Abstract:
A method, disclosure relates to for improving detection of true coincidence events and differentiating them from events detected from scattered and random gamma photons, comprises receiving electromagnetic radiation at a plurality of photo detectors that was generated by a scintillating crystal impacted by a gamma photon, and processing data received at a subset of the plurality of photo detectors that are closer to a scintillating crystal, thereby improving a timing coincidence window for detecting a coincidence event.
