For the first time, cancer patients in New England will have a cutting-edge option for radiation treatment, known as MRI-Guided Radiation Therapy (MRI-RT). This video highlights the two components of the new MRI-RT, a 3 Tesla MRI scanner modified for radiation therapy planning called the MR Advanced Procedure and Simulation (MAPS) unit and an integrated MRI-guided linear accelerator (MRI-LINAC). The MAPS unit includes a high-field strength (3.0T) magnet for diagnostic quality imaging for initial radiation therapy planning. The MRI-LINAC, meanwhile, is a state-of-the-art hybrid device that integrates a modified, lower-field (0.35T) MRI scanner with a linear accelerator (radiation delivery machine) to reduce the magnetic interference on the radiation beam.
