Radiation therapy presents an effective and non-invasive option for cancer treatment. However, the use of ionizing radiation can also be harmful and the effects and side-effects of irradiation need to be balanced. We develop algorithms and systems to identify the optimal trade-off among the various objectives, e.g., dose in the target, dose in critical structures, or treatment time.
