The CyberKnife system delivers radiation for brain tumors with sub-millimeter precision (typically less than 1 mm, or under 1 millimeter of targeting error), rather than a 5 mm margin.
Key Precision & Technology Facts
Sub-Millimeter Accuracy: The robotic system maintains targeting precision under 1 mm, allowing safe treatment of lesions close to critical structures like the optic nerve or brainstem.
Tumor Size Detection: Advanced diagnostic imaging (such as MRI) can detect small brain tumors as small as 2 to 5 mm in diameter, though tumors larger than 5 mm are more frequently identified.
Real-Time Motion Tracking: Instead of a rigid metal head frame bolted to the skull, CyberKnife uses real-time image guidance and AI-driven synchronization (such as the Synchrony system) to track skull and tumor movement down to a fraction of a millimeter.
Outpatient Delivery: Treatments are completed in 1 to 5 sessions without surgical incisions, general anesthesia, or hospitalization.
