Users' Workshop

Oral presentation Users Workshop

We developed a simulation in Geant4 to compare the attenuation properties and the bremsstrahlung radiation yield of different types of plastic materials employed as shield of beta radioactive sources. Code validation results against Sandia and NIST data are presented. We discuss the influence of cuts in range, step limits and multiple scattering step limitations, for the three physics packages...

51. USE OF GEANT4 CODE FOR VALIDATION OF RADIOBIOLOGICAL PARAMETERS OBTAINED AFTER PROTON AND CARBON IRRADIATIONS OF MELANOMA CELLS

Oral presentation Users Workshop

Series of numerical simulations with the GEANT4 code were carried out to verify and better interpret radiobiological parameters and biological effects obtained after irradiation of HTB140 human melanoma cells. Irradiations were performed at INFN-LNS with the 62 MeV proton beams at the full energy Bragg peak as well as along the spread out Bragg peak (SOBP) and its distal fall-off part. HTB140...

Background: The importance of Monte Carlo (MC) simulations in the field of advanced radiation therapy increases with the necessity to investigate the effect of detectors, monitoring systems and ripple filters at the design phase. In this work we present our investigations using MC simulations of the effects of each of the elements in a beam delivery line of a particle therapy...

Users' Workshop

Oral presentation Users Workshop

We have been developing a Monte Carlo simulation software to be applied in clinical usage. To apply a Monte Carlo simulation in clinical support, the reproducibility of real irradiation is prerequisite. From modeling the therapeutic nozzle to mimicking treatment scheme, we have successfully modeled our beam delivery system which is using rotation modulation wheels to generate a spread-out...

27. New physics processes dedicated to nanometric scale track structure in the Geant4 toolkit

Dr Ziad Francis (IRSN FRANCE)

Users' Workshop

Oral presentation Users Workshop

Track structure simulation using the Monte-Carlo method has become increasingly important not only on the macroscopic scale but also on the nanometric and the molecular simulation level. Many studies (mostly done by Nikjoo et al., and Goodhead et al.) showed that damage clustering in cell nucleus is related to the energy deposits distribution inside the cell. However, experimentally it is...

64. INVESTIGATING THE ACCURACY OF HADRONIC MODELS FOR CARBON ION THERAPY

Users' Workshop

Oral presentation Users Workshop

Introduction: An accurate prediction of radiation fields resulting from therapeutic carbon ions in the patient is needed in order to evaluate correctly their biological effectiveness. Materials and Methods: Hadronic models of the Monte Carlo transport codes: Geant4 and Fluka, are benchmarked for regimes relevant for therapeutic carbon ions. The ability of the Monte Carlo codes to...
