工频牙科X射线机测量加载时间（辐照时间）的注意事项

摘要

加载时间是医用诊断X射线机非常重要的安全性能指标，但是加载时间和辐照时间二者的定义并不明确，给测量带来了困难。本文论述了加载时间和辐照时间的关系和区别，以及测量工频牙科X射线机的加载时间中容易出现的问题和解决方法。%Loading time is a very important essential performance indicators of medical X-ray Equipment, but both the loading time and the irradiation time is not clearly deifned, that makes them dififcult to understand and measure in the inspect. This article discusses the relationship and distinction of loading time and irradiation time, and the problems and the solutions when measuring loading time of normal frequency of dental X-ray machine.
