MRI-Guided Radiation Therapy System (ViewRay) for Cancer treatment receives FDA 510(k) approval

The MRI-Guided Radiation Therapy System, from ViewRay, has received US FDA 510(k) premarket notification clearance. The system features a combination of radiotherapy delivery and simultaneous magnetic resonance imaging (MRI) for the treatment of cancer and is designed to capture soft-tissue images continuously during treatment, so that clinicians are able to see where the actual radiation dose is being delivered and adapt to changes in the patient's anatomy. ViewRay's treatment planning and delivery software received 510(k) premarket notification clearance in 2011.
