How CyberKnife® Works

CyberKnife® is one of the most advanced and effective stereotactic radiosurgery technologies. Stereotactic radiosurgery is a method of controlling or destroying tumors by aiming beams of radiation at the tumor from multiple directions.

How does CyberKnife work?

CyberKnife uses computers and imaging tools to pinpoint the exact location of a tumor. A robotic arm points a linear accelerator, which produces very high levels of radiation, directly at the tumor from more than 1,400 different angles.

The robotic arm works together with multiple X-ray cameras and powerful software to track the precise location of the tumor, even if it moves as a patient breathes or as other processes take place within the body. The robotic arm provides unparalleled flexibility to aim high-powered radiation beams even to difficult locations within the body with laser-like accuracy.

CyberKnife technology also focuses radiation beams precisely on the tumor—and not on any surrounding healthy tissue.

Synchrony® Respiratory Tracking System

The Synchrony Respiratory Tracking System tracks breathing in real time. It coordinates how the CyberKnife delivers radiation beams with the movement of the tumor as you breathe. This allows CyberKnife to target tumors with great accuracy anywhere in the body. In addition, you do not have to hold your breath during the procedure.
