New CyberKnife Technologies Improve Treatment Times, Optimize Planning Objectives and Offer Increased Clinical Flexibility in Radiation Delivery

SUNNYVALE, Calif., Oct. 29 /PRNewswire-FirstCall/ -- Accuray Incorporated (Nasdaq: ARAY), a global leader in the field of radiosurgery, announced today four new products designed to improve treatment times, optimize treatment planning objectives and offer greater clinical flexibility in radiation delivery. These products are being launched at the 49th Annual Meeting of the American Society for Therapeutic Radiology and Oncology (ASTRO) in Los Angeles.

Iris(TM) Variable Aperture Collimator

In radiosurgery, clinicians can define the amount, or dose, of radiation delivered during treatment using a collimator -- a metal radiation blocking device with an opening that dictates the shape and size of the radiation beam. In the past, when clinicians wanted to use multiple collimators to vary the size and shape of their radiation beam it required they manually switch out collimators in the middle of treatment.

With the launch of the CyberKnife System's Xchange(TM) Robotic Collimator Changer at ASTRO 2006, the process of changing collimators became automated, eliminating the need to re-enter the treatment room, which minimizes related treatment delays.

Now the process for using multiple collimators has become even more streamlined with the introduction of the Iris(TM) Variable Aperture Collimator, which no longer requires the removal of a collimator because it can automatically alter the size of its opening to let radiation beams of 12 discreet sizes pass through.
