Accuray CyberKnife (family)
Robot-mounted 6 MV compact linear accelerator on a KUKA industrial robotic arm — delivers non-isocentric beams to a moving target using real-time image-guided tracking (Synchrony for respiratory motion, Xsight Spine for bony anatomy, fiducial-based for soft tissue). Primary clinical niche: spine SBRT, lung SBRT with motion, prostate SBRT, and extracranial SRS.
Variants
- CyberKnife G3 / G4 — earlier generations (largely displaced)
- CyberKnife M6 — MLC-equipped, current-generation
Shared platform characteristics
- 6 MV X-band linac on robotic arm
- Orthogonal x-ray imaging system for target tracking
- Synchrony respiratory motion tracking + Xsight Spine / Lung / fiducial tracking modes
- Multi-hour treatment time traditionally (shorter with MLC)
