Claim:
1. An X-ray tube for monoscopic and stereoscopic viewing, the X-ray tube comprising: a cathode arrangement; an anode; and a deflection device, wherein: the cathode arrangement and the anode generate an electron beam from the cathode arrangement and direct the electron beam towards a target area of the anode to generate X-ray radiation through electrons of the electron beam impinging on the target area; the deflection device controls the electron beam such that the electrons hit the anode at different focal spot positions; the deflection device provides gradual deflection for a stepless transition between the monoscopic viewing and the stereoscopic viewing; in the monoscopic viewing, the X-ray radiation is generated from a single focal spot position, in the stereoscopic viewing, the X-ray radiation is generated from two focal spot positions spaced apart from each other in a first stereo-direction transverse to a viewing direction, and the deflection device provides gradual deflection for a stereo focal spot position in a second stereo-direction, which is transverse to the first stereo-direction and transverse to the viewing direction.
