Abstract

Motion management on MR-Linacs ranges from the utilization of immobilization devices to gating the radiation beam based on tumor position. The overall goal of motion management is to have greater precision and accuracy in the treatment of tumors and reduce dose to healthy tissue. In this chapter, the different types of motion encountered in radiation therapy are described, a review of X-ray- and CT-based motion management approaches, motion management techniques using an MR-Linac, and, in detail, how motion is assessed and motion management strategies implemented throughout the radiation therapy workflow.
