Gamma knife is not a real scalpel, but a very advanced radiation therapy equipment, its full name: Gamma ray stereotactic therapy system. It shines many very thin beams of gamma rays through the body from different angles and directions, and causes them all to converge at one point to form a focal point. As the dose of each beam is very small, basically no damage to the human tissue it crosses, as long as the focus is aimed at the lesion, it can be as accurate as a scalpel to destroy the lesion at once, to achieve the magical effect of no trauma, no bleeding, no infection, no pain, rapid, safe and reliable.
The treatment principle of Gamma Knife is similar to the focusing process of a magnifying glass. Put the magnifying glass in the sunlight, the magnifying glass below will form a dazzling light class that is the focus. Outside the focal point, the person feels as normal, but at the focal point there is a high level of heat, enough to cause some objects to ignite. Of course, to focus in the human body, with the sun’s rays is not possible, but must be used with penetrating high-energy rays such as gamma rays; at the same time, to make the gamma rays focus is not as simple as a magnifying glass focus, but a comprehensive use of nuclear physics, computers, biological radiation, electromechanical and a series of modern technologies to achieve. Therefore, the gamma knife is the product of modern high technology at the end of the twentieth century, as a new non-invasive treatment, it is a revolutionary breakthrough in the history of medical treatment.
