The Gamma Knife is an advanced radiation treatment for adults and children with small to medium brain tumors, abnormal blood vessel formations called arteriovenous malformations, epilepsy, trigeminal neuralgia, a nerve condition that causes chronic pain, and other neurological conditions. Despite its name, the Gamma Knife isn't a knife What is a Gamma Knife? The Gamma Knife is not a knife in the conventional sense, but uses a focused array of intersecting beams of gamma radiation (see the picture to the right) to treat lesions within the brain. Gamma Knife® is a non-invasive stereotactic radiosurgery instrument that involves no scalpel or incision – it’s not a knife at all. Instead, the Gamma Knife® uses up to 192 precisely focused beams of radiation to control malignant and nonmalignant tumors, as well as vascular and functional disorders in the brain, without harming surrounding healthy tissue. radiation. Instead, the Gamma Knife delivers a high dose of radiation in a single session to a stereotactically defined target by converging multiple beams of ionizing radiation.
The Gamma Knife is an advanced radiation treatment for adults and children with small to medium brain tumors, abnormal blood vessel formations called arteriovenous malformations, epilepsy, trigeminal neuralgia, a nerve condition that causes chronic pain, and other neurological conditions. … Gamma Knife. Gamma Knife® is a radiation therapy that uses computerized treatment planning software to help physicians locate and irradiate small targets within the head and brain with very high precision. The treatment delivers intense radiation doses to … Gamma Knife radiosurgery is one of the most precise, powerful, and proven treatments for brain disorders. This painless procedure uses hundreds of highly focused radiation beams to target tumors and lesions within the brain.

Gamma knife surgery involves focusing small, highly precise doses of radiation into the brain. This shrinks small brain tumors or blocks abnormal blood vessels and nerves that cause pain or seizures. Gamma Knife surgery (GKS) is a safe, effective and non-invasive procedure that uses radiation to treat conditions in and around the brain. It is sometimes used as a replacement for conventional surgery, but at other times it may be effective in situations where there is no conventional surgical alternative available. With the Gamma Knife device, a finely focused, high dose of radiation is delivered from 192 individual radiation sources that are positioned to precisely converge on the tumor area.
Gamma knife is not really a knife; it is a beam of highly focused gamma rays, to precisely cut or

It delivers a single, large dose of radiation only to the tumor, or target, without affecting surrounding healthy tissue in the brain. It was developed by researchers in Sweden nearly 30 years Only one treatment is needed. It usually takes just one 10-minute to 70-minute procedure to deliver radiation with the gamma knife. It works. There is evidence that treatment of certain malignant Radiosurgery is performed by delivering a high dose of ionizing radiation in a single treatment session using multiple beams precisely focused at the target inside the brain. Several reports have documented the efficacy of Gamma Knife®‚ stereotactic radiosurgery for trigeminal neuralgia .
