PhoSim is an optical ray tracing Monte-Carlo simulator capable of reproducing the physical processes taking place in a tissue environment when illuminated by Near-Infrared radiation. From a macroscopic point of view this can be accomplished by the proper manipulation of the Henyey-Greenstein phase parameter g, which represents a simple and analytical solution for the fast generation of a random scattering...
The current work focuses on the Time-Resolved Optical Tomographic (TROT) modality and mainly studies the scattering process that takes place in a diffusing medium like tissue when Near-Infrared radiation propagates through it. Additionally, it handles the time filtering which is necessary to be performed on the detected photons in order to gain the anatomical information of an area under investigation...
Due to the nature of the Compton Camera operation, the detection efficiency for distributed γ-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...
