Abstract:Purpose: To systematically study the effects of computation details on DVH accuracy for the first time in a teletherapy planning context, measure the effect sizes of different parameters and make recommendations for quality assurance in multicentric studies. Methods: We defined two IMRT plans (maximum doses: 84/79 Gy) on a physical phantom (using a commercial TPS) and exported five dose volumes with different resolutions (1 * 1 * 0.83 mm^3, 2 * 2 * 2.5 mm^3, 3 * 3 * 2.5 mm^3, 4 * 4 * 5 mm^3, 5 * 5 * 5 mm^3) an… 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.
