摘要
作者使用从美国进口的一套放射诊断质量保证（ＱＡ）检测仪器，参照美国医学物理学家协会（ＡＡＰＭ）推荐的方法和规程，对一批Ｘ线诊断设备进行了输出量与线性的检测。本文报告测量结果，分析受检设备的一些典型潜在故障，并就评价标准等作初步探讨。
The radiation output and linearity of several diagnostic X-ray units weremeasured by means of QA testing set from USA according to the procedures andprotocols recommended by American Association of Physicists in Medicine(AAPM).The measured results are reported and analysed,some typical exam-ples predicting the potential malfunctions of the X-ray units are given and thecriteria for evaluation are also discussed。
