Abstract
The techniques described herein provide for correcting for pulse pile-up and/or charge sharing in a radiation scanner (). It finds particular application with the use of a pixilated radiation detector () (e.g., a photon counting detector). A circuit (), comprising a plurality of comparators (), is configured to determine the energy spectrum of a pulse produced from a photon strike. If the energy spectrum is greater than the energy range for a pulse produced by a single photon strike given an input spectrum and/or if pulses produced from adjacent pixels have temporal coincidence, pulse pile-up and/or charge sharing may be identified and a correction mechanism/correction factors may be applied to determine an actual number of photons that struck the detector ().
