Baptist Health South Florida to Acquire a Second ViewRay MRIdian® MR-Guided Radiation Therapy System

Novel MR Image-Guided Radiotherapy Enables High-Definition Tumor Visualization and On-table Adaptive Cancer Treatment

CLEVELAND, April 30, 2018 /PRNewswire/ — ViewRay, Inc. (Nasdaq: VRAY) announced today that Miami Cancer Institute at Baptist Health South Florida has begun patient treatments using the company’s next generation MR image-guided radiation therapy system, MRIdian® Linac, making it the second institution in the United States to treat patients with the new linear accelerator-based system. The MRIdian Linac is part of the new Miami Cancer Institute, a destination cancer center known for its leading clinical care, compassionate patient experience, clinical research, and state-of-the-art technology. It is also the only member of the Memorial Sloan Kettering Cancer Alliance in the southeastern United States.

MRIdian is the world’s first and only FDA-cleared MR image-guided radiation therapy system. It provides a unique combination of continuous magnetic resonance imaging (MRI) and simultaneous radiation therapy delivery for the treatment of cancer. MRI improves tumor visibility by clearly defining the targeted tumor from the surrounding soft tissue and other critical organs. The ability to see both the tumor and surrounding organs constantly throughout radiation delivery allows doctors to personalize treatment based on changes in the shape or location of the tumor and surrounding tissues using on-table adaptive therapy. As a result, doctors can quickly respond to subtle anatomical changes observed on a day-to-day basis and reshape the dose to better match the current contours of the tumor.

“Effective treatment of tumors that move, such as those in the lung, liver and pancreas, has been a long-standing challenge for radiation oncologists, often requiring difficult trade-offs in targeting, dosing and tissue sparing, or rendering patients untreatable with radiation,” said Minesh Mehta, M.D., Deputy Director and Chief of Radiation Oncology at Miami Cancer Institute. “With MRIdian Linac, we can visualize the tumor and surrounding tissues simultaneously during treatment delivery – something that’s not feasible on other radiation therapy machines – and thereby track these mobile tumors allowing us to minimize the exposure of adjacent, normal tissues by modifying the treatment plan. Ultimately we believe this will help to improve outcomes and decrease side effects for our patients.”

About ViewRay
ViewRay®, Inc. (Nasdaq: VRAY), designs, manufactures and markets the MRIdian® radiation therapy system. MRIdian is built upon a proprietary high-definition MR imaging system designed from the ground up to address the unique challenges and clinical workflow for advanced radiation oncology. Unlike MR systems used in diagnostic radiology, MRIdian’s high-definition MR was purpose-built to address specific challenges including beam distortion, skin toxicity, and other safety concerns, which may potentially occur when high magnetic fields interact with radiation beams.
