History of CyberKnife

CyberKnife® Robotic Radiosurgery System

A new paradigm in full body radiosurgery, the CyberKnife System leads the field with groundbreaking technology.

The CyberKnife System is the world’s first and only radiosurgery system designed to treat tumors anywhere in the body with sub-millimeter accuracy. Using image guidance technology and computer controlled robotics, the CyberKnife System is designed to continually track, detect and correct for tumor and patient movement throughout the treatment. Because of its extreme precision, the CyberKnife System does not require invasive head or body frames to stabilize patient movement, vastly increasing the system’s flexibility.

Continual Image Guidance Throughout the Treatment

Many tumors, even when immobilized, have proven to shift during treatment delivery. Using advanced robotic technology and continual image guidance, the CyberKnife System delivers unprecedented targeting accuracy with the unique ability to automatically correct for intra-fraction target motion – without interrupting the treatment or having to reposition the patient.

Automated Non-Coplanar Treatment Delivery

Unconstrained by the clockwise / counter-clockwise gantry rotations of conventional radiotherapy systems, the robotic mobility of the CyberKnife System delivers automated non-coplanar treatments without clinician intervention or treatment interruption. This capability efficiently enables unrivaled conformality and dose gradient for treating even the most complex targets.

Beams Move in Real-Time with 3D Respiratory Tumor Motion

Without the limitations of conventional respiratory gating and breath-holding techniques, the CyberKnife System delivers beams that move precisely with tumor motion throughout the respiratory cycle. By dramatically reducing the planning margins to only that which are clinically relevant, the CyberKnife System has proven to provide unparalleled healthy tissue preservation.
