Monte Carlo calculations of dose distribution for the treatment of gastric cancer with proton therapy
Proton therapy is a common form of external radiation therapy based on the manipulation of Bragg peak of this beam, it can treat the tumor by delivering high levels of doses to it, while protecting surrounding healthy tissues against radiation. In this work, the dose distribution of proton and secondary particles such as neutrons, photons, electrons and positrons in gastric cancer proton therap...
متن کاملA Track-repeating Algorithm for Fast Monte Carlo Dose Calculations of Proton Radiotherapy.
Monte Carlo codes are utilized for accurate dose calculations in proton radiation therapy research. While they are superior in accuracy to commonly used analytical dose calculations, they require significantly longer computation times. The aim of this work is to characterize a Monte Carlo track-repeating algorithm to increase computation speed without compromising dosimetric accuracy. The track...
متن کاملInvestigation and Comparison of Metal Nanoparticles on Dose Enhancement Effect in Radiotherapy Using Monte Carlo Simulation Method
Introduction: The main goal of radiation therapy is destroying the tumor so that the surrounded healthy tissues have received the least amount of radiation at the same time. In recent years, the use of nanoparticles has received much attention due to the increasing effects they can have on the deposited dose into the cancer cells. The aim of this study was to investigate the effects of nanopart...
متن کاملEvaluation of Lung Dose in Esophageal Cancer Radiotherapy Using Monte Carlo Simulation
Background and purpose: Radiation therapy make an important contribution in the control and treatment of cancers. Lungs are the main organs at risk in esophageal cancer radiotherapy. Difference between the dose distribution due to the treatment planning system (TPS) and the patient's body dose is dependent on the calculation of the treatment planning system algorithm, which is more pronounced i...
متن کاملModeling and dose calculations of a pure beta emitting 32P coated stent for intracoronary brachytherapy by Monte Carlo code
Background: Recently, different investigators have studied the possibility of radiation therapy in restenosis prevention and have shown promising results. In this study a unique radioactive source for intra vascular brachytherapy (IVBT) was investigated. The two-dimensional dose distribution in water for a 32P IVBT stent has been calculated. The pure beta emitter source 32P has been co...
