MCO treatment planning works by creating a database of plans, each emphasizing a different objective. These plans are then used to determine the best compromise between specified clinical and planning criteria. And while traditional treatment planning offers no fast and easy way to explore trade-offs in dose to different structures, the MCO-generated plans can be easily navigated using sliders, to create the optimal plan far faster.

In this short film by our sister publication Physics World, James Dacey visits MGH to meet the researchers and doctors who are pioneering this initiative.
