摘要：

A feasibility study for a high resolution positron emission tomograph, based on 9.5x4x4 mm(3) LSO crystals viewed by 3 mm diameter avalanche photodiodes, has been carried out. Using a Na-22 source we 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.
