Accuray Integrates In-Room 4D Imaging With the CyberKnife Robotic Radiosurgery System

SUNNYVALE, Calif., Nov. 6 (HSMN NewsFeed) -- Accuray Incorporated, a global leader in the field of robotic radiosurgery, today introduced the industry's first solution that combines the power of robotic radiosurgery with either 3D or 4D diagnostic quality computer tomography (CT) scanning in the treatment room. With advanced imaging technology, clinicians can visualize the exact location of the tumor and its surrounding critical structures, immediately prior to treatment, to ensure the radiosurgery procedure delivers the treatment as planned.

Unlike other in-room imaging solutions, the 4D imaging system is designed to ensure clinicians have access to diagnostic quality images and 4D image data in unmatched acquisition time. Radiation therapy solutions have generally relied on slower, lesser quality imaging techniques such as cone beam imaging. In contrast, the Accuray radiosurgery solution offers the option of incorporating a Siemens state-of-the-art SOMATOM® CT system, enabling faster, dynamic, higher resolution, diagnostic quality imaging in the treatment room.

"We have designed the CyberKnife System to be the most accurate frameless robotic radiosurgery system in the world," said Euan S. Thomson, Ph.D., president and chief executive officer of Accuray. "It is a dynamic treatment system that can track tumors throughout the treatment, even as they move with respiration. In evaluating our options for in-room imaging, we selected a high resolution 4D system, the most advanced option available. This collaboration with Siemens has enabled Accuray to bring state-of-the-art 3D and 4D diagnostic quality imaging into the CyberKnife radiosurgery treatment process."

The combination of the CT scanner with the CyberKnife System is made possible by the recent release of the RoboCouch(TM) Patient Positioning System. Once positioned on the robotic couch, the patient undergoes a CT scan, which allows the clinician to quickly verify the treatment plan and the exact location of the tumor and adjacent critical structures. Without moving the patient from the treatment table, the RoboCouch System then transitions the patient from the CT scanner to the CyberKnife System where the patient receives radiosurgery treatment.

The Accuray CyberKnife® Robotic Radiosurgery System and the Siemens Somatom® CT Scanner with sliding gantry are on display in Booth 219 at the American Society for Therapeutic Radiology and Oncology (ASTRO) Annual Meeting at the Pennsylvania Convention Center in Philadelphia, November 5-9.

About the CyberKnife® Robotic Radiosurgery System

The CyberKnife System is the world's first and only radiosurgery system that utilizes intelligent robotics to treat tumors anywhere in the body with sub-millimeter accuracy. The CyberKnife System treats patients in single or staged (typically 2-5) sessions by delivering multiple beams of precisely directed radiation that converge upon the tumor while minimizing injury to surrounding healthy tissue. Image guidance and computer controlled robotics combine to continuously track, detect and correct for tumor and patient movement throughout the treatment. Because of this precision and accuracy, no head or body frame is required.
