Abstract:Purpose: The delivery time for an intensity‐modulated radiation therapy plan using the step‐and‐shoot method may be impractical for complex beam profiles that require a large number of segments. We propose a fast smoothing algorithm which smooths a beam profile to integer‐valued intensities. Method and Materials: An integer program was formulated that smooths a beam profile to integer‐valued intensities. The user specifies the permitted intensity level values, the maximum number of intensity levels, and the pe… 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.
