要求には応じることができなかった。2. Description of the Related Art In a conventional on-vehicle fluoroscopic imaging table, there is an axis center on which the fluoroscopic imaging table is moved up and down outside a mounted quick-cut section.
The trajectory of the up-and-down movement becomes compact because the trajectory moves around the axis, but the depth of the fluoroscopic imaging table, which requires a leg for holding the up-and-down center axis provided outside the quick-copy section, is increased. There is a drawback, when this fluoroscopy table is mounted vertically, there is no space for other units on the side of the side where the fluoroscopy table is stacked, and at the same time it meets the request to install a chest imaging device I couldn't do that.

る。When the fluoroscopic imaging table for an X-ray vehicle is moved up and down, the length direction is set to 23 times the inside width of the bus.
By increasing the depth to about 1400 mm from the current level of about 1700 mm to about 1400 mm while allowing horizontal stacking to be less than or equal to 00 mm, space efficiency can be increased by allowing the chest imaging device to be stacked on the side at the same time even when stacked horizontally It is an object of the present invention to provide a fluoroscopic imaging table capable of performing the following.

体を移動することによって達成される。SUMMARY OF THE INVENTION The object of the present invention is to provide a slide base for moving the entire fluoroscopic imaging table to the head side when standing up and moving the entire fluoroscopic imaging table to the foot side when tilting upside down, It is considered that the moving distance in the vertical direction of the fluoroscopic imaging table can be shortened, and this is achieved by moving the whole of the fluoroscopic imaging table at the time of raising and lowering with this slide base.

よりもコンパクトになる。When the entire fluoroscopic table is moved up and down simultaneously, the entire fluoroscopic table is moved to the head side when standing and to the foot side when tilted upside down to minimize the range of movement during tilting and the legs. Since it can be installed under the rapid-moving section, the depth is smaller than that of the conventional apparatus.

In some cases, there is a demand for shortening the car body and it is desired to mount other inspection equipment. Can be answered. In addition, even when mounted vertically in the bus, the chest imaging device and the like can be installed on the side of the see-through table, so that the inspection equipment can be easily arranged.

中心を持ってくれば良いことがわかる。FIG. 1 shows the minimum components of a fluoroscopy table. A table 1 on which a subject is placed, an X-ray tube device 2 for generating X-rays above the table 1, and a video system device 3 including an image intensifier for receiving the X-rays are used to reduce the trajectory of the fluoroscopy table. , It is sufficient to bring the X-ray tube apparatus 2, the image system equipment value 3, and the center of rotation near point A which is the center of the table 1.

跡は小さくなる。In the conventional perspective imaging table 2, a rotation center is provided below the table 1 of the perspective imaging table in FIG.
Is installed under the X-ray tube support 4, so that the depth dimension of the fluoroscopic table becomes small, but there is a disadvantage that the locus during the tilting operation becomes large. It can be seen that the X-ray tube device position 6 when standing and the X-ray tube device position 7 when reversely inclined (at −45 °) are outside the table 1 lateral width. To overcome this drawback, a mechanism has been devised for moving the entire fluoroscopic table by the difference between the X-ray tube apparatus in the upright and reverse tilt positions and the table in the horizontal position. By adding this mechanism, even if the actual center of rotation moves under the table, the entire fluoroscopic table moves, so the virtual center is point A in FIG. 1, and the locus of the fluoroscopic imaging table is reduced.

り透視撮影台全体が頭側方向に移動する。FIG. 4 is an external view of a fluoroscopic imaging table capable of moving the entire fluoroscopic imaging table in the longitudinal direction. A rack 9 is provided in the longitudinal direction of the slide base 8 of the perspective imaging table, and a chain (for moving the perspective imaging table) 12, a gear (large) 13, and a gear (small) are provided from an up / down drive motor 10, an up / down drive reducer 11. ) The rack 9 is driven via 14). When operating from the horizontal position to the standing position, the up / down drive reduction gear 11 rotates in the direction a in the figure, the chain 12 moves in the direction b, and the gear (large) 13
Is rotated in the c direction and the gear (small) 14 is rotated in the d direction, so that the entire fluoroscopic imaging table moves in the head side direction.

８が床に当たらずに済む。At the time of raising and lowering, the chain (for raising and lowering) 15 is set to e.
In this case, the tilting rotation shaft 16 is rotated in the direction f. The rotation frame 17 rotates in the direction f to start the rotation frame 17. If the rotation is continued as it is, the support frame 18 will hit the floor.
The chain (rotating frame) 20 moves in the g direction from 6 to the rotating frame planetary gear (upper) 19, and rotates the external gear of the rotating frame planetary gear (upper) 19 fixed to the rotating frame upper part 17 in the h direction. A support frame chain 22 is hung on a rotary frame planetary gear (upper) 19 and a rotary frame gear (lower) 21 provided above and below the rotary frame 17.
And the support frame chain 22 moves in the i direction, so that the support frame 18 moves in the head-side direction at the time of horizontal-to-standing operation.
8 does not hit the floor.

8 also moves in the foot direction, the virtual center of rotation is A in FIG.
It becomes a point, and the trajectory at the time of the fall and fall is almost within the width of the table 1.

ことができる。As described above, the depth of the perspective imaging table is made smaller than that of the conventional apparatus by using the perspective imaging table having such a mechanism while minimizing the trajectory at the time of tilting.
When mounted on an X-ray vehicle, the fluoroscopy table can be loaded in the lateral direction and the depth direction is short, so that the body length of the X-ray vehicle can be shortened. It is now possible to go to mountainous areas where it has been difficult to pass until now, and it is possible to increase the number of examiners. Even when stacked vertically, it is possible to simultaneously mount the chest imaging device on the side of the fluoroscopy table, eliminating the need to install it in another place as in the past, resulting in a shorter body, Many inspection instruments can be mounted, and the inspection efficiency can be increased.

When installed in a conventional imaging room, the installation space is small, so that it is possible to install a screening device, which has been increasing in recent years, in the room.

接触して壊す可能性が少ない。Since the conventional perspective imaging table has a large operating range when it is turned upside down, when a proximity console, a chair, or the like is placed near the perspective imaging table, it may come into contact with the upside down operation and be broken.
Even if various instruments are installed near the fluoroscopy table in the fluoroscopy table using this mechanism, it is easy to understand the tilting rotation range,
Less likely to break on contact.
