大きいことや、装置の大型化等の問題があ）、首振シ装
置の方が構造的に小型化できる。Compared to X-ray photography, the device using this semiconductor sensor reduces the exposure dose to 1/10-1/1oO and has good contrast resolution, so it is expected to be able to identify minute lesions and affected areas in the future. There is. A device using such a semiconductor sensor incorporates semiconductor sensors 41 in a row as shown in FIG. It performs a multi-swing motion. Also, bed 46
On the other hand, there is also a device (not shown) that moves the X-ray source 42 and the semiconductor sensor 41 in parallel. Among these devices, the device that moves the head in parallel has problems such as the amount of movement of the X-ray source 42 being larger than the oscillating device, and the device is larger), but the oscillating device can be structurally smaller. .

率は高く、いくらかの不安を与える。Problems to be Solved by the Invention The swinging device shown in FIG. 4 scans the human body in the height direction, and scanning in the lateral direction requires moving the shaft 43 away from the bed 45. As a result, the equipment becomes larger. Furthermore, scanning in the height direction requires a width of the semiconductor sensor 42 corresponding to the width of the human body, which requires approximately 6oα or more. Furthermore, when a subject lies on the apparatus, the irradiation part of the X-ray source 42 is always above the human body, so even if safety measures are taken, there is a high probability that the subject will be exposed to an unnecessary amount of X-rays, causing some anxiety.

２５を横切り、Ｘ線照射を行なう。An element array 1 in which elements sensitive to radiation are continuously arranged in a linear or curved arc shape is housed in a tray 2 and configured to be slidable on guide rails 3 with wheels 4. The tray 2 is driven by a linear movement table 5 using a ball screw, a motor, etc., which allows precise positioning. That is, the bar 7 is inserted into a rotatably supported linear bearing 6, and the table 5 moves linearly, so that the tray 2 moves in an arc along the guide rail 3. The connection between the X-ray source 8 and the linearly moving table 5 is achieved by first locking one end of the rotating plate 1o to the first pin 9 of the linearly moving table 5, and then locking the other end of the rotating plate 1o to the first pin 9 of the linearly moving table 5. The rotary plate 10 is locked by a shaft 11 and rotates as the movable table 6 moves. One end of the vertically moving plate 12 is connected to the second pin 13 on this rotating plate 1o.
The other end is locked to the third pin 16 of the vertical shaft 15 with the second support shaft 14 as the center. Vertical shaft 1
5 is supported by guide bearings 1 and 18 and is movable up and down.The upper part is engaged with the fourth bin 19 and one end of the oscillating plate 2o, and the other end is connected to the X-ray source 8. It is locked with the shaft 21 located at the line focus position. Further, the block 22 supporting the X-ray source 8 is configured to be slidable with respect to the column 23, and further,
The post 24 in which the fourth bin 19 is installed can slide on the vertical shaft 15. Screw 28 when in use
．． It was concluded on 29th. These blocks 22, post 24
Since the X-ray source 8 can be slid, it can be used, for example, to obtain a clear image by bringing the X-ray source 8 closer to or farther away from the subject 25. The array 1 can be driven without changing its relative relationship. Incidentally, the moving angles 26 and 27 of the vertically moving plate 12 and the swinging plate 20 are configured to be equal. If the moving table 5 is moved in this state, the element array 1 and the X-ray source 8 move together in relative positions to cross the subject 25 and perform X-ray irradiation.

価値あるものである。Effects of the Invention As described above, according to the present invention, when the subject lies down,
The initial position of the radiation source is far away from the subject, so it is very safe. Furthermore, since the width of the element array is the same as the width of the region to be imaged since the vehicle specimen is scanned in the transverse direction, it is not related to the height of the body, so it can be made compact. In addition, since the X-ray source and semiconductor sensor are connected by a link mechanism, the device can be made smaller without taking up much space, and the distance between the X-ray source and the subject can be changed using the same mechanism. ,
It's valuable.
