VA Oklahoma City Healthcare System Chooses ViewRay's MRIdian® MRI-Guided Radiation Therapy System

June 13, 2023

First cancer center in Oklahoma and fourth VA medical center to offer advanced MRI-guided radiation therapy to treat cancer.

DENVER, June 13, 2023 /PRNewswire/ -- ViewRay, Inc. (Nasdaq: VRAY) announced today that the VA Oklahoma City Healthcare System has selected MRIdian MRI-guided radiation therapy system to expand radiation therapy services at the Oklahoma City VA Medical Center. This will be the first cancer center in Oklahoma and the fourth VA medical center offering Veterans access to MRIdian's advanced MRI-guided radiation therapy to treat cancer. The MRIdian system will enable the Oklahoma City VA Medical Center to provide precision MRI-guided radiation therapy technology to Veterans seeking personalized treatment for a broad range of cancer, including pancreas, prostate, lung, liver, breast, and oligometastatic disease. Other VA medical centers that will be offering MRIdian MRI-guided radiation therapy include Louis Stokes Cleveland Medical Center (VA Northeast Ohio Healthcare System), Lt. Colonel Charles S. Kettles VA Medical Center (VA Ann Arbor Healthcare System), and Michael E. DeBakey Medical Center (VA Houston Healthcare system).

The Veterans Health Administration is America's largest integrated healthcare system, providing care at 1,298 healthcare facilities, including 171 medical centers. The VA is leading the fight against cancer through precision oncology by developing and applying new technologies, tools, research knowledge, and best-practice therapies. Their scientific and medical breakthroughs are shared inside and outside their healthcare system to benefit Veterans and all Americans.

"ViewRay is proud to be working with VA Oklahoma City Healthcare System, a talented group of clinicians committed to bringing patients the benefit of precise and personalized radiation therapy," said Paul Ziegler, ViewRay Executive Vice President and CCO. "We are excited to see another VA healthcare system join the growing MRIdian community. Expanding the availability of MRIdian's short-course non-invasive therapy with fewer side effects and better quality of life is an important advancement for our Veterans."

The MRIdian system provides oncologists with outstanding anatomical visualization through diagnostic-quality MR images and the ability to adapt a radiation therapy plan to the targeted cancer with the patient on the table. This combination allows physicians to define tight treatment margins to avoid unnecessary radiation exposure of vulnerable organs-at-risk and healthy tissue and allows the delivery of ablative radiation doses in five or fewer treatment sessions without relying on implanted markers. MRIdian enables automatic gating of the radiation beam if the target moves outside the user-defined margins by providing continuous real-time tracking of the target and organs at risk. This allows for delivering the prescribed dose to the target while sparing surrounding healthy tissue and critical structures. This results in minimizing toxicities typically associated with conventional radiation therapy.

To date, over 31,000 patients have been treated with MRIdian. Currently, 62 MRIdian systems are installed at hospitals around the world, where they are used to treat a wide variety of solid tumors and are the focus of numerous ongoing research efforts. MRIdian has been the subject of hundreds of peer-reviewed publications, scientific meeting abstracts, and presentations. For a list of treatment centers, please visit:

Safety Statement
The MRIdian Linac System is not appropriate for all patients, including those who are not candidates for magnetic resonance imaging. Radiation treatments may cause side effects that can vary depending on the part of the body being treated. The most frequent ones are typically temporary and may include, but are not limited to, irritation to the respiratory, digestive, urinary, or reproductive systems; fatigue; nausea; skin irritation; and hair loss. In some patients, side effects can be severe. Treatment sessions may vary in complexity and duration. Radiation treatment is not appropriate for all cancers. You should discuss the potential for side effects and their severity as well as the benefits of radiation and magnetic resonance imaging with your doctor to make sure radiation treatment is right for you.
