Feasibility study of an avalanche photodiode readout for a high resolution PET with nsec time resolution

A feasibility study for a high resolution positron emission tomograph, based on 9.5/spl times/4/spl times/4 mm/sup 3/ LSO crystals viewed by 3 mm diameter avalanche photodiodes, has been carried out. Using a Na/sup 22/ source we determined a spatial resolution of 2.3/spl plusmn/0.1 mm, an energy res...

Zusammenfassung:A feasibility study for a high resolution positron emission tomograph, based on 9.5/spl times/4/spl times/4 mm/sup 3/ LSO crystals viewed by 3 mm diameter avalanche photodiodes, has been carried out. Using a Na/sup 22/ source we determined a spatial resolution of 2.3/spl plusmn/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.< >
