标准摘要
[中文适用范围]： 本文件规定了使用IQI（像质计）确保射线照相图像质量统一的最小像质值。本文件适用于ISO 5579中规定的射线照相技术的A类和B类两种检测类别，并规定了这两种检测类别对应的最小IQI值。本文件适用于ISO 19232-1中规定的线型IQI和ISO 19232-2中规定的阶梯/孔型IQI这两种类型的像质指示器，以及ISO 5579中规定的A类和B类两种检测类别。 [外文原描述]： This document specifies the minimum image quality values (using IQIs) to ensure a uniform radiographic image quality. This document specifies the minimum IQI values for the two testing classes, A and B, of radiographic techniques as specified in ISO 5579. This document is applicable to the two types of image quality indicators as detailed in ISO 19232-1 for wire-type IQIs and ISO 19232-2 for step/hole-type IQIs, and for the two testing, classes A and B, as specified in ISO 5579.
