The Impact of Nano-Sized Gold Particles on the Target Dose Enhancement Based on Photon Beams Using by Monte Carlo Method
Objective(s): In this study we evaluate the impact of the different aspects of Gold Nano-Particles (GNPs) on the target absorptive Dose Enhancement Factor (DEF) during external targeted radiotherapy with photon beams ranging from kilovolt to megavolt energies using Monte Carlo simulation. Methods: We have simulated the interaction of photon beams wi...
متن کاملRadiation dose enhancement in skin therapy with nanoparticle addition: A Monte Carlo study on kilovoltage photon and megavoltage electron beams
AIM To investigated the dose enhancement due to the incorporation of nanoparticles in skin therapy using the kilovoltage (kV) photon and megavoltage (MV) electron beams. Monte Carlo simulations were used to predict the dose enhancement when different types and concentrations of nanoparticles were added to skin target layers of varying thickness. METHODS Clinical kV photon beams (105 and 220 k...

متن کاملMegavoltage dose enhancement of gold nanoparticles for different geometric set-ups: Measurements and Monte Carlo simulation
Background: Gold nanoparticles (GNPs) have been shown as a good radiosensitizer. In combination with radiotherapy, several studies with orthovoltage X-rays have shown considerable dose enhancement effects. This paper reports the dose enhancement factor (DEF) due to GNPs in 18 megavoltage (MV) beams. Materials and Methods: Different geometrical 50-nm GNPs configurations at a concentrati...
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...
