Fig. 2From: Monte Carlo modelling of a compact CZT-based gamma camera with application to 177Lu imagingA Volume rendering of a CIE map (\(\eta _k\)). B Cross section of a CIE map with photon interaction positions from SIMIND overlaid as black points. The collimator septa (MEGP) are indicated at the bottom, and the decreased probability for interactions behind them can be noted. Dotted lines indicate the lateral centres of the anode gapsBack to article page
