摘要
尽管现代放射诊断设备非常先进 ,但在经历了一段时间运行后 ,它的实际输出有可能发生改变 ,并由此影响诊断质量或者增加病人及医务人员照射剂量。为了时刻保证仪器设备的正确输出 ,完善的质量保证计划为此提供了可能。本文列举出了普通的 X射线诊断设备常用的质量控制实验实施目的、方法、允许误差等 。
Although the radiodiagnosis equipment is advanced, the actual output magbe changed when it has worked for some time. This may affect the quality of x ray or lead to cases of unnecessary radiation exposure to workers and patients. In order to ensure the proper output, the quality assurance program should be organized. In this paper, the purpose, procedures, acceptable variations of the quality control for general X ray equipment are listed and they will be useful to clinic practice.
