摘要: A method and a computed tomography system are disclosed for generating tomographic image datasets of measurement object with multiple simultaneously operable sets detector elements. In at least one embodiment, first set measures incident radiation over the entire energy spectrum in an integrating manner second two ranges resolving manner, wherein furthermore by way measurements, energy-resolving measurements relating each case to rays traversing spatially identical corrected dataset is reconstructed from measurements.
