摘　　要：螺旋断层治疗(Helical Tomotherapy,HT)作为新型调强放射治疗技术(IMRT),其照射方式采用独特的扇形束形式,将现代螺旋CT和直线加速器进行有机整合以实现螺旋断层调强治疗。由于该系统功能复杂,且具有高度集成和自动化特性,监测其运行稳定性和可靠性并不断给予完善、简化其质控流程已成为HT系统质量保证的重要组成部分。本研究通过对前五年该系统质量控制(QC)结果的分析,结合新型质控设备的初步应用,总结其QA的规范化实施并探讨其模式的转变可能。Helical tomotherapy （HT）, as a new IMRT technology, utilizes a fan beam of radiation for treatment. It combines the main characteristics of a modern CT scanner and a linear accelerator to achieve the function of helical tomotherapy. Due to the complexity of the system with a highly integrated and automated features, monitoring its operation, continuing to improve the stability and reliability, and simplifying its quality control procedures has become an important part of quality assurance （QA） for HT. Based on the results of afi ve-year quality control （QC） program, and the initial application of new QA equipment, this study wil summarize the standardization mode of its QA and explore the changes of QA mode.
