Experimental Study of Using a 3-D Position Sensitive CdZnTe Detector for
Proton Beam Range Verification
Abstract
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.
