ABSTRACT:
A method is for improving CT image data from a moving examination object, in particular a beating heart. The method includes moving a focus on a circular track about the examination object, wherein scanning data streams, measured in parallel and in a fashion correlated with one another, are collected from a multirow detector. Further, movement data of the examination object are also collected. Angularly complementary data record elements of the same movement phase are retrospectively selected from a number of movement cycles. The data record elements are then reconstructed and reformatted to form incomplete CT images. Subsequently, the incomplete CT images are added up to form complete CT images.
