What is Gamma Knife

Gamma Knife surgery is a treatment for hepatitis B virus, which is mainly divided into head treatment and body treatment. Patients are required to choose a regular hospital for surgery to avoid side effects caused by the surgery. Gamma Knife surgery is a procedure that uses radiation to suppress the hepatitis B virus and remove tumors from the body. Gamma Knife surgery does not cause wounds and does not require anesthesia, but patients with weak bodies cannot undergo Gamma Knife surgery.

Gamma Knife therapy is divided into head Gamma Knife therapy and body Gamma Knife therapy. Gamma knife therapy for the head involves installing multiple cobalt sources in a spherical helmet and focusing them on a certain point in the skull to form a narrow beam of gamma rays with sharp edges. During treatment, a narrow beam of radiation is focused on the lesion to form a localized high-dose area to destroy the lesion. It is mainly used to treat small intracranial tumors and functional diseases. Body Gamma Knife therapy is mainly used to treat various tumors throughout the body.

Scope of application

Gamma Knife[1] is divided into head Gamma Knife and body Gamma Knife. There are two types of gamma knife for head surgery: static gamma knife and rotating gamma knife. The static gamma knife installs multiple cobalt sources in a spherical helmet and focuses them on a certain point inside the skull. The rotating gamma knife is improved on the basis of the static type, has many advantages, and is a Chinese patent.

Gamma knife radiotherapy on the head can non-invasively cure trigeminal neuralgia (trigeminal neuralgia), glioma, meningioma, acoustic neuroma, pituitary tumor, craniopharyngioma, etc.

Body Gamma Knife is mainly used to treat various tumors throughout the body.

1. Benign intracranial tumors such as acoustic neuroma, pituitary tumor and meningioma less than 30 mm;

2. Small and deep intracranial arteriovenous malformations;

3. Some surgeries cannot completely remove benign tumors;

4. Small intracranial metastatic cancer with clear margins;

5. Functional diseases such as Parkinson's disease, epilepsy, and mental illness.

Gamma Knife is suitable for the treatment of lung cancer, liver cancer, pancreatic cancer, adrenal tumors, kidney cancer, mediastinal tumors, retroperitoneal tumors and pelvic tumors. Body Gamma Knife can be used alone for radical treatment of small tumors or combined with a variety of radiotherapy techniques.

Gamma Knife therapy for the body does not require surgery or anesthesia, is non-traumatic, has mild side effects, and does not require hospitalization. Therefore, it is particularly suitable for the treatment of elderly and frail patients who cannot tolerate surgery or patients who refuse surgery due to fear.
