Abstract:
1. A method for X-ray image recording using an X-ray imaging unit, comprising: providing the X-ray unit, wherein the X-ray unit has an X-ray source and an X-ray detector opposite the X-ray source on an arched support, wherein an X-ray beam emitted from an X-ray focus of the X-ray source strikes the X-ray detector; recording a plurality of X-ray images during a scan of an area of interest of an examination object using different projection angles, wherein during the scan the support is moved around the examination object, wherein the examination object is positioned between the X-ray source and the X-ray detector, and wherein during the scan the X-ray focus is guided on a segment of a circular path of at least 180° around the examination object; reconstructing a three-dimensional image of the area of interest from the plurality of X-ray images; and rotating the support prior to recording each of the plurality of X-ray images around an axis of rotation passing through the X-ray focus, if the area of interest is in a non-centric position, wherein the central point of the circular path is situated non-centrically in the area of interest, and wherein the support is rotated so that a central ray of the X-ray beam for recording the X-ray images passes through the center of the area of interest.
