PURPOSE:To collect a picture at the same speed as a continuous X-ray irradiating speed, and to improve the quality of a display picture by providing a high- speed shutter which is opened and closed in synchronization with a vertical synchronizing signal of a TV camera, between an output fluorescent surface of an image intensifier and an image pickup tube of the TV camera. CONSTITUTION:An X-ray tube ball 2 is connected to an X-ray generating high- voltage generator 1, X-rays are irradiated to an object 3 from the X-ray tube ball 2 in synchronization with a signal from a TV synchronizing signal generator 8, and transmitting X-rays which have transmitted through the object 3 are detected by an image intensifier 4. An optical image of a fluorescent surface of this intensifier 4 is brought to image pickup by a photoconductive type image pickup tube 6 for a TV camera, and its picture is displayed on a TV monitor 9. An optical lens 5 provided with a high-speed shutter which is opened and closed mechanically in synchronization with a vertical synchronizing signal of a camera from the generator 8 is provided between the fluorescent surface of the intensifier 4 of this X-way TV device and the image pickup tube 6 for the camera. In this way, a picture is collected at the same speed as a continuous X-ray irradiating speed, and flickering of a display picture is prevented. |
