Requirements for Online Adaptive RT

 Daily volumetric imaging (CBCT, in-room CT, onboard MRI …)  Fast and robust image segmentation methods  Fast re-planning  Work in progress  MRIdian  Hybrid methods (e.g. aperture morphing, segment optimization)  Plan-library based methods  Use a pre-treatment established motion model to compute configurations of the target volume and organs at risk  Simple method: margin-of-the-day Fast, robust, highly automated, and failsafe
