ViewRay™ MRI-guided radiation therapy system


vr_homepage_20120530
ViewRay™ Incorporated, a privately held medical device company, has received U.S. FDA 510(k) premarket notification clearance for its MRI-guided radiation therapy system. The ViewRay system features a unique combination of radiotherapy delivery and simultaneous magnetic resonance imaging (MRI) for the treatment of cancer. ViewRay’s treatment planning and delivery software received 510(k) premarket notification clearance in 2011.
“FDA clearance of our integrated system is a major milestone in the development of our technology,” said ViewRay President and CEO Gregory M. Ayers, MD, PhD. “It has already been an exciting year for ViewRay, with an additional round of funding and the installation of our first research systems at major U.S. medical centers. Early clinical imaging studies have verified the quality of the system’s MR images, and now we’re looking forward to clinical applications.” The ViewRay system provides continuous soft-tissue imaging during treatment so that clinicians can see and record precisely where radiation therapy is being delivered, as it’s being delivered.ViewRay’s patented cancer treatment technology was invented by company founder James F. Dempsey, PhD, while he was a member of the radiation oncology faculty at the University of Florida. “ViewRay began with the idea that we need to see what exactly we’re doing when we treat cancer patients with radiation therapy,” said Dempsey, now ViewRay’s chief scientific officer. “Thanks to our clear vision, an outstanding engineering team, and dedicated leadership, we’re now able to bring that idea into the clinic, where it can help cancer patients.”
Potential clinical applications
ViewRay researchers are studying the motion of tumors in lung, prostate, liver, head and neck, and other types of cancer where MRI-guided radiotherapy could offer sophisticated treatments.
