How is the CyberKnife® System Different?

Precision Through Robotic Architecture

The CyberKnife System uses a robot that bends and moves around the patient. It can approach the target from hundreds of unique angles, significantly expanding the possible positions from which radiation beams can be delivered. The more degrees of freedom – the angles and points in space from which to approach the tumor – the better the radiation beams can be sculpted to avoid critical anatomical structures.

Precision Through Motion Management

Many things happen from the time a patient has been set up on the treatment couch and radiation is delivered. The patient could change their position. The patient could cough. Muscles tense and relax. Fluids and gasses displace internal organs. The patient breathes. The CyberKnife System is designed to automatically accommodate all forms of patient and tumor motion, even while the treatment is being delivered. With its motion management technology, the CyberKnife System enables smaller treatment margins around the tumor, minimizing the amount of healthy tissue exposed to high-dose radiation.

• CyberKnife Motion Management

The CyberKnife System uses advanced technologies to track tumors anywhere in the body, while its unique robotic design keeps the radiation on target even while the tumor moves. Before delivering the radiation beam, the CyberKnife System verifies the exact tumor position and adjusts the robot to precisely target the tumor. This ensures radiation is delivered to where the tumor is, not to where it was moments before.

• Synchrony® Respiratory Tracking System

The Synchrony Respiratory Tracking System is the only clinically proven system that uses continual image guidance to synchronize the movement of the radiation beam with the movement of the target while the patient breathes normally. The Synchrony Respiratory Tracking System enables patients to breathe naturally throughout the treatment. This highly sophisticated technology locks the robot motion on to the target so that the robot follows the patient's every breath. Besides delivering the radiation with greater precision, the CyberKnife System makes treatment more comfortable for patients who may have compromised lung function by eliminating the need for breath-holding or chest immobilization.
