Abstract :
The work presented here describes progress in the design and construction of a single-plane PET tomograph having spatial resolution approaching 1 mm. The system consists of a 12 cm diameter ring with 360 LSO detectors viewed by 30 photo-multiplier tubes. Thin (5 mm) crystals and a low energy threshold are used. Crystals are identified using both position arithmetic and energy criteria. To-date the system construction has been completed, system tuning carried out and imaging studies begun
