Patent ID: 8588493

Claim:
A method for reconstructing image data of a moving examination object from measurement data, wherein the measurement data has been captured in a course of a relative rotational movement between a radiation source of a computed tomography system and the examination object, the method comprising: calculating a first image of the examination object from a complete measurement data record of the measurement data for an image reconstruction and a second image of the examination object from an incomplete measurement data record of the measurement data for an image reconstruction; frequency splitting the first and second images, respectively, in at least one low-frequency component and one higher-frequency component; and supplementing image data of the second image, in the low-frequency component, with image data of the low-frequency component of the first image, wherein in a further processing the supplemented second image is improved using the first image such that errors due to the incompleteness of the measurement data record of the second image are reduced.
