Abstract

The present invention is an X-ray device (10, 51, 52) with two rotatable anodes each having a target area for emitting an X-ray beams. The anodes are spaced with an adjustable distance (31) from each other, and the rotational axis of each anode is tiltable with an adjustable tilt angle (32) relative to a detector field plane of a detector (14), detecting each X-ray beam in a common detector field (33).
