I want to simulate PET data using simulation monte carlo via gates, but I can't specify geometry of detectors etc. I don't have this background skills. Could anyone send me two scripts about simulation PET data acquisition using GATE, one without considering any scattering or any kind of noises and data have to be stored into sinogram format? The other script concern data simulation in case considering scattering for example stored into sinogram. There is no condition about other parameters.
