Abstract

A camera consisting of two barium fluoride scintillation crystals sandwiched between three low-pressure photosensitive wire chambers is described. For 511-keV annihilation radiation, the detection efficiency is 42% and the position resolution is 5 mm (full width at half maximum) with a time resolution of 4 ns. The camera is insensitive to low-energy scattered radiation. The merits of the detector for application in a PET system are discussed. The advantages of such a system over a conventional ring system would be its high coincidence efficiency, small deadtime, and insensitivity to low-energy scattered radiation
