Abstract
An X-ray exposure system has a mobile X-ray apparatus with an X-ray source and an X-ray receiver that are adjustable relative to a subject for registering successive 2D projections of the subject from different projection directions, an arrangement disposed outside the beam path of the X-ray beam emanating from the X-ray source for directly determining the projection geometries of the X-ray source and of the X-ray receiver at the points in time of the individual 2D projections, and a computer supplied with signals from the arrangement for the direct determination of the projection geometries, which reconstructs 3D images of the subject from the 2D projections.
