[ 1 ] - Size Effects of Gold and Iron Nanoparticles on Radiation Dose Enhancement in Brachytherapy and Teletherapy: A Monte Carlo Study
Introduction In this study, we aimed to calculate dose enhancement factor (DEF) for gold (Au) and iron (Fe) nanoparticles (NPs) in brachytherapy and teletherapy, using Monte Carlo (MC) method. Materials and Methods In this study, a new algorithm was introduced to calculate dose enhancement by AuNPs and FeNPs for Iridium-192 (Ir-192) brachytherapy and Cobalt-60 (Co-60) teletherapy sources, using...
[ 2 ] - تخمین آسیب DNA بافت بدن ناشی از دز تابشهای یونیزان در میدانهای بزرگ شتابدهنده خطی 6 مگاولتی فوتونی
Recent studies suggest that relative biological damage (RBD) may change from in to out of field regions for 6 MV photon beams. In this study RBD was calculated in and out of field of 30x30 cm2 and 40x40 cm2 6 MV clinical photon beams including low energy slowing down electrons in track length estimated method. Varian 2100C/D linear accelerator was simulated using MCNPX code. Electron and photon...
