摘要
体表光学图像引导放疗系统(SGRT)是一套采用光学跟踪捕获患者的体表信息,记录和纠正患者分次间、分次内的摆位误差,以提高放疗精度的零辐射图像引导系统。为确保患者的治疗安全,必须对体表光学图像引导放疗系统采取必要的质量控制措施,因此,国家癌症中心/国家肿瘤质控中心组织专家制定了本指南。指南内容涉及:SGRT的定义和基本原理;SGRT的配准算法;SGRT的测量方法和类别;SGRT的质控要求;SGRT的放疗规范。
Surface-guided radiation therapy(SGRT)is a zero-radiation image-guided system that uses optical tracking to capture the surface information,record and correct the setup errors between and within fractions,and improve the accuracy of radiotherapy of patients.To ensure the safety of patient treatment,necessary quality control measures must be taken for SGRT.Consequently,National Cancer Center/National Cancer Quality Control Center organized experts to formulate the guideline.The guideline covers the following topics:the definition and basic principles of SGRT;the registration algorithm of SGRT;the measurement methods and categories of SGRT;the quality control requirements of SGRT;and the radiotherapy specification of SGRT.
