Abstract
An X-ray system has an X-ray apparatus, an X-ray source and an X-ray receiver on a carrier that is adjustable relative to a subject to be examined for registering 2D projections of a region of the subject from different projection angles with subsequent 3D image reconstruction of the region of the subject, and a position acquisition arrangement having at least one camera allocated to the X-ray apparatus that follows the movements of the X-ray apparatus, and having a position indicator arranged separate from the X-ray apparatus onto which the camera is directed for determining the positions of the X-ray source and the X-ray receiver and for determining the different projection angles of the 2D projections for the 3D image reconstruction. The camera and the position indicator are arranged outside the X-ray beam emanating from the X-ray source.
