专利汇可以提供X-ray television device专利检索,专利查询,专利分析的服务。并且PURPOSE: To produce an after-image effective for the reduction of X-ray quantum noise by lowering the target impressing electric field strength of an image pickup tube in which a block-type photo conductive layer is provide.
CONSTITUTION: X-rays generated at an X-ray tube 1 are made incident on an X-ray image intensifier 3 passing through a subject to be tested 2. And they are converted to rays of light and are image-picked up at a television camera 7 through a tandem lens 4 and displayed at a monitor 8. At such a time, the target impressing electric field strength of the image pickup tube is set below 1.24 × 10
7 v/m and at the same time, a movable optical diaphragm 5 and a light image intensifier 6 are adjusted. By using such a device, it is possible to reduce the X-ray quantum noise and to use the image pickup tube with high resolution power and low after-image.
