标准摘要
[中文适用范围]： 本文件规定了确定射线照片和射线透视图像的总图像不清晰度和基本空间分辨率的方法。 具有多达 13 个线对的 IQI 可以有效地使用高达 600 kV 的管电压。 超过13对线对的IQI可以在低于225 kV的管电压下有效使用。 当使用兆伏范围内的源电压时，结果可能不完全令人满意。 [外文原描述]： This document specifies a method of determining the total image unsharpness and basic spatial resolution of radiographs and radioscopic images. The IQI with up to 13 wire pairs can be used effectively with tube voltages up to 600 kV. The IQI with more than 13 wire pairs can be used effectively at tube voltages lower than 225 kV. When using source voltages in the megavolt range, it is possible that the results are not be completely satisfactory.
