Verfahren zur Rekonstruktion eines Prüfobjekts bei einem Röntgen-CT-Verfahren in einer Röntgen-CT-Anlage

The invention relates to a method for reconstructing a test object in an x-ray CT method in an x-ray CT system, which has an x-ray source having a focus, an x-ray detector, and a manipulator, wherein the manipulator can move a test object in the intermediate space between the focus and the x-ray detector, wherein markers, the position of which in relation to each other is known, consist of materials transparent to x-radiation and are arranged in a stationary manner in relation to the test object while the method is carried out, wherein a specifiable trajectory is traveled, during which recordings of the test object are taken under different projection geometries, wherein the projection geometry of each individual recording is calculated from the positions of the markers while taking into consideration the position relative to each other in the recording, and then a CT reconstruction of the test object is performed by means of a suitable algorithm on the basis of the association of the individual recordings with the respective projection geometries.
