ABSTRACT:
In a computed tomography apparatus having a gantry, on which a rotating anode x-ray tube and a radiation detector are disposed, the gantry being rotatable around a system axis and being tiltable relative to an axis extending perpendicularly to the system axis, the direction of rotation of the gantry is opposite the direction of rotation of the rotating anode in the x-ray tube. Gyroscopic forces acting on the bearing of the rotating anode are thereby at least partially cancelled, significantly reducing mechanical stress on the anode bearing.
