Optimization of three dimensional planning dosimetric in breast phantom for match region of supraclavicular and tangential fields.
AIM Complex geometry of breast tissue causes perturbation in dose distribution. This problem can beget overdose or under-dose points in match region of three fields. The aim of this study is to create dose homogeneity distribution in match region between tangential and supraclavicular fields (SCF) with Gafchromic external beam therapy (EBT) film. MATERIALS AND METHODS In this study, an anatom...
متن کاملOptimization of 3D Planning Dosimetry in a Breast Phantom for the Match Region of Supraclavicular and Tangential Fields
Introduction: The complex geometry of breast and also lung and heart inhomogeneities near the planning target volume (PTV) result in perturbations in dose distribution. This problem can result in overdosage or underdosage in the match region of the three treatment fields. The purpose of this study is to create a homogeneous dose distribution in the match region between the supraclavicular and t...

متن کاملoptimizing of the tangential technique and supraclavicular fields in 3 dimensional conformal radiation therapy for breast cancer
radiotherapy plays an essential role in the management of breast cancer. three-dimensional conformal radiation therapy (3d-crt) is applied based on 3d image information of anatomy of patients. in three-dimensional conformal radiation therapy (3d-crt) for breast cancer one of the common techniques is tangential technique. in this project, various parameters of tangential and supraclavicular fiel...
متن کاملVerifying monitor unit calculations for tangential whole‐breast fields in three‐dimensional planning
An essential component of quality assurance in radiation therapy is verifying the accuracy of monitor unit calculations. For tangential breast fields, monitor unit differences between primary calculations and second checks are usually larger than considered acceptable at other anatomical sites. A simple model to reconcile the differences between sophisticated and simple algorithms is presented,...
