Title: Robust Intensity-Modulated Radiation Therapy Treatment Planning
Joint work with Millie Chu, Yuriy Zinchenko and Michael B. Sharpe

Abstract: The radiation therapy treatment planning problem involves devising a radiation treatment plan that delivers a sufficient dose to a target region containing the tumour while sparing, as much as possible, surrounding organs. Traditional treatment planning models handle uncertainties arising from organ motion etc. by inflating the target region. We instead use a probabilistic model and show that it is equivalent to using robust linear programming. For a sample prostate case, our results show that the method is computationally feasible, and finds plans that are more adept at sparing healthy tissue while maintaining the prescribed dose. We discuss the method, and our efforts to reduce its computational requirements.
