Gamma Knife vs. CyberKnife

As one of the most experienced Gamma Knife treatment teams at one of the most active Gamma Knife centers in the U.S., we at Wake Forest Baptist know that Gamma Knife is the leader in noninvasive brain surgery. Its success has been documented for 5 decades, with more than 350,000 cases treated worldwide, providing data for more than 2,000 articles in medical publications.

Other types of radiosurgery, such as the CyberKnife® Robotic Radiosurgery System, may claim to be as effective and efficient. But it isn’t true.

Gamma Knife has raised the bar for all other types of radiosurgery, including CyberKnife. For example: 


 Gamma Knife


Exclusively for brain surgery

Not exclusively for brain surgery

Better than 0.3 mm accurate at targeting radiationWithin 1.0 mm accurate at targeting radiation

(Cyberknife causes 2–6 times more radiation exposure outside target area than Gamma Knife treatment.)  
Uses head frame to prevent head movement and precisely sync images from MRIs or CT scans with radiation delivery

Uses plastic face mask to minimize head movement and closely sync images from MRIs or CT scans with radiation delivery

(Treatment is less accurate because positioning is done visually, not by using a head frame.)

Target position is confirmed 10 times per second.

Target position is confirmed once every 10 seconds. 
Treatment completed in 1 session.Treatment can take multiple sessions, over several days.
