摘要

There is described a method using an X-ray imaging unit, which has an arched support for the X-ray source and the X-ray detector. In the method, in a scan carried out by moving the support around an examination object a plurality of X-ray images of an area of interest are recorded using different projection angles, from which a three-dimensional image of the area of interest can be reconstructed. In this case the X-ray focus of the X-ray source is guided on a segment of a circular path of at least 180° around the examination object. In the case of a non-centric location of the area of interest, the support is rotated in such a manner prior to each of the X-ray imaging processes around an axis of rotation passing through the X-ray focus that the central ray of the X-ray beam for the X-ray imaging processes passes through the center of the area of interest.
