Use of Position Sensitive Detectors in Positron Imaging

The use of Anger-type bar cameras for positron imaging results in a totally stationary system. In addition, the design is cost effective since the Anger principle will provide many resolution elements using only a few crystals and photomultipliers. Pulse shortening techniques are used to solve countrate problems associated with Anger-type detectors. When compared to an array of BGO detectors, a bar camera with equal sensitivity has superior spatial resolution.
