  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 use
simulated imaging data to illustrate how imaging can be applied to nuclear
lifetime measurments. This approach can offer multiple benefits over
traditional lifetime techniques such as RDM.
