[ 1 ] - بررسی اثر ناهمگنی بافت استخوان بر توزیع دز چشمه‌ی براکی‌تراپی 103Pd مدل MED3633 به روش مونت‌کارلو
The determination of the dosimetry parameters of brachytherapy in the treatment of cancerous tumors as per the TG-43U1 protocol provided by the American Association of Physicists in Medicine should be done in the surrounding water source before clinical application. To achieve a good treatment result, various factors such as body tissues with different densities can have a decisive role so that...
[ 2 ] - محاسبه درصد خطای به وجود آمده در استفاده از فانتوم آب به جای بافت نرم برای توزیع چشمه براکی‌تراپی 103Pd به روش مونت‌کارلو
Introduction: 103Pd is a low energy source, which is used in brachytherapy. According to the standards of American Association of Physicists in Medicine, dosimetric parameters determination of brachytherapy sources before the clinical application was considered significantly important. Therfore, the present study aimed to compare the dosimetric parameters of the target source using the water ph...
[ 3 ] - The study of dose gamma rays of 192Ir source on DNA single strand break (SSB) and DNA double strand break (DSB) in soft tissue phantom
Introduction: Passage of ionizing radiation through the organs of living creatures develops clusters of damaged nucleotides inside the DNA rounds. 192Ir Gamma source is one of the most widely used sources in brachytherapy of cervical and prostate cancer. Thus, in this research, we investigated the flux of photons and its resulting secondary electrons, the single-strand break (S...
[ 4 ] - Increased Absorption Dose with the Presence of Gold Nano particles in a Normoxic Polymer Gel: Method Monte Carlo
Introduction: Radiotherapy involves all methods that can provide a special amount of ionizing radiation to malignant tissue with the assumption that minimal damage to healthy tissues is achieved. We are looking for a valuable and reliable method to measure the absorption dose and also the ability to measure the absorption dose distribution in three dimensions, which today is th...
[ 5 ] - The Comparison of the shares of stopping power in a soft tissue-equivalent material
Introduction: Proton therapy is a type of radiation treatment that it uses protons to treat cancer. Because of the protons’ unique ability to distribute the radiation dose more directly to the tumor, it minimizes the damage to nearby healthy tissues. The rate of energy loss by the ion in the target is called stopping power. The total stopping power is sum nuclear and electroni...
[ 6 ] - The dosimetry assessment of Varian Linear Accelerators of 6, 15 and 20 MV by Monte Carlo Method
Introduction: Monte Carlo method is often applied in radiation therapy as utilized in all the branches of science. An important requirement for successful radiotherapy is carefully examine the dose distribution specifications and decrease the difference between these features with experience to an acceptable level. In this study, the characteristics of 6, 15 and 20 MeV incident x-rays are prov...
[ 7 ] - Investigation of dose distribution 252Cf Isotron brachytherapy source based on TG-43U1 protocol by Monte Carlo method
Introduction:The commercial 252Cf sources are too large in size and clinical applications of neutronbrachytherapy (NBT) are limited to a small number of intracavitary treatments of cervical cancers. Recently, under the Cooperative Research and Development Agreement (CRADA) with Isotron Inc., the Oak Ridge National Laboratory (ORNL) encapsulated a new medical 252Cf sources, cal...
