This paper reports on the increased scatter fraction seen in positron volume imaging when compared with conventional slice positron emission tomography which has created a need for better characterization and correction of scattered gamma rays for positron imaging. An analytical simulation of single scattered gamma rays and an extension to estimate multiple scattered rays were verified using Monte Carlo simulation. The Monte Carlo simulation was itself verified using measured tomography data. The analytical simulation was used to study some cases of interest for scatter correction.
