. In this method, although this does not occur in normal imaging of the gastrointestinal tract, it is possible that the top plate 5 and the imaging system unit 9 may not move to a predetermined position due to a difference in their vertical movement strokes. In this case, only the object that comes into contact with the floor will be evacuated, which will cause the affected area to shift with respect to the center of the imaging system, which is unavoidable.
本発明を実施するにあたり、両者の速度が問題となるが
、従来から被検体の乗る天板の速度は40〜50m+/
Sであり、映像系装置部の速度は40〜90 tyre

置部の移動速度を本発明の目的だけのために遅くすると

映像系装置の移動速度を可変速とし1通常の位置合わせ
時には高速移動可能としても良い。In carrying out the present invention, the speed of both is an issue, but conventionally the speed of the top plate on which the subject stands is 40 to 50 m+/
S, and the speed of the video equipment section is 40 to 90 tyre.
/S, so it is better to match it to about 50 pieces/S. Furthermore, increasing the speed at which the patient is moved is not a good idea because it increases the subject's sense of anxiety. Note that if the moving speed of the video system unit is slowed down just for the purpose of the present invention, the efficiency will drop to the level of normal positioning.
The moving speed of the video system device may be made variable so that it can move at high speed during normal positioning.
以上述べたように、映像系装置部と天板部の縦方向移動
速度を等しくして同時に作動させることにより従来装置
では操作者が意図しない映像のズレが生じたが5本発明
ではそのようなことがなく操作者は透視像の診断に専念
できる。As described above, in the conventional device, by setting the vertical movement speed of the video system unit and the top plate unit to be the same and operating them simultaneously, an image shift that was not intended by the operator occurred, but the present invention eliminates this problem. The operator can concentrate on diagnosing the fluoroscopic image.
