A method for determining the position of a scintillation event in a radiation particle detector with multiple scintillator element locations which are configured to emit a burst of photons responsive to a radiation particle being absorbed at the scintillator element location and with a plurality of photosensors ( 5.1, 5.2, 5.3, 5.4 ) optically coupled to said scintillator element locations, comprising the steps of determining, for each of the photosensors ( 5.1, 5.2, 5.3, 5.4 ), a triggering probability indicative of the probability of said photosensor ( 5.1, 5.2, 5.3, 5.4 ) measuring a number of photons that exceeds a predetermined triggering threshold; measuring a photon distribution with the photosensors ( 5.1, 5.2, 5.3, 5.4 ) indicative of the number of photons incident on the individual photosensors ( 5.1, 5.2, 5.3, 5.4 ); calculating, for each of the scintillator element locations, a likelihood that a scintillation event with a predetermined energy value took place in said scintillator element location based on the measured photon distribution and the triggering probability of each of the photosensors ( 5.1, 5.2, 5.3, 5.4 ); and identifying the scintillator element location having the maximum likelihood. |
