摘要
本文主要介绍采用10cm的长杆电离室分组测量后求和的方式,检测标称射线宽度160mm的CT设备剂量指数的操作方法,阐述了传统标准器解决新发展仪器的检测问题,保证量值的准确传递。
This article mainly introduces the method of detecting the dose index of a CT device with a nominal ray width of 160mm by using a 10cm long rod ionization chamber and adopting the method of grouping measurement and final summation.The solution to the detection of the newly developed instruments byusing the traditional stand-ard instruments is explained,ensuring the accurate transmission of measured values.
