Abstract :
A BaF/sub 2/-TMAE detector has been developed for use in positron emission tomography (PET). The detector achieves an efficiency of 23.5%, a time resolution of 3.5 ns FWHM, and a spatial resolution of 6.0 mm FWHM with no change in the normal operating parameters. The only deterioration observed in a typical working day is a small increase in the FWTM of the time resolution. This paper describes how this level of performance was achieved and also how these results have been used as the basis for the design of a large area positron camera.<>
