[ 1 ] - بررسی کاهش مقدار عدم قطعیت محاسبات مونت‌کارلو دوز در شبیه‌سازی شتاب‌دهنده خطی بالینی Oncor®بااستفاده از تکنیک کاهش واریانس DBS در کدمونت‌کارلو BEAMnrc
Purpose: To study the benefits of Directional Bremsstrahlung Splitting (DBS) dose variance reduction technique in BEAMnrc Monte Carlo (MC) code for Oncor® linac at 6MV and 18MV energies. Materials and Method: A MC model of Oncor® linac was built using BEAMnrc MC Code and verified by the measured data for 6MV and 18MV energies of various field sizes. Then Oncor® machine was modele...
[ 2 ] - Investigation of The Effect of Radiosensitization of Tungsten Oxide Nanoparticles on AGS Cell Line of Human Stomach Cancer in Megavoltage Photons Radiation
Radiotherapy which consists of external beam radiotherapy (EBRT) and internal radioisotope therapy (RIT), has a wide usage for treating cancer as clinical trials.This study provides some conditions to prove that tungsten oxide nanoparticles (WO3) is a radiosensitizer.The peripheral blood mononuclear cells (PBMCs) were used to calculate inhibitory concentration (IC).The AGS cell line exposed the...
[ 3 ] - The use of EBT3 film and Delta4 for the dosimetric verification of EclipseTM treatment planning system in a heterogeneous chest phantom: an IMRT technique
Background: This study aimed to evaluate the dose calculation accuracy of EclipseTM treatment planning system (TPS) in a heterogeneous chest phantom with the intensity modulated radiotherapy (IMRT) technique using EBT3 film and Delta4. Materials and Methods: Two IMRT plans (A and B) were prepared for radiotherapy of the heterogeneous chest phantom. Plan A was between the left lung and the surro...
