The SmartPET is a detection system comprising two monolithic HPGe double sided strip detectors, offering both spatial as well as excellent spectral resolution. While the SmartPET was originally intended for observation of positron emission sources, the system is also an excellent test-bed for the investigation of single-photon emission imaging when configured as a Compton camera. The concept of the Compton camera is described in terms of medical emission imaging, and experimental results of the SmartPET in Compton camera configuration are presented. Processing based on Compton kinematics is useful not only in single-photon imaging, but also in the processing of PET data by providing a means of data discrimination. The discrimination process is presented using data from simulations of SmartPET-like detectors.
