Patent abstract
Spectral CT systems require cheap detectors with high energy resolution. According to an aspect of the present invention, a computer tomography apparatus comprises a detector element which is segmented into a plurality of sub-pixels. Each sub-pixel has at least two thresholds and counting channels, wherein the second threshold for each sub-pixel varies over the nominal detector element. This may provide for an improved energy-resolved photon counting.
