The Effects of Nonmagnetic Bolus on Contralateral Breast Skin Dose during Tangential Breast Irradiation Therapy
In this study the contralateral breast skin dose was decreased. It was to apply the results to the clinical study after analysis of different radiation dose amounts to contralateral breast with nonmagnetic bolus and without nonmagnetic bolus. A Rando phantom was computed tomography (CT) simulated, five treatment plans were generated: open tangents, open field in field, wedge 15, wedge 30, and i...
متن کاملDose-volume Analysis of Heart and Lung during 3D planning of Tangential Breast Cancer Irradiation
Background: Breast cancer is becoming more frequently diagnosed at early stages with improved long term outcomes. Radiation-related heart disease and lung cancer can occur following radiotherapy for breast cancer. The aim of this study was to evaluate some dosimetric parameters of heart and lung during whole breast radiotherapy. Methods:Twenty five consecutive...

15 صفحه اولOptimization of tangential fields arrangement in the breast cancer 3D conformal radiation therapy
Introduction: The incidence of breast cancer increases with the rate of 1-2% at the world. Radiation therapy is one of the available choices for breast cancer treatment. The single isocentre half-beam block technique is considered as a standard technique to avoid hot and cold spots within the PTV. The major advantage of half beam technique is that the both contralateral breast...
