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 on a gantry, the two detectors being offset at an angle to each other, the two detectors including an integrating detector to integrationally measure incident radiation over an 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 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 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 reconstructed first tomographic image dataset with the reconstructed second material-selective tomographic image dataset.
