Abstract
A method is disclosed for reducing step artifacts in the forward increment direction of a cardio CT representation. In at least one embodiment, volume recordings or section images of first and second sub-volumes of a heart volume, which lie adjacent to one another in the forward increment direction and partially overlap in an overlap region, are recorded by a computer tomography system. Each sub-volume's detector data is used for the reconstruction coming from different heart cycles. Finally, a displacement vector relative to a second sub-volume is determined at least for a selected point of the overlap region of a first sub-volume and the second sub-volume is subjected at least partially to a spatial transformation according to the at least one displacement vector.
