立体定向放射神经外科的定义是利用各种放射技术对颅内小型靶区 (病变 )进行三维立体定向放射辐照 ,它的目的是在将病变周围正常组织吸收的放射线剂量减至最小的同时 ,高精度地将大剂量的放射线一次性地传递给靶区 ,使之产生局灶性破坏而达到治疗疾病的目的。用于放射外科的最 Stereotactic radiosurgery is defined as the use of various radiological techniques for three-dimensional stereotactic radiation irradiation of small intracranial targets (lesions). The purpose of this procedure is to minimize the dose of radiation absorbed by normal tissues surrounding the lesion, High-precision high-dose radiation delivered to the target area once and for all, resulting in focal destruction and achieve the purpose of treatment of disease.
