An efficient algorithm for spatial localization of multiple events from detector arrays in FPGA devices

The paper presents an algorithm for identification and spatial localization of multiple events impinging onto arrays of radiation detectors. The algorithm is particularly suited to be implemented into architecture resources of a FPGA digital device that returns very high efficiency in the disentangling and identification process. We discuss design, realization and implementation of the system in the framework of the HICAM project, which deals with the development of a compact and high resolution Anger camera to be used in clinical and research environments.
