The revolutionary CyberKnife treatment technology is not new; the CyberKnife System has more than two decades of clinical proof and has helped thousands of patients with various brain tumors and metastases. The CyberKnife System is routinely used to treat conditions in the brain including, but not limited to, benign and malignant primary tumors, brain metastases, trigeminal neuralgia, acoustic neuromas and arteriovenous malformations (AVMs). CyberKnife radiosurgery is even used to treat complicated neurosurgical cases, while maximally sparing healthy brain tissues involved in important functions such as motor control, touching, hearing and vision.
