Varian Medical Systems Introduces a Trilogy® Accelerator With Gated RapidArc® and Advanced Motion Management

PALO ALTO, Calif., April 14 /PRNewswire-FirstCall/ -- Varian Medical Systems (NYSE: VAR) has added advanced motion management capabilities including gated RapidArc to its Trilogy platform for treating cancer with targeted radiotherapy. A set of sophisticated new tools now enables clinicians to monitor and adjust for tumor motion during treatment, and to utilize respiratory gating during a RapidArc® treatment.

"Extensive research and development into motion management systems has culminated in powerful new capabilities that will be standard on the new Trilogy accelerators and available as an upgrade on our large installed base of Trilogy and Clinac iX machines," said Dow Wilson, president of Varian's Oncology Systems business. "Our Clinac iX and Trilogy accelerators together with our new TrueBeam platform (see accompanying press release) can now offer clinics an unmatched combination of motion management, speed, and versatility."

Gated RapidArc® radiotherapy makes it possible to monitor patient breathing and compensate for tumor motion while quickly delivering dose during a continuous rotation around the patient. This development enables the use of RapidArc to target lung tumors with greater precision by "gating" the beam—turning it on and off—in response to tumor motion.
