DEVICE AND METHOD FOR NUCLEAR LOCATING BY ITERATIVE COMPUTING OF BARYCENTER, AND APPLICATION TO GAMMA-CAMERAS

The invention relates to a process for determining the position of an event with respect to a set of N photodetectors, comprising the following after digitization of the signal output by each photodetector:calculate an uncorrected position of the event,determine the distance of each photodetector from the uncorrected position,calculate a corrected value of the contribution of each photodetector as a function of the distance from P0,calculate a new position P1, as a function of the corrected contributions of the photodetectors and their position.Another purpose of the invention is a device for embodiment of the process.
