摘　　要：CT模拟机为放射治疗计划设计提供患者的解剖学信息,是进行三维计划设计、剂量计算和计划评估的基础。CT模拟机质量控制的目的是保证模拟定位过程的安全与放射治疗靶区及其周围重要器官的精确勾画,以及提供放疗计划剂量计算所需的准确数据。本指南内容主要涵盖了CT模拟机的机械性能、图像质量、定位流程和辐射防护4个方面的质量控制。CT simulator can provide patients'anatomical information for the design of radiotherapy plan.It is the basis for 3D plan design,dose calculation and plan evaluation of radiation therapy.The purpose of the quality control of CT simulator is to ensure the safety of CT simulated positioning process and accurate delineation of the radiotherapy target area and its surrounding vital organs,as well as to provide accurate data required for the dose calculation of radiotherapy plan.This guideline mainly covers four aspects of quality control:mechanical properties,image quality,positioning process and radiation protection.
