摘要

The present invention relates to a process for the differentiation and representation from moving and non-moving heart regions of a patient in the x-ray - ct, comprising the following process steps:- Carrying out a circle - or spiral scanning of a patient (7) in the region of its heart (16) with the aid of an x-ray - cts (1) with a detector (3, 5) with a plurality of detector elements and storing at least one sino gram of a plurality of projection data from circumferential projection directions,- Reconstruction of at least a tomographic representation of the heart (16) from the at least one sinogram and display of the at least one reconstructed representation of the heart (16).According to the invention, the projection data is subjected to a fourier transformation, with respect to a predetermined frequency is filtered retransformed, reconstructs, and in combination with the tomographic representation of the heart (16) is output.
