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.gtoreq.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.
