First Patients Treated with ViewRay’s MRIdian Linac System at Henry Ford Health System

World’s First FDA-Cleared MRI-guided Linear Accelerator-based Radiation Therapy System
Now Treating Patients

CLEVELAND, July 20, 2017 – ViewRay, Inc. (Nasdaq: VRAY)announced today that the first cancer patients have been treated using the company’s MRIdian Linac system at Henry Ford Health System in Metro Detroit. MRIdian Linac is the world’s only FDA-cleared MRI-guided radiation therapy system with linear accelerator-based delivery. MRIdian Linac is the company’s second generation system, building on the success of the company’s first generation system which has been used to treat more than 1,500 patients.


“MRIdian offers us the ability to finally see where the patient’s tumor is located in real time using MRI imaging so we know what changes are taking place inside the body and can make the necessary adjustments in real time,” said Dr. Benjamin Movsas, Chair of Radiation Oncology at the Henry Ford Cancer Institute, part of Henry Ford Health System. “This precision radiation enables us to target our therapy to each and every patient individually. I believe this is going to change how we use radiation to treat cancer.”

Of particular interest to the clinicians at Henry Ford Health System are the MRIdian Linac system’s on-table adaptive capabilities, which include the ability to reshape the radiation to match changes in the patient’s anatomy between treatments.

“The start of the MRIdian Linac clinical program at Henry Ford is transformative for cancer patients,” said Chris Raanes, president and CEO of ViewRay. “Henry Ford is nationally recognized for its clinical excellence and innovative cancer treatments, and we are delighted to partner with them in establishing what we hope and expect will become a new standard of cancer care.”
