Abstract
A rotating x-ray tube has a vacuum housing provided with central shafts at both sides, which are rotatably held in bearings connected to a radiator housing. An anode is rigidly mounted to the vacuum housing, and a cathode arrangement, having an eccentrically disposed cathode, is mounted on one of the shafts. The shaft supporting the cathode arrangement is hollow, and a filament transformer is disposed on the hollow shaft. A further shaft, which is rigidly connected to the cathode arrangement, is conducted through the hollow shaft. The cathode arrangement and/or the interior shaft are rotatably connected to the hollow shaft. The secondary coil of the filament transformer, which is connected to the glow helices of the cathode arrangement, is mounted on the interior shaft.
