In 1951, Professor Leksell of Sweden first proposed the concept of radiosurgery, envisioning the use of stereotactic technology, using high doses of high-energy proton beams to destroy the target tissue at once, to achieve the general efficacy of surgical treatment, and named this treatment method stereotactic radiosurgery ” Stereotacfic Radiosurgery”. Accordingly, radiosurgery for the nervous system is also called Stereotactic Radioneurosurgery, i.e., according to the principle of stereotactic, the normal or diseased tissues in the skull are selectively identified as targets, and a single high-dose narrow beam ionizing radiation is used to precisely focus on the target to produce focal destruction and achieve the purpose of treatment. The discipline of radiation therapy. Since the radiation has the distribution characteristics of high converging dose in the target area and rapidly decreasing dose around it, the tissues around the target area are almost not damaged by the radiation, and its destruction of the target area is similar to scalpel-like excision, so it is imaginatively called: “knife”. According to the use of different radiation sources, static or dynamic irradiation differences, and the head of the commonly used stereotactic radiosurgery system referred to as “gamma knife” and “X-knife”. There is a fundamental difference between stereotactic radiation neurosurgery and traditional radiotherapy, which uses the different sensitivity of tumor tissue and normal tissue to radiation (Radiosensitivity) to treat disease, and the normal tissue is irradiated with larger doses at the same time, so the accuracy of traditional radiation therapy equipment is far from being able to adapt to the needs of stereotactic radiation neurosurgery. Therefore, the accuracy of traditional radiation therapy equipment is far from being able to meet the needs of stereotactic radiosurgery. Stereotactic radiation neurosurgery is significantly different from general neurosurgery. Stereotactic radiation neurosurgery can avoid the risk of intraoperative and postoperative bleeding, infection and damage to important intracranial structures associated with traditional neurosurgical open cranial surgery, especially for deep brain lesions and multiple lesions, becoming a favorable supplement to general neurosurgery and greatly expanding the treatment scope of neurosurgery, improving the quality of survival of treated patients to a certain extent. It has greatly expanded the scope of neurosurgery and improved the quality of life of patients treated.
