FDA approves Edge Radiosurgery Suite (Varian Medical Systems) for Radiation Therapy

The FDA has given 510(k) clearance for Varian Medical System's Edge Radiosurgery Suite, a new dedicated system for performing advanced Radiation Therapy using new real-time tumor tracking and motion management technologies. The system includes an integrated six degrees of freedom couch that provides the accuracy, precision, and flexibility needed to position patients. It also allows expanded use of fluoroscopy and 4-D cone-beam CT�imaging techniques that show motion over time, to better compensate for tumor motion during treatment, as well as the Calypso system, which utilizes transponders that are implanted in or around a tumor, or placed on the surface of the body and monitored to track motion during treatment.
