A benchmark of clinical PET using GATE simulation on the computing Grid

The simulation of a real experiment using a GATEmodeled clinical Positron Emission Tomography (PET) scanner, namely PHILIPS Allegro, has been carried out using the Moroccan computing Grid infrastructure, MaGrid. In order to reduce the computing time, the PET simulation tasks are split into several jobs submitted to the Grid to run simultaneously. The splitting technique and merging the outputs are discussed. Results of the simulation are presented and good agreements are observed with experimental data.
