Full dynamic brain simulation using GATE in a high-performance computer

Dynamic PET brain studies are common in research and are becoming common in clinical applications. Simulation of dynamic PET is an important step to validate techniques and methods. This study compares the CPU and GPU version of a GATE simulation running on a high-performance computing system. We simulated the Siemens 3T MR-BrainPET with dynamic brain activity. The results show close agreement in the number of coincidence events, including phantom scatter, which we made available in the output of GPU simulation through code changes. The code will be made available to the GATE community and the simulation data is available to the interested researchers.
