摘　　要：立体定向放射治疗(SRT)具有单次照射剂量大、分割次数少、边缘剂量下降快的特点,是治疗脑转移瘤的重要手段。目前基于直线加速器开展的脑转移瘤立体定向放射外科或SRT技术较伽马刀和射波刀经济适用、性价比更高,临床应用更广泛。本指南以已发布的国内外相关标准为依据,聚焦于基于直线加速器开展的SRT技术在临床实践工作所涉及的各个环节,以期帮助国内放疗单位正确安全地运用SRT技术。Stereotactic radiotherapy(SRT)has the characteristics of large irradiation dose per fraction,few fraction sessions and sharp dose falloff out of the target volume,which is an important method to treat brain metastases.At present,stereotactic radiosurgery(SRS)/SRT technology for brain metastases based on linac is more economical and cost-effective than Gamma Knife and Cyberknife,and has more extensive clinical applications.Based on the published domestic and international standards,this guideline mainly focuses on all aspects involved in the clinical practice of stereotactic radiotherapy technology based on linac,and helps domestic radiotherapy institutions to correctly and safely carry out SRT technology.
