Abstract

A method is for producing CT images of a periodically moving object to be examined, in particular a method for cardio volume reconstruction for multi-row CT units in spiral mode. A multi-row CT unit designed is further designed therefore. A small partial revolution segments along a revolution spiral is used to calculate in each case per partial revolution segment a plurality of segment images that are converted in a second step to partial images in the target image plane (for example axial plane) and are assembled with the correct phase to form complete images.
