For brain tumors, the only approved stereotactic radiosurgery system is Gamma Knife surgery. Gamma Knife surgery offers a guaranteed precision that can't be achieved with Cyberknife surgery.
With Gamma Knife surgery the head is held stationary, and radiation is directed toward the brain from all angles simultaneously. Contrast that with Cyberknife surgery that requires multiple X-rays of the brain, and where the arm of the machine is in constant motion.
Gamma Knife surgery requires only a single session of treatment rather than multiple visits. It makes sense to look to Gamma Knife surgery for effective, precise treatment of brain tumors.
