Stereotactic irradiation is a precise method for the delivery of focused radiation beams to small intracranial targets. Treatment can be administered in single or multiple fractions (radiosurgery or stereotactic radiotherapy, respectively). The technology has evolved rapidly because of advances in both hardware and software design. Clinical indications are unfolding through the prospective trial mechanism.
立体定向放射治疗是一种将聚焦辐射束精确输送至颅内小靶点的方法。治疗可单次或多次进行（分别为放射外科或立体定向放射治疗）。由于硬件和软件设计的进步，该技术发展迅速。临床适应症正通过前瞻性试验机制逐步显现。
