Simulation Monte Carlo des dépôts de doses en radiothérapie curiethérapie et déploiement sur grille de calcul

Abstract

RÉSUMÉ ABSTRACT Monte Carlo simulation of doses deposits for radiotherapy -brachytherapy and deployment on the computing grid.Monte Carlo is the algorithm that most closely models the actual physics of the energy deposition process. Thus it would be very interesting to use this method in the cancer treatment planning by radiation. Indeed, existing treatment planning systems (TPS) are limited in the accuracy of dose calculations for certain specific cases. In this approach, we are interested in the validation GATE Monte Carlo toolkit for dosimetric applications in medical physics (Radiotherapy and Brachytherapy). However, the use of Monte Carlo method for complex geometries or images with a large resolution requires a large computing time. Indeed, a precise result can be obtained only by generating a large number of events. We thus study the performances of the computing grid to reduce computing time by deploying GATE simulations on the grid architecture developed within the framework of EGEE European project.

Assessment of Computed Tomography Dose Index (CTDI) During CT Pelvimetry Using Monte Carlo Simulation

“…Among these codes, we can mention MCNP, MCNPX and GEANT4 [16][17][18]. In this work, GATE code based on the use of GEANT4 libraries was used [19]. These libraries offer the user the ability to run validated physical models, build complex geometries, generate and track particles, visualize volumes and trajectories of particles, as well as other specific modules.…”
