Abstract

The rotating anode x-ray tube comprises an anode, whose focal track has the shape of a saddle trajectory. A proper anode angle to enable a high power line focus is always realised along the focal path on the anode. The x-ray tube is for CT scanners and enables a movement of the focal spot along the patient axis during gantry rotation. In this way, cone beam artefacts due to the reconstruction may be avoided.
