PURPOSE:To enable optical adjustment of an indepth looking and stereoscopic looking in stereoscopic observation by obtaining an X-ray image continuously based on a pulse X ray in a specified direction of rotation of a subject continuously to display image pairs selected. CONSTITUTION:X-ray tube 1 irradiates X rays in pulse repeatedly to expose and the X rays transmitted through a subject 2 are converted into light informa tion with I.I.3 to be taken with a TV camera 4. Then, a video signal is converted into digital from analog with an A/D converter 5 to be recorded with an image memory 6 (61, 62, 63-6n). Among the images recorded, two images having a fixed frame interval, for example, those recorded in the image memo ries 61 and 62 are displayed on TV monitors 9a and 9b through independent D/A converters 8a and 8b. The two images have a fixed frame interval to be shifted in an angle of photography to a subject 2 when taken. Thus, there is a parallax generated between images entering two eyes of an observer, there by allowing the observer to obtain a stereoscopic looking.
