"We are excited to celebrate this key milestone after a decade of productive partnership with ViewRay. The ability to deliver on-table adaptive therapy with MRIdian has allowed us to deliver innovative cancer care to our patients to directly address the inevitable changes and movement that can take place inside the body," said Geoffrey Hugo, Ph.D., Professor of Radiation Oncology and Director of Medical Physics, at Siteman Cancer Center and Washington University School of Medicine. "This has brought us greater precision and control in our radiation delivery and truly changed how we treat our patients."
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.

About ViewRay
ViewRay, Inc. (Nasdaq: VRAY) designs, manufactures and markets the MRIdian® MRI-Guided 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 concerns that potentially may arise when high magnetic fields interact with radiation beams.
