Detector Designs used in PET One-to-one coupling: • Single crystals glued to individual photo-detector • Spatial resolution limited by discrete crystal size Block detector design: • Rectangular scintillator

block sectioned by partial saw cuts of different depth into discrete elements • Usually 4 attached PMTs • Anger positioning

Standard block detector design scheme (from [2])
