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])
