Treating the Brain Without Surgery
The Gamma Knife is not really a knife, but the newest and most advanced form of stereotactic radiosurgery (a type of radiation therapy), says radiation oncologist Clinton Leinweber, D.O., of Lehigh Valley Hospital and Health Network. It uses computer imaging to identify an exact point in the brain and then sends hundreds of precisely targeted beams of gamma radiation to that point. The equipment is controlled by three highly educated specialists—a radiation oncologist, neuro-surgeon and radiation physicist.
“The Gamma Knife can treat tumors, blood vessel malformations and other abnormalities in even the most difficult-to-reach areas,” Leinweber says. “It is so precise that it delivers high-dose radiation without affecting nearby healthy areas, and it can correct some disorders that conventional surgery cannot. The patient has no incision, no pain and no surgical risks, and often can go home the same day.”
