I am trying to alter the TestEm1 example to allow for the G4GeneralParticleSource to be used to allow me to simulate a positron point source being emitted. The reason for this is because I want to model these positrons from specific isotopes, specifically those important to PET. For example, I have a volume of tissue and I need a F-18 positron point source to be emitted and have its range be tracked and recorded. I then will apply different strengths of magnetic fields to see the alterations in the range of the positrons as they travel through the tissue medium. I had originally just used the example TestEm1 to do this, but this was modeling monoentergetic positrons and I am in need of modeling polyentergetic positrons, thus the F-18 source method would work. Any assistance regarding altering the TestEm1 code to allow for the GPS to be used would be much appreciated. Or maybe I am heading down the wrong track...any advice would be much appreciated. Thanks in anticipation, Matthew Middione
