While patient entrance surface dose rate is an important indicator of dose performance for fluoroscopic units, there has been no standardized approach to measuring this. Since results are strongly dependent on the type of phantom used and the relative positions of the X-ray tube, intensifier and phantom, comparisons of the performance for different units are difficult to make. This document sets out a protocol for making these measurements using a standard phantom and standard configurations for different types of X-ray unit Values of dose rates which might be expected are given.
虽然患者入口表面剂量率是荧光透视设备剂量性能的一个重要指标，但目前尚无测量该指标的标准化方法。由于测量结果在很大程度上取决于所使用的体模类型以及X射线管、影像增强器和体模的相对位置，因此很难对不同设备的性能进行比较。本文档规定了使用标准体模和不同类型X射线设备的标准配置进行这些测量的方案，并给出了预期的剂量率值。
