CyberKnife® Stereotactic Radiosurgery

Cyberknife® stereotactic radiosurgery is a high-tech, non-invasive treatment alternative to traditional surgery. It uses highly focused beams of radiation to treat cancerous and noncancerous tumors, as well as conditions such as AVMs, trigeminal neuralgia, meningiomas, schwannomas and pituitary adenomas.


CyberKnife treatment is a pain-free option that doesn’t involve any incisions. It can be used in conjunction with traditional surgery and is also an option for patients who have inoperable or surgically complex tumors. When lesions are adjacent to healthy tissue, Cyberknife allows doctors to precisely customize the treatment to avoid exposing the healthy tissue to excessive radiation.

The CyberKnife can also precisely track moving targets, such as areas in your chest and abdomen that move when your breathe. As a result, it can be used to treat lung cancer, as well as cancers of the brain, liver, pancreas, spine or pelvis. The technique’s accuracy is achieved with an advanced X-ray guidance system located within the same housing that delivers the high-dose radiation.

What to Expect

Patients lie on a table while a six-jointed robotic arm moves around them, delivering radiation from several different angles. The radiation passes through healthy tissue, leaving it unharmed, while converging at one small point – like a magnifying glass. 

Because CyberKnife radiosurgery treatment is so accurate, it can deliver a more potent beam of radiation – requiring only 1 to 5 outpatient sessions that last between 30 minutes and 2 hours each.
