Abstract

We are developing a new approach to optimize Intensity Modulated Radiation Therapy plans in the presence of uncertainty. We first present a problem formulation to describe the stochastic or semi-robust problem. Unfortunately, this formulation is infeasible to solve in a reasonable time on modern computers. We recognized this and developed a randomized algorithm approach using voxel sampling to solve the problem quickly. This approach turns out to be useful for solving normal IMRT optimization problems as well.
