Abstract
GRETA, the Gamma-Ray Energy Tracking Array, is an array of highly-segmented HPGe detectors designed to track {\gamma}-rays emitted in beam-physics experiments. Its high detection efficiency and state-of-the-art position resolution make it well-suited for imaging applications. In this paper, we derive the expressions for locating a photon emission point using Compton imaging. We also include expressions for corresponding uncertainty calculations.
