GEANT4, PENELOPE and EGSnrc Monte Carlo Codes: Do you need to use Monte Carlo codes to solve your problem…? Can you use a faster PC or “clever” math's, physics or numerical tricks to solve your problem; How accurate is your Monte Carlo physics …? Possible issues are: 1.Multiple scattering 2.Bremsstrahlung 3.Photo-electric/Compton/Pair-Production/Rayleigh/Stopping Powers etc… How fast is you Monte Carlo code….? Can it run on 1 PC or does it need a large cluster … keeping in mind that clinical plans must not take more than 1 hour to generate; How versatile is your MC code… can it do photons, electrons, protons, carbon ions, etc… ?

Abstract In this work, the condensed history algorithm in GEANT4 (version p01) is examined. Simulations of an ionization chamber composed of water for 1.25 MeV incident photon beams under Fano conditions, and evaluated the consistency of the cavity response for several combinations of electron transport parameters. GEANT4 permits electrons to reach geometric boundaries in large steps, and underestimates lateral displacement near interfaces. Step size artifacts due to distortions in electron fluence and angular distributions reduce the cavity dose by up to 39%. Accurate cavity response can be achieved using severe user-imposed step size restrictions. [They] suggest that improvements in the electron transport algorithm in GEANT4 should address the handling of boundary crossing.
