摘要:
A method is disclosed for reconstructing image data of a moving examination object from measured data, the measured data having been acquired during a rotating movement of a radiation source of a computed tomography system around the examination object. In at least one embodiment, first image data are determined from the measured data. Movement information is determined from the first image data by forming the difference between images. Time instants of little movement of the examination object are determined from the movement information, the determined time instants being dependent on the location or site within the examination object. Finally, second image data are reconstructed taking the determined time instants into account. These data can be output as result images.
