Abstract

A feasibility study for a high resolution positron emission tomograph, based on 9.5×4×4 mm³ LSO crystals viewed by 3 mm diameter avalanche photodiodes, has been carried out. Using a Na²² source the authors determined a spatial resolution of 2.3±0.1 mm, an energy resolution around 15% and a time resolution of 2.6 nsec. Possible configurations for larger scale tests and a tomograph are given
