The CyberKnife® Technology

The CyberKnife system sets the standard for precision in radiation delivery

CyberKnife system

The CyberKnife system offers a non-surgical solution for treating both cancerous and non-cancerous tumors and conditions requiring radiation therapy. It can be used on various parts of the body, such as the prostate, lung, brain, spine, head and neck, liver, and kidney, offering an alternative to surgery for inoperable or complex tumors.

CyberKnife Robot

The CyberKnife system stands out as the only complete robotic solution for radiation delivery. Its robotic design combined with real-time imaging allows for delivery of high-dose radiation directly to the tumor with unparalleled precision, using thousands of beam angles. The result is sub-millimeter accuracy in every treatment.

True Robotic Delivery Precision

The CyberKnife system's unique design, featuring a LINAC mounted on a robot, allows for delivery of high-energy radiation from various angles, resulting in greater precision and accuracy. This precision not only reduces the impact on surrounding healthy tissues but also improves the patient's quality of life both during and after treatment.

Real-time motion synchronization

Motion management in radiation therapy is crucial as patients can move or change their position during treatment. The CyberKnife motion adaptive technology is specifically designed to address these issues, allowing for smaller treatment margins around the tumor and thereby reducing exposure of healthy tissue to high-dose radiation.
