The Paradigm Shift Continues

The first and only radiotherapy system to offer robotic precision, the CyberKnife® System continues to reshape treatments and greatly expand versatility. A proven alternative to surgical intervention and conventional radiation therapy, the CyberKnife System differentiates from other radiation delivery devices by having a linear accelerator mounted on a robotic arm. This provides more flexibility and freedom of motion in how the radiation beams are delivered. The CyberKnife’s integrated X-ray imagers provide continual image guidance and real-time tracking capabilities which ensure the radiotherapy treatment is highly accurate and precise. New innovations dramatically speed treatments and greatly expand versatility to cover the full range of indications.


A Unique Approach to Robotic Radiosurgery and Stereotactic Body Radiotherapy

The CyberKnife System is designed for robotic radiosurgery and stereotactic body radiotherapy. Its precise tumor tracking abilities enable delivery of high doses of radiation in only a few fractions. The CyberKnife System is the only system with the proven ability to delivery SRS and SBRT while tracking and automatically correcting for motion. This gives both clinicians and patients confidence that the CyberKnife System is delivering the maximum dose to the tumor while minimizing healthy tissue exposure — minimizing side effects and maximizing patient comfort, without sacrificing efficiency or effectiveness.

Robotic Radiosurgery and Stereotactic Body Radiotherapy

Deliver robotic radiosurgery and stereotactic body radiotherapy anywhere in the body with true robotic precision. The CyberKnife M6 System, world’s most advanced radiotherapy robot, delivers treatments in an industry-exclusive 3D workspace, subdivided into anatomy-specific paths. The CyberKnife System is capable of delivering thousands of non-coplanar or coplanar beam angles to either stationary targets or targets in motion.


Synchrony®: Real-time, dynamic motion synchronization

Precisely synchronize treatment delivery with patient and tumor motion in real time. Synchrony, the industry’s only true motion synchronization technology, combines fully integrated imaging and indication-specific tracking applications to enable constant intra-fraction position tracking and automatic 6D motion synchronization. This gives you the confidence to aggressively attack tumors while minimizing dose to healthy tissue, thus minimizing side effects.


Robotic multileaf collimator

Improve clinician and patient experiences with faster treatment times. The CyberKnife M6 System with InCise MLC gives you unprecedented ability to treat larger targets with fewer beams, in less time.


Efficient stereotactic treatment planning

Leverage powerful features including multimodality image fusion with deformable image registration, industry-leading Autosegmentation™, and accelerate both treatment planning and treatment delivery with the next-generation CyberKnife VOLO™ Optimizer. Streamlined re-treatment planning utilizes the industry leading PreciseRTX® Retreatment Option.


Fully integrated patient data management

Empower your team to connect, share, analyze and leverage data to unlock collaboration opportunities, enable smarter treatment planning and drive more efficient workflows across your practice. The iDMS® Data Management System connects all Accuray treatment planning and delivery systems, providing a single, integrated control center for all patient and system data.
