A GPU implementation of EGSnrc's Monte Carlo photon transport for imaging applications [PDF]
Physics in Medicine and Biology, 2011 EGSnrc is a well-known Monte Carlo simulation package for coupled electron-photon transport that is widely used in medical physics application. This paper proposes a parallel implementation of the photon transport mechanism of EGSnrc for graphics processing units (GPUs) using NVIDIA's Compute Unified Device Architecture (CUDA).

Validação dosímetrica de trabéculas ósseas sintéticas geradas por método Monte Carlo paramétrico
Brazilian Journal of Radiation Sciences, 2018 Um dos maiores desafios da dosimetria numérica é estimar a dose de radiação ionizante absorvida pelos tecidos moles que se localizam nas trabéculas ósseas. Em função da dificuldade na obtenção de imagens micro-CT de amostras de ossos reais (OR), surgiu a

Soft tissue and water substitutes for megavoltage photon beams: An EGSnrc‐based evaluation [PDF]
Journal of Applied Clinical Medical Physics, 2016 In this work, soft‐tissue equivalence of water, polystyrene, PMMA and water equivalence of polystyrene, and PMMA has been assessed for multiple megavoltage photon beams and field sizes. EGSnrc based Monte Carlo (MC) codes, BEAMnrc and DOSXYZnrc are used for the linac head modeling and the phantom dose calculations, respectively. Percentage depth doses (
