Evaluation of target and cardiac position during visually monitored deep inspiration breath‐hold for breast radiotherapy
A low-resource visually monitored deep inspiration breath-hold (VM-DIBH) technique was successfully implemented in our clinic to reduce cardiac dose in left-sided breast radiotherapy. In this study, we retrospectively characterized the chest wall and heart positioning accuracy of VM-DIBH using cine portal images from 42 patients. Central chest wall position from field edge and in-field maximum ...
متن کاملDosimetric and clinical advantages of deep inspiration breath-hold (DIBH) during radiotherapy of breast cancer
BACKGROUND To investigate the potential dosimetric and clinical benefits of Deep Inspiration Breath-Hold (DIBH) technique during radiotherapy of breast cancer compared with Free Breathing (FB). METHODS Eight left-sided breast cancer patients underwent a supervised breath hold during treatment. For each patient, two CT scans were acquired with and without breath hold, and virtual simulation wa...
متن کاملDosimetric effects of intrafractional isocenter variation during deep inspiration breath‐hold for breast cancer patients using surface‐guided radiotherapy
The aim of this study was to investigate potential dose reductions to the heart, left anterior descending coronary artery (LAD), and ipsilateral lung for left-sided breast cancer using visually guided deep inspiration breath-hold (DIBH) with the optical surface scanning system Catalyst™, and how these potential dosimetric benefits are affected by intrafractional motion in between breath holds. ...
متن کاملChallenges of maintaining breath-hold conformity for breast patients while using the deep inspiration breath-hold technique
Deep inspiration breath-hold (DIBH) is used for whole breast radiotherapy, as a means of providing better dose homogeneity. This can be achieved by lower doses to the organs at risk, less patient movement and better set up. Most patients offered DIBH treatment are left-sided breast cancer, or ductal carcinoma in situ (DCIS) patients, due to the proximity of the heart to the chest wall so it is ...
متن کاملCardiac Dose Reduction with Deep-Inspiratory Breath Hold Technique of Radiotherapy for Left-Sided Breast Cancer
INTRODUCTION Different techniques of radiation therapy have been studied to reduce the cardiac dose in left breast cancer. AIM In this prospective dosimetric study, the doses to heart as well as other organs at risk (OAR) were compared between free-breathing (FB) and deep inspiratory breath hold (DIBH) techniques in intensity modulated radiotherapy (IMRT) and opposed-tangent three-dimensional...
