(top) Flood histograms and (bottom) line profiles of the middle row of crystals of the 4 detectors, a detector 1 using 8 × 8 LYSO array of 2.98 × 2.98 × 20 mm3 crystal size, b detector 2 using 8 × 8 LYSO array of 2.98 × 2.98 × 30 mm3 crystal size, c detector 3 using 12 × 12 LYSO array of 1.95 × 1.95 × 20 mm3 crystal size, and d detector 4 using 12 × 12 LYSO array of 1.95 × 1.95 × 30 mm3 crystal size. The flood histograms of detectors 1 and 2 are measured without light guides. The flood histograms of detectors 3 and 4 are measured using light guides with grooves
