ABSTRACT:
A stereoscopic X-ray apparatus is provided in which X-rays are irradiated from the two foci of a stereoscopic X-ray tube to an object to be examined so as to obtain images of the object picked-up in two directions and which permits the object to be stereoscopically displayed based on the two picked-up images. X-ray images having passed the object are picked-up by an image intensifier tube and a TV camera and stored into two frame memories. The two images output from the frame memories are alternately displayed on a display unit. At this time, the positional relation between the object and the X-ray tube and the positional relation between the object and the image intensifier tube set at the picking-up time are compared with those set in the standard state, the display positions of the two images are shifted in the right and left directions by the same distance equal to half the difference therebetween so as to adjust parallax of the two images which corresponds to the stereoscopy, thus making it possible to stereoscopically display the two images with the desired stereoscopy.
