Scientific Presentations at 2009 ASTRO Meeting Highlight RapidArc® Radiotherapy Technology from Varian Medical Systems

Chicago, IL — November 10, 2009 — Clinicians using RapidArc® radiotherapy technology for fast, precise, non-invasive cancer treatments have found that they are able to substantially reduce scatter dose to surrounding healthy tissues, according to several presentations and posters presented this week at the annual meeting of the American Society for Radiation Oncology (ASTRO) in Chicago. With RapidArc, doctors were able to quickly administer image-guided radiotherapy or radiosurgery treatments using fewer monitor units, which translates to less total body irradiation during treatment. In addition, a number of planning studies documented the clinical advantages of RapidArc over other forms of intensity-modulated radiotherapy (IMRT).

ASTRO is the largest association of radiation oncology professionals in the world, with 10,000 members, including radiation oncologists, radiation oncology nurses, medical physicists, radiation therapists, dosimetrists and biologists. The 2009 meeting was held in Chicago, Illinois, from November 1-5.
