ABSTRACT:
A stereoscopic x-ray tube has an evacuated housing with a motor-driven anode dish therein, as well as at least two cathodes. The cathodes are disposed for directing electrons onto two respective foci within at least one track of the anode dish. Each of the foci generates a beam of useful x-rays, the two beams alternating. The anode dish is divided into at least one pair of segments of identical size, each segment emitting x-rays of a different intensity, so that only one segment in each pair can emit useful x-rays. The cathodes are disposed such that their respective foci are spaced at an uneven multiple of the length of the track within a segment.
