Abstract:
1. An image processing device of a computer tomography system, comprising: an interface which is implemented to receive a first set of X-ray recordings of an object to be examined from first discrete recording angles and to receive a second set of X-ray recordings of the object to be examined from second discrete recording angles; and a calibration data determiner which is implemented to determine calibration data for the computer tomography system on the basis of the first set; wherein the first set is recorded during a first rotation run wherein the computer tomography system and the object to be examined rotate relative to each other and wherein the second set is recorded during at least a further rotation run after the first rotation run, wherein a computer tomography recording is reconstructable on the basis of the calibration data and on the basis of the first and second sets, wherein the first discrete recording angles differ from the second discrete recording angles.
