DEVICE AND PROCESS FOR NUCLEAR LOCATION BY WEIGHTED BARYCENTER CALCULATION USING PARALLEL-OPERATING DETECTORS, AND APPLICATION TO GAMMA CAMERAS

摘要

The invention relates to a process and a device for determining the position P0, with respect to a series of N photodectectors of an event inducing a signal in the N photodetectors. The process comprises the following steps: a) digitization of the signal delivered by each photodetector; calculation of the energy of the signal delivered by each photodetector; b) calculation, for each column, of the column's contribution to the total energy, the column's contribution to the barycenter, in X, of the event, and the column's contribution to the barycenter, in Y, of the event; c) determination of the total energy induced by the event, and of the barycentric coordinates of the event with respect to the N photodetectors.
