A new kind of medical technology company

ViewRay™ Incorporated of Cleveland, Ohio, is a privately held medical device company developing advanced radiation therapy technology for the treatment of cancer. With the ViewRay system, physicians have more control over the delivery of their radiation therapy prescriptions. ViewRay technology provides continuous soft-tissue imaging during treatment, using MRI-guided radiation therapy, so that clinicians can see the target, monitor the radiation dose, and adapt to changes in the patient’s anatomy—all in real time. 

ViewRay holds the exclusive worldwide license for its combination of MRI and radiation therapy technologies. MRI-guided radiation therapy was conceived by company founder James F. Dempsey, PhD, while he was a member of the radiation oncology faculty at the University of Florida in 2004. University of Florida leaders encouraged Dempsey to bring his invention to the marketplace, where it could potentially benefit cancer patients, and ViewRay was formed.

In 2011, landmark patents were issued for ViewRay’s core technology in both the United States and Europe. Broadly covering both the medical instrument and the method of implementation, the patents acknowledge the unique combination of simultaneous MRI and radioisotope irradiation.
