Abstract: This paper shall summarize the research conducted employing the high-purity germanium based small animal imaging system, SmartPET (SMall Animal Reconstructive Tomograph for Positron Emission Tomography). Geant4 simulations of the experimental setup were carried out in order to derive novel analysis procedures and quantify the system limitations. In this paper, we will focus on a gamma ray tracking approach devised to overcome germanium's high Compton scattering cross-section and on imaging challenging and complex phantom geometries. The potential of the developed tools and of the system itself will be discussed. [ABSTRACT FROM AUTHOR]
