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

Monte Carlo analysis of energy deposition and X-ray fluence in cylindrical anode systems. [PDF]
J Appl Clin Med PhysAbstract Background Cylindrical anode X‐ray systems are increasingly used in multisource imaging; however, electron beam interactions with the curved anodes cause geometric distortions that alter energy deposition and X‐ray emission. Understanding these effects is key to optimizing system performance.
