SUNNYVALE, Calif. - Accuray Incorporated (Nasdaq: ARAY), a global leader in the field of radiosurgery, announced today the introduction of the CyberKnife® VSI™ System, the latest addition to the CyberKnife product family. The new CyberKnife VSI, which stands for versatile, simple and intelligent, is designed to broaden physicians' range of options from radiosurgery to also include conventionally fractionated Robotic IMRT. This enables them to customize their care around the unique needs of each patient, thereby expanding the population of patients that can benefit from the System's unparalleled precision.

Over the years the CyberKnife® Robotic Radiosurgery System has established itself as a leader in full body radiosurgery. The CyberKnife VSI System leverages the benefits of radiosurgery -such as high accuracy and excellent healthy tissue sparing - and extends them to enable delivery of high-precision radiation therapy. This new CyberKnife capability gives clinicians greater versatility by providing additional options for them to consider when determining the optimal course of treatment for each patient.

CyberKnife VSI System features product enhancements including a world-class 1,000 MU/minute X-band linear accelerator, advanced visualization capabilities, automated segmentation capabilities and logical workflow designed to enhance the physician and patient experience.
With several hundred peer-reviewed publications and a rapidly increasing number of treated patients, the growing community of CyberKnife users are discovering more applications that can benefit from the clinical flexibility and technological edge the CyberKnife System provides.

Clinical Flexibility

From a radiosurgical approach to a conventionally fractionated Robotic IMRT™ approach, the CyberKnife VSI System provides the clinician the flexibility to choose the best course of care based on individual patient needs. The CyberKnife VSI System supports this full spectrum of fractionation schemes by enabling simple and convenient treatments that can be completed in routine clinical practice. Treatment times are expected to be comparable to IMRT delivered using a conventional linear accelerator.

Technological Edge

Managing target motion presents one of the most significant challenges in radiation treatment delivery. Unlike other radiation delivery systems, the CyberKnife System offers motion management capabilities that adapt treatment delivery for target motion in real-time using continual image guidance and robotic mobility.
