Method for producing tomographic image data sets of patient, involves correcting energy resolution measurement with respect to measurement object radiations, and reconstructing data set from corrected measurement
The method involves performing integral measurement of incident radiation by a set of honey comb-shaped detector elements of a computed tomography (CT) system (1), over an entire energy spectrum of the incident radiation. Resolution of the incident radiation is measured in two energy ranges by a set of counter detector elements of the system. The resolution measurement is corrected with respect to spatially and directly extending measurement object radiations, by the integral measurement. A tomographic image data set of a patient (7) is reconstructed from the corrected measurement. Independent claims are also included for the following: (1) a computer system for evaluating measurement results of detector element (2) a CT system.
