摘要:
A method is disclosed for increasing the quality of computer tomographic recording series, to a computation unit and to an X-ray CT system. An embodiment of the method includes scanning a subject over a period of time which makes it possible to record at least two temporally offset projection data sets of the same recording region transforming the projection data sets into transformation data sets for at least two spatial frequency ranges calculating temporal compensation values of the transformation data sets for some of the spatial frequency ranges and replacing the compensated values of the transformation data sets with the calculated compensation values in new transformation data sets, projection data of congruent rays always being compared transforming the new transformation data sets back into new projection data sets reconstructing image data sets on the basis of the new projection data sets and representing the image data sets.
