Process for the localization of multiple scintillation events in a gamma camera

摘要

In a method for the localization of scintillation events in a gamma camera with a number of photomultipliers the output signals of the photomultipliers, in dependence on a release signal, are subjected to a pattern recognition process. In the pattern recognition process the output signals are compared with comparative signal sets which each comprise the expected values of output signals from photomultipliers which would be generated by several comparative scintillation events with at respective origins at known locations. The locations of the multiple scintillation events are then registered as the origins that belong to a comparative signal set which presents the greatest similarity value to the output signals in question.
