  2. Outline • Brief summary of the Geant4 IMRT application • Updates: • Parallelization • Statistical analysis of the results

  3. primary collimator jaws flattening filter phantom Geant4 IMRT application • Accurate description of the beam line both in terms of: • Beam line geometry • Primary particles • Low Energy Physics to model the interactions of particles • Result of the simulation: • Percent Depth Dose (PDD), • The lateral profiles at the following depths in the phantom: 15 mm, 50 mm, 100 mm and 200 mm, • Isodose curves in specific planes

  4. Activities in progress • Parallelization • Comparison of dose distribution in the phantom with respect to experimental measurements: statistical analysis • See Barbara’s talk

  5. Parallelization • Parallelization of the Geant4 IMRT application • Run on a dedicate cluster • Run on the GRID • Use of DIANE • Activity born from the collaboration of: S. Guatelli, A. Mantero, J. Moscicki, M.G. Pia
