摘要

For as low as possible a radiation exposure for as large a 3 - d - x-ray exposure, a process for the reception of an object to be examined around a common axis of rotation (1) rotatable x-ray imaging system, consisting of an x-ray source (q) and an x-ray detector (d), are provided, and, in the case of a first rotation in the case of a plurality of first angular positions of the x-ray source (q) and the x-ray detector (d) about the axis of rotation (a) first x-ray images are absorbed, with the x-ray detector in a first direction is arranged offset, so that the mean perpendicular of the x-ray source on to the x-ray detector with a the x-ray source (q) and passing through the axis of rotation (a) plane containing a first angle k ≠ 0, and in the case of a second rotation in the case of a plurality of second angular positions of the x-ray source (q) and flat x-ray detector (d) about the axis of rotation (a) second x-ray images are absorbed, with the x-ray detector in a second direction is arranged offset, so that the mean perpendicular of (m) of the x-ray source on to the x-ray detector with a the x-ray source (q) and passing through the axis of rotation (a) containing a plane (e) a second angle m ≠ 0, the second angle with respect to the plane on the opposite side to the first angle k is located, wherein the first and second rotation about the axis of rotation between their starting points and their end points in each case at most, ..
