A Monte Carlo Study on Dose Enhancement by Homogeneous and Inhomogeneous Distributions of Gold Nanoparticles in Radiotherapy with Low Energy X-rays
Background: To enhance the dose to tumor, the use of high atomic number elements has been proposed.Objective: The aim of this study is to investigate the effect of gold nanoparticle distribution on dose enhancement in tumor when the tumor is irradiated by typical monoenergetic X-ray beams by considering homogeneous and inhomogeneous distributions of gold nanoparticles (GNPs) in the tumor.Method...
متن کاملMonte Carlo Dose Algorithm
Conventional dose calculation algorithms, such as Pencil Beam are proven effective for tumors located in homogeneous regions with similar tissue consistency such as the brain. However, these algorithms tend to overestimate the dose distribution in extracranial regions such as in the lung and head and neck regions where large inhomogeneities exist. Due to the inconsistencies seen in current calc...
متن کاملMonte Carlo computation of dose deposited by carbon ions in radiation therapy
Background: High-velocity carbon ion beams represent the most advanced tool for radiotherapy of deep-seated tumors. Currently, the superiority of carbon ion therapy is more prominent on lung cancer or hepatomas. Materials and Methods: The data for lateral straggling and projected range of monoenergetic 290 MeV/u (3.48 GeV) carbon ions in muscle tissue were obtained from the stopping and range o...
متن کاملMonte Carlo Simulation of the Electron Beams Produced by a Linear Accelerator for Intra- Operative Radiation Therapy
In this work, organized as a short review, we present some results obtained by applying the Monte Carlo techniques in the Intra-Operative Radiation Therapy (IORT). The electron beams generated by the NOVAC7 IORT accelerator have been simulated using BEAMnrc/EGSnrc Monte Carlo code, the dose distributions and water-to-air stopping power ratios being later calculated with the associated software ...
