TU‐EE‐A2‐04: Increasing the Efficiency and Radiobiological Relevance of IMRT Treatment Planning: Replacing Dose‐Volume Thresholds with Generalized Equivalent Uniform Dose Or Mean‐Tail‐Dose Metrics
Abstract:Purpose: Our goal is to validate treatment planning metrics that are computationally efficient yet have inherent radiobiological meaning, either directly or by correlating highly with more explicitly biological metrics. We show how mean‐tail‐dose and the generalized equivalent uniform dose (gEUD) metrics could be used to replace dose‐volume metrics in IMRT treatment planning. Method and Materials: gEUD and MOH/MOCx (mean of the hottest/coldest x% of a structure) are candidates for dose‐volume metric replacemen… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
