Abstract
For accurate position calculation of scintillation events in a gamma camera, photodetector signals are processed based on small groups of photodetectors surrounding the scintillations. Relative position correction and energy correction is carried out based on rough position values relative to the group of photodetectors, taking into consideration the number of the center photodetector and the sum of all photodetector signals in the group.
