ViewRay Surpasses 50th Order for MRIdian® System for Precision Cancer Treatment

Milestone Demonstrates Rapid Adoption of Next-Generation MR-Image Guided Radiation Therapy
CLEVELAND, March 27, 2018 /PRNewswire/ — ViewRay, Inc. (Nasdaq: VRAY) announced that the company surpassed its 50th MRIdian MR image-guided radiation therapy system order during the first quarter of 2018 – a landmark achievement in the company’s history of bringing next-generation technology to the fight against cancer.

“The radiation oncology community has long awaited the integration of MR image-guidance with radiation delivery,” said Chris Raanes, president and CEO of ViewRay. “This breakthrough allows radiation oncologists to visualize soft tissue tumors in high definition, for the first time ever, while simultaneously and dynamically controlling radiation delivery to the patient. This remarkable achievement represents what we believe is the future of radiation therapy.”

ViewRay’s MRIdian is the only FDA-cleared and CE-marked MR-image guided radiation therapy system. Unlike conventional radiotherapy, the MRIdian system provides diagnostic-quality MR visualization of soft-tissue targets and surrounding organs. This recent technological advance enables daily on-table treatment plan adaptation to quickly and dynamically adjust for subtle anatomical changes that may occur, both during treatment delivery and throughout the course of treatment. Combined, these capabilities provide the potential for clinicians to improve targeting precision and thus deliver higher, and potentially more effective, radiation doses.

The 50th and subsequent 51st order were placed by RAD Technology Medical Systems, which provides revolutionary modular building systems for the healthcare industry including equipment and leasing options. RAD’s unique leasing options enable healthcare institutions to secure facilities and state-of-the-art technology, like MRIdian Linac, without lengthy capital procurement challenges and debt impairment.
