Synopsis
MR applications in radiation therapy has shown great promise for highly conformal treatment. However, MRgRT in the abdomen remains challenging due to motion and the sheer number of organs. In this work, we have demonstrated an integrated multi-task MR platform for adaptive radiation planning and treatment monitoring in the abdomen. In our proposed framework, from a single "pre-beam" scan we are able to generate a volumetric, multi-contrast and motion resolved images for adaptive treatment planning as well as enabling multi-contrast 3D real-time display during treatment. We demonstrate this capability in 3T and 0.55T.
