Abstract
A device for optimizing a radiation therapy plan () for delivering therapeutic radiation to a patient using a therapeutic radiation source () while modulated by a multi-leaf collimator (MLC) () includes at least one electronic processor () connected to a radiation therapy device (). A non-transitory computer readable medium () stores instructions readable and executable by the at least one electronic processor to perform a radiation therapy plan optimization method () including: optimizing MLC settings of the MLC respective to an objective function wherein the MLC settings define MLC leaf tip positions for a plurality of rows of MLC leaf pairs at a plurality of control points (CPs). The optimizing is performed in two or more iterations with a resolution of the MLC settings increasing in successive iterations.
