摘　　要：目的:改进和完善加速器物理特性质量控制工作,以实现提高肿瘤局部控制率,减少正常组织并发症的发生。方法:使用Daily QA3晨检仪、二维电离室矩阵Mapcheck、DOSE1、FC65-G指形电离室、固体水、三维水箱及胶片等工具,对医用加速器的物理特性进行质量控制监测。结果:通过对持续改进医用加速器物理特性的质量控制工作,使得输出量误差均在3%以内,有效监测出因部件老化而引起的物理特性的改变。结论:医用加速器物理特性质量控制工作持续改进后,可规范和便捷地完成质量保证(QA)工作,并可认识和评估放射治疗中的风险,以防止或控制潜在隐患,有效保证放射治疗的安全性和准确性。Objective： To improve quality control of physical characteristics of medical accelerator for improving the tumor control rate and reducing the complications. Methods： Use Nuclear company＇s Daily QA5 morning check meter, two-dimensional matrix Mapcheck ionization chamber; IBA company DOSE1, FC65-G refers to monitor the quality control of physical characteristics of medical accelerator. Results： Through the continuous improvement of medical accelerator physics quality control, the output error is within 5%, and monitored the changes caused by burn-in. Conclusion： After continuous improvement, it can finish the quality control instantly, and recognizeand evaluate the risk in radiation therapy, and prevent or control the potential risks in advance, effectively guarantee the accuracy of radiotherapy.
