Abstract
An x-ray apparatus includes an x-ray emitter having an x-ray tube, a rotary anode disposed in the x-ray tube, and a drive for the rotary anode. The drive includes a reluctance motor having a stator disposed outside the x-ray tube and a rotor disposed inside the x-ray tube. The rotor is mechanically connected to the rotary anode.
Claims19
An x-ray apparatus comprising:
- an x-ray emitter comprising:
- an x-ray tube configured to generate an electron beam;
- a rotary anode disposed in the x-ray tube, wherein the x-ray tube is configured to generate the electron beam, such that the electron beam intersects the rotary anode;
- and
- a drive for the rotary anode,
- wherein the drive comprises a reluctance motor having a stator disposed outside the x-ray tube, and a rotor disposed inside the x-ray tube, the rotor being mechanically connected to the rotary anode;
- and
- wherein an axis of rotation of the rotary anode is oblique to a direction of the electron beam.
