Fig. 2 — Schematic showing the error calculation in positioning of a γ-ray in discrete crystal detector and using ROI bins which are: (A) the same size as the crystal and (B) half the crystal size. Point 1 indicates a Compton scatter followed by a photo-electric interaction at point 2 for the entering γ-ray, with the energy-weighted position lying in between as shown in the schematic.
