The CyberKnife combines two technologies: a lightweight radiation delivery system mounted on a multi-jointed robotic arm, and an image guidance system that compensates for slight human movements during the treatment.
The CyberKnife® System from Accuray is the world's most accurate radiosurgery instrument. It establishes a new gold standard in radiosurgery by precisely ablating tumors and other lesions anywhere in the body, with submillimeter Total Clinical Accuracy*.
The CyberKnife System gives patients new hope for treating tumors previously diagnosed as inoperable or untreatable.
