摘要：
Due to the nature of the Compton Camera operation, the detection efficiency for distributed gamma-sources is strongly affected by the angular acceptance and the interaction probability of the photon for a given tracer energy. In order to overcome imposed artifacts and other deformation effects in the final image, an optimization method for the reconstruction procedure is proposed. It is based on a GEANT4/GATE simulation study and the parameterization of the recorded planar distortion of homogeneous plane sources placed at different distances inside the cameras field of view. The efficiency of this method is presented for a variety of 3D reconstructed phantoms and the achieved improvement in spatial resolution is discussed.
