Abstract
An X-ray diagnostic apparatus has a computed tomography device including a first X-ray tube, which is fastened to a gantry ring (,) and which emits a fan-shaped effective beam, and an opposed radiation receiver, which is formed by a row of individual detectors, each of which forms an electrical signal corresponding to the received radiation intensity. A second X-ray tube is additionally fastened to the gantry ring at a right angle to the first X-ray tube, opposite which, at the gantry ring, a matrix-like X-ray detector is arranged. The second X-ray tube is activated in specified positions in pulsed fashion, such as at the uppermost rotational point. X-ray shadowgraphs thus can be produced simultaneously with CT images and without a need for repositioning any of the apparatus components.
