This manuscript discusses the use of a large volume array CZT detector for experimental prompt gamma-ray imaging. Namely, the 718 keV and the 4.44 MeV photopeaks produced from proton-carbon interactions are imaged using maximum likelihood expectation maximization (MLEM). Various proton beam irradiations are used to characterize the feasibility of using both photopeaks for beam range verification.
