Miami Cancer Institute to Acquire ViewRay’s MRIdian Linac for MRI-Guided Radiation Therapy

7/27/17

Miami, July 27, 2017 (GLOBE NEWSWIRE) --Miami Cancer Institute, part of Baptist Health South Florida, announced today that it will acquire ViewRay’s MRIdian Linac System, the world’s first and only FDA-cleared MRI-guided radiation therapy system. The MRIdian system will be part of the healthcare organization’s new Miami Cancer Institute, a multidisciplinary, destination cancer center and member of the Memorial Sloan Kettering Cancer Alliance. The MRIdian treatments are expected to be available for patient care in spring 2018.

Nearly two-thirds of all treated cancer patients in the United States will receive some form of radiation therapy during the course of their illness, according to estimates by the American Society for Radiation Oncology. The movement of tumors and internal organs makes precision radiation delivery a challenge, but through the use of MRI-guidance, clinicians are better able to aim radiation therapy directly at tumors while avoiding surrounding tissues.

MRIdian Linac provides a unique combination of simultaneous radiation therapy delivery and continuous magnetic resonance imaging (MRI) for the treatment of cancer. Because MRI technology eliminates the radiation exposure associated with computed tomography (CT) scans, MRIdian Linac allows for continuous imaging during the delivery of radiation therapy, allowing physicians to directly view and target the tumor during treatment. MRIdian Linac also enables physicians to personalize the treatment based on changes in the shape or location of the tumor and surrounding tissues using on-table adaptive therapy.

Miami Cancer Institute welcomes the ViewRay MRIdian Linac to its already comprehensive fleet of highly sophisticated radiation delivery systems in the Department of Radiation Oncology, becoming the first in Florida to do so.

“By capitalizing on the improved soft tissue visualization and leveraging the real-time imaging capability of MR, radiation oncologists at Miami Cancer Institute will utilize this technology to target mobile tumors such as those located in the lung, liver and pancreas,” said Minesh Mehta, M.D., chief of radiation oncology at Miami Cancer Institute. “By having the ability to visualize tissues simultaneously during treatment delivery, which cannot easily be done on other radiation treatment machines, we are able to track these mobile tumors and minimize the exposure of adjacent, normal tissues through adaptive planning.”

Additionally, says Mehta, the reduction of “motion margin” will “decrease the volume of normal tissue irradiated to high doses, thereby providing an opportunity to decrease side effects.”

Due to the novelty of this technology, a number of opportunities present themselves to optimize the clinical applications of the MRIdian Linac. Clinical researchers at Miami Cancer Institute plan to investigate the impact of continuous, MRI-guided soft tissue tracking on margin reduction as well as investigate the need for adaptive radiotherapy when accounting for changes due to organ motion.
