1. A method for reconstructing image data of a moving examination object from measured data, the measured data being acquired during a rotating movement of a radiation source of a computed tomography system around the examination object, the method comprising:

  • determining first image data from the measured data;

    determining movement information by forming a difference between images from the determined first image data;

    determining time instants of relatively little movement of the examination object from the determined movement information, the determined time instants being dependent on a site within the examination object; and

    reconstructing second image data taking into account the determined time instants.
