SU-E-T-430: Modeling MLC Leaf End in 2D for Sliding Window IMRT and Arc Therapy.

Abstract

PURPOSE To develop a 2D geometric model for MLC accounting for leaf end dose leakage for dynamic IMRT and Rapidarc therapy. METHODS Leaf-end dose leakage is one of the problems for MLC dose calculation and modeling. Dosimetric leaf gap used to model the MLC and to count for leakage in dose calculation, but may not be accurate for smaller leaf gaps. We… (More)
