Claim One:
1. A method for generating a tomographic result image dataset of an at least cyclically moving part of a measurement object, with the aid of a dual-source CT system including two detectors disposed on a gantry offset at an angle to each other, the two detectors including an integrating detector to integrationally measure incident radiation over the entire energy spectrum of the incident radiation, and a counting detector to simultaneously measure incident radiation in at least two energy ranges in a resolving manner, the method comprising: using the projection data of the integrating and the counting detector from a quarter rotation of the gantry jointly, for reconstruction of a first tomographic image dataset; using the energy-resolved projection data of the counting detector from at least one half rotation of the gantry for reconstruction of at least one second material-selective tomographic image dataset; and forming at least one tomographic result image dataset by overlaying the first tomographic image dataset with the material selection of the second image dataset.
