A method and a computed tomography system are disclosed for producing computed tomograms of an object. A set of detector output data that represent beams over a specific angular range and a scan of a specific subregion of the object, are divided into m>=2 complete partial detector output data records that respectively cover the same complete angular range, but are reduced with their sampling density by 1/m and have mutually independent data records. Intermediate image data records (m records) that represent the identical object region are reconstructed from the m complete partial detector output data records. A correlation analysis is carried out between the m intermediate image data records. Finally, an image data record is produced that consists only of correlated data and includes no uncorrelated data.
