The FDA granted ViewRay an approval known as a “510(k) clearance” to market the MRIdian Linac system. Linac is a nickname for a linear accelerator, an integral part of the MRIdian system that produces the radiation that kills the cancer.
The first generation MRIdian was FDA cleared in 2012 and uses the same MRI technology but delivers radiation through cobalt technology. “With the Linac, we can now hit the cancer just as hard with powerful doses of radiation but in shorter periods of time,” said Chris A. Raanes, president and chief executive officer of ViewRay in a recent interview. “Just as a surgeon sees what he or she is cutting on the operating table, the radiation oncologist can see that same level of precision using the MRIdian system.”
