Abstract
A method is disclosed for producing a noise-reduced CT image data record by frequency band breakdown, a computer system for carrying out the method, and a CT system () with such a computer system. In an embodiment of the method, several linear-combined mixed image data records are produced from several simultaneously-recorded energy spectrum-specific CT image data records (X); a frequency band breakdown of the mixed image data records (M) takes place into a first lowest frequency band (F) and several higher frequency bands; and a result image data record is calculated, wherein each mixed image data record (M) is multiplied with precisely one filter and with a location-dependent function (g(r)) and is thereby totaled, and wherein g(r)=1.
