A computed tomography system includes a radiation sensitive detector element (100) which provides outputs (DL, DH) indicative of the radiation detected in at least first and second energies or energy ranges. Energy resolving photon counters (26) further classify the detector signals according to their respective energies. Correctors (24) correct the classified signals, and a combiner (30) combines the signals according to a combination function to generate outputs (EL, EH) indicative of radiation detected in at least first and second energies or energy ranges.
