A method is disclosed for generating computed tomography image data records of a patient in a heart CT scan during a perfusion control by applying contrast agent. In at least one embodiment, a plurality of temporally consecutive CT data records are recorded as an exposure series with a CT system and if necessary are reconstructed. These CT data records are improved for better visualization of the perfusion by way of electronic filtering and post-processing, with all projection and/or image data determined during a CT scan being used, however with the aid of frequency filtering only the data of a projection or of a reconstructed image for generating a final representation being used which does not fall within a predetermined local frequency range of a heart movement.
