ABSTRACT:
An X-ray diagnosis apparatus comprises an X-ray source for obtaining images of an object by means of cine-fluorographic image pickup and TV image pickup, first and second X-ray image pickup systems comprising image intensifiers, TV cameras, cine-fluorographic movie cameras, etc., a single image processing system for subjecting TV images obtained by the first and second X-ray image pickup systems to image processing, a buffer system, disposed between one of the X-ray image pickup systems and the image processing system, for buffering the image transmitted from this one of the X-ray image pickup systems to the image processing system, and a display system for displaying the image processed by the image processing system. In this apparatus, images from the first and second X-ray image pickup systems can be sequentially delivered to the single image processing system in a time-divisional manner.
