Abstract:
1. A method for generating tomographic image datasets of a measurement object with the aid of a computed tomography system with at least two simultaneously operable sets of detector elements to scan a measurement object from a multiplicity of projection angles, the method comprising: measuring, via at least one first set of integrating detector elements, incident radiation over an entire energy spectrum of the incident radiation in an integrating manner; measuring, via at least one second set of counting detector elements, incident radiation in at least two energy ranges in a resolving manner; correcting, by way of the integrating measurements of the at least one first set of integrating detector elements, the energy-resolving measurements of the at least one second set of counting detector elements relating to rays traversing a measurement object in a spatially identical manner; and reconstructing at least one tomographic image dataset of the measurement object at least from the corrected energy-resolving measurements of the second set of counting detector elements.
