TrueBeam直线加速器影像系统的校准维护

Calibration and Maintenance of TrueBeam Linac Image System

瓦里安直线加速器配置的机器性能检查软件MPC(Machine Performance Check,MPC)检测机器性能全面并检测时间短,能满足临床对直线加速器质量验证需求,目前已被广泛应用到加速器的晨检。为了保证MPC软件测量结果的准确性和稳定性,文章通过对影像系统的机械性能和图像质量校准维护的介绍,使操作人员熟悉影像系统的校准维护,为治疗工作的顺利进行,创造良好的设备环境。

The Machine Performance Check(MPC)software configured by Varian linear accelerator has comprehensive performance and short testing time,which can satisfied the clinical quality verification requirements of Linac.At present,it has been widely used in the morning check of Linac.In order to ensure the accuracy and stability of the MPC software,this paper introduces the mechanical performance and image quality calibration and maintenance of the image system,so that the operators can be familiar with the calibration and maintenance system,so as to create a good equipment environment for the smooth progress of clinical treatment.
