Abstract

Two experimental PET camera modules were constructed using (1) two 5 × 5 × 2.5 cm3 detector stacks made of parallel 0.5 and 1.0 mm diameter scintillating fibers and (2) two 5 × 5 × 5 cm3 detector stacks made of alternating x and y layers of 0.5 and 1.0 mm diameter scintillating fibers. Each stack was viewed by Hamamatsu R2486 position sensitive photomultipliers. The time resolution of the coincidence system was 10 nsec. The spatial resolution and efficiency of the PET modules was tested using an approximately 1 μci 0.5 mm diameter Na-22 source. The best results were achieved with the 1.0 mm parallel fiber stacks: 2.0 mm spatial resolution (FWHM) and 2.3 % efficiency. Possibilities to improve the characteristics of this arrangement and, particularly, the alternating x and y layer sucks are discussed.
