A Monte Carlo simulation of gamma-ray transport within a single-slice positron emission tomography (PET) ring camera has been developed. Included in the simulation are the radioactive source distribution, collimators, and detectors with inter-crystal septa. The modelling code has been used to study the effect of the septa and BGO detector width on system(More)
A Monte Carlo simulation of the gamma ray transport within a single-slice positron emission tomograph has been generated to study the effects of system parameters on performance. Included in the simulation are the radioactive source distribution, collimators, and detectors with intercrystal septa. Data are first presented to show the coincidence and singles(More)
Although the spatial resolution in positron emission tomography is improved by reducing the crystal width, the resolution becomes increasingly non-uniform towards the edges of the field of view. This is mainly due to penetration of the gamma rays through one or more crystals before detection and the inability of current systems to resolve the depth of(More)
