In this paper, we study the radiation treatment planning optimization for Volumetric-Modulated Arc Therapy (VMAT). A nonlinear mixed integer programming model is formulated, then the linearization technique is used, and the resulting mixed integer programming model is solved by a heuristic approach based on the Nested-Partitions framework. The approach partitions the feasible region iteratively and...
In this paper we study the radiation treatment planning optimization for Volumetric-Modulated Arc Therapy (VMAT). A nonlinear mixed integer programming model is formulated considering dose rate change and MLC leaf speed constraints. Linearization technique is applied to this model, and the resulting mixed integer programming model is solved by heuristic approach based on Nested Partitions method....
In this paper we study the optimization problem for the radiation treatment planning of Volumetric-Modulated Arc Therapy (VMAT). Considering dose rate and MLC leafs as decision variables, we formulate the problem as nonlinear integer programming problem, which is very difficult to solve. A two-stage approach is proposed to tackle it, where in the first stage integer decision variables for MLC leafs...
