Abstract
A method for operating an imaging X-ray device, and the imaging X-ray device, are disclosed for acquisition of projection images. In an embodiment, X-rays are emitted from at least one X-ray source and, after passing through a tunnel-shaped examination region, acquired by at least one X-ray detector. At least the X-ray source is moved on a circular path or a circular arc section about a center of rotation in a plane of rotation. Herein, a patient couch is moved in a feed direction extending perpendicularly to the plane of rotation. According to at least one embodiment of the invention, a pitch factor is specified characterizing a feed of the patient couch in each unit of time as a function of an at least approximately ascertained position and/or extension of a region to be mapped in the plane of rotation with respect to the center of rotation.
