AbstractWe present a case of refractory mycosis fungoides (MF) that responded to low-dose localised electron radiotherapy. A 59-year-old man presented with a 5-year history of a generalised, pruritic, scaly, red skin rash that had recently become more nod... see more

Objective: Studying of the fundamental dosimetric characteristics of metal oxide semiconductor field effect transistor (MOSFET) detectors to evaluate its use in clinical electron beam irradiations.Materials and Methods: In this study, GE-MS Saturne-43 li... see more

Introduction: Radiation therapy using electron beams is a promising method due to its physical dose distribution. Monte Carlo (MC) code is the best and most accurate technique for forespeaking the distribution of dose in radiation treatment of patients.Ma... see more

Objective: The aim of this study is to evaluate the effect of tissue composition on dose distribution in electron beam radiotherapy.Methods: A Siemens Primus linear accelerator and a phantom were simulated using MCNPX Monte Carlo code. In a homogeneous cy... see more

Radiochromic film dosimetry has been commonly used for determination of dose measurement in radiotherapy for many years because of their high spatial resolution, low energy dependence and its approximate tissue equivalent. Additionally, it has other pract... see more

Introduction: Glass phosphors are broadly used to determine patient doses in radiation diagnostic and radiotherapy because of their good features, the dose ranges of interest are approximately  0.1 -100 mGy for clinical x-ray diagnostics, and 1-5Gy f... see more

The accuracy of treatment field size in is a success key in cancer radiotherapy. As Increase in dose may lead to overdose side effects, and decrease in dose lead to subtherapeutic effect which increased incidence of tumor recurrence or incomplete recovery... see more

Background: As hypofractionated radiotherapy for post-operative breast cancer patients safe, effective and more convenient, it might be beneficial for patients of developing countries like ours. Objective: This study was done to evaluate the safety and ef... see more

Background: Gold nanoparticles (GNPs) are among the most promising radiosensitive materials in radiotherapy. Studying the effective sensitizing factors such as nanoparticle size, concentration, surface features, radiation energy and cell type can help to ... see more
