Purpose This study aimed to improve the understanding of deviations between planned and
accumulated doses and to establish metrics to predict clinically significant dosimetric …

Purpose To estimate the delivered dose to targets and organs at risk for head and neck
radiation therapy by accumulating the dose using 3 deformable image registration (DIR) …

Purpose Doses actually delivered to the parotid glands during radiation therapy often
exceed planned doses. We hypothesized that the delivered doses correlate better with …

Background and purpose Deformable image registration (DIR) facilitated dose
reconstruction and accumulation can be applied to assess delivered dose and verify the …

Purpose The purpose of this study was to systematically monitor anatomic variations and
their dosimetric consequences during intensity modulated radiation therapy (IMRT) for head …

BACKGROUND AND PURPOSE: Weight loss, tumor shrinkage, and tissue edema induce
substantial modification of patient's anatomy during head and neck (HN) radiotherapy (RT) …

Background and purpose Anatomical changes induce differences between planned and
delivered dose. Adaptive radiotherapy (ART) may reduce these differences but the optimal …

PURPOSE: Significant anatomic and volumetric changes occur in head and neck cancer
patients during fractionated radiotherapy, and the actual dose can be considerably different …

Purpose: To quantify the trade-off between parotid gland sparing and planning target
volume (PTV) underdosages for head-and-neck intensity-modulated radiotherapy. Methods …

Background Head and neck cancers are commonly treated with radiation therapy, but due to
possible volume changes, plan adaptation may be required during the course of treatment …
