What is a Gamma Knife?
|
In our daily life, everyone is very familiar with tumors. Tumors are divided into benign and malignant tumors. In general, many of them are benign, so you just need to pay attention to observation. If a malignant tumor is found, many people will choose gamma knife treatment. Compared with traditional treatment methods, gamma knife has fewer side effects and better treatment effects. Question 1: What people often call the Kernel is actually the Gamma Knife, but the Kernel is a wrong name. The correct name should be Gamma Knife or Gamma Knife. The gamma knife is not a real scalpel. Its full name is: Gamma ray stereotactic therapy system. It is a hemispherical helmet covered with collimators, which can emit 201 high-dose cobalt-60 ion rays - gamma rays. It is precisely located at a certain part of the brain through modern imaging technologies such as CT and MRI, which we call the "target." Gamma Knife is gamma ray. Question 2 : Gamma Knife: Many people would think that this is a surgical technique just by hearing the term, but it is not. Gamma Knife is a type of radiotherapy. The treatment principle is the same as that of radiotherapy, except that Gamma Knife uses gamma rays while other radiotherapy uses X-rays. Since the dose distribution curve of the gamma knife is a fit after high dose superposition, the dose distribution is highly concentrated and has the characteristics of a knife, it is called the gamma knife. Question 3 : Its positioning is extremely accurate, with the error often less than 0.5 mm; the dose gradient of each gamma ray is extremely large, causing almost no damage to tissues. But 201 rays coming together from different locations can fatally destroy the target tissue. It gets its name because it functions like a scalpel, and the operation only takes a few minutes to tens of minutes. Tens of thousands of people around the world have received treatment. Gamma Knife has the advantages of being non-invasive, not requiring general anesthesia, not requiring craniotomy, causing no bleeding, and causing no intracranial infection. The disadvantage is that the treatment is relatively expensive. Classification question 4 is a very advanced radiotherapy device for tumor treatment. It irradiates the human body with many very thin beams of gamma rays from different angles and directions, and makes them converge at one point to form a focus. There are "Gamma Knives" for the head and "Gamma Knives" for the body. The Free GS type rotating head "Gamma Knife" represents the latest level of current head "Gamma Knife". "Gamma Knife" is divided into "Gamma Knife" for the head and "Gamma Knife" for the body. There are two types of head "Gamma Knife": static "Gamma Knife" and rotary "Gamma Knife". The static "Gamma Knife" installs multiple cobalt sources in a spherical helmet to focus them on a certain point inside the skull. The rotary "Gamma Knife" is improved on the basis of the static type, has many advantages, and is a Chinese patent. |
