what is gamma knife

Gamma Knife is a type of radiosurgery that uses very precise beams of gamma rays to treat areas of disease or growth, most often in the brain. Despite its name, it is not a knife and does not involve any incisions. The Gamma Knife delivers highly focused radiation to its target, while causing little or no damage to surrounding tissue. It is used to treat conditions such as brain tumors, arteriovenous malformations, trigeminal neuralgia, and other neurological conditions. The treatment is usually performed in a single day and is often safer and less invasive than standard brain surgery
