ABSTRACT:
A multi-beam x-ray device has a multi-beam x-ray tube with an interior in the form of a circle. Focal spots of the x-ray radiation are arranged along the circle. An x-ray tube control unit controls the x-ray radiation emission such that an x-ray beam is emitted from each segment of the circle in specified sequence. The circle is divided up into at least two segments, and multiple diaphragms, each with at least one diaphragm aperture therein, one mounted to rotate around the center point of the circular path 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 each segment of the circular path. A number of slice images can be acquired without a movement of the x-ray tube.
