New tools use robotics
to treat lung cancer.
Sunnyvale, Calif. Accuray Incorporated, a global leader in the field of robotic radiosurgery, today introduced three new products designed to improve the way lung cancer is treated. These products Xsight Lung Tracking System, Xchange Robotic Collimator Changer and 4D Treatment Optimization and Planning System combine with the Accuray CyberKnife Robotic Radiosurgery System to offer a non-invasive, fiducial-free lung cancer treatment option that eliminates the risk of complications common with the implantation of markers or fiducials. Moreover, the products can shorten treatment times through treatment planning optimization and reduced treatment delivery interruptions.
These products will be 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.

The CyberKnife System
Lung cancer radiosurgery using the CyberKnife System is growing, with more than a 130 percent increase in the number of patients treated in the last year alone. The Xsight Lung Tracking System offers a significant technological breakthrough which further enhances the CyberKnife Systems position to become the standard of care for lung radiosurgery, said Euan S. Thomson, Ph.D., president and chief executive officer of Accuray. With the first and only non-invasive radiosurgical means to precisely target and treat tumors, Accuray is breaking down barriers for patients who may not otherwise be able to receive treatment.
The Xsight Lung Tracking System uses sophisticated image processing and registration techniques to directly lock onto and track the tumor throughout the treatment. It works seamlessly with Accurays Synchrony Respiratory Tracking System to track, detect and correct for tumor and patient movement, allowing patients to breathe normally without the need for gating or breath holding techniques. Xsight Lungs radiosurgery accuracy may eliminate the need for the invasive placement or tracking of radiographic markers or fiducials reducing the risk inherent to traditional treatment methods.
Designed to offer a non-invasive, more comfortable alternative for patients, the Xsight Lung Tracking System maintains the precision and accuracy required for radiosurgery treatments. Published data(1) states that there is a risk of pneumothorax when fiducials are used to mark lung tumors. By using non-invasive means to precisely target lung tumors, oncologists will be able to more quickly and effectively treat patients, including ones who are now considered to be medically inoperable.
