标准范围

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。高达13线对的像质计可以有效地用于管电压高达600千伏的情况。超过13对线的像质计可以在低于225千伏的管电压下有效使用。当使用兆伏范围内的电源电压时，结果可能不完全令人满意。

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.
