ABSTRACT:
A multi-beam x-ray device has a multi-beam x-ray tube in the form of a polygon, wherein the focal spots of the x-ray radiation are arranged along the polygon sides. An x-ray tube control unit controls the x-ray radiation emission such that an x-ray beam is alternately emitted from each polygon side in a specified sequence. Multiple first diaphragms with at least one respective first diaphragm aperture are arranged such that they can move into the beam path of the x-ray tube. A first diaphragm, whose first diaphragm aperture limits the cross section of the x-ray beam emitted from the x-ray tube, is associated with every polygon side. A number of slice images can be generated from different directions without a movement of the x-ray tube.
