Optical Simulation of a DOI Detector with Stack of Planer Scintillator

| Depth of interaction (DOI) detector is essential to achieve both high resolution and high sensitivity. Previously, our group proposed four layer DOI detector which was composed with small segmented crystals and inserted reflectors. To reduce assembling steps, we propose new detector which is inserted laser processed boundaries (LPBs) into a monolithic crystal instead of gluing small crystal segments. The four layer DOI detector shows high discrimination accuracy at center of detector. On the other hand, it is difficult to discriminate clusters of detector edge when Anger logic is used for position estimation. We propose cluster discrimination method using SVC. |
