| 摘要 |
The invention relates to a method for generating tomographical recordings of a partially cyclically moving examination object by a tomography system and a tomography system, comprising the steps of: a spatial scanning of the examination object taking place using at least one detector, which generates detector output data; movement information of the moving subarea of the examination object being recorded during the scanning and being assigned to the detector output data or stored in a manner which correlates to the detector output data; and tomographical image data being reconstructed from the measured detector output data in a number of iteration steps. The invention is characterized in that iteration takes place in at least two iteration stages, with data records being used from the detector output data of different cycle phase regions in at least two iteration stages. |
