Advanced radiation therapy delivery techniques have the potential to deliver the required doses to the tumor while minimizing the dose to healthy normal tissue. However, these advancements require highly conformal dose delivery and without effective motion management techniques such therapies can be sub-optimal. In this work we explore the feasibility of using cine-MRI images acquired in conjunction with the real-time external surrogates to assist in the development of a robust model for real-time tumor displacement prediction.
