本欧洲标准规定了放射摄影胶片数字化处理的基本性能参数的评估程序，如空间分辨率和空间线性，密度范围，密度对比敏感度和特征传递曲线。它们可以集成到系统软件中，并与用于数字化过程的质量控制的标准参考电影（如第5节所述）一起。该参考电影提供了一系列性能评估测试目标。测试目标适用于评估空间分辨率低至25微米的数字化系统，密度对比灵敏度低至0.02光密度，密度范围为0.5至4.5，胶片尺寸容量为（350 x 430）mm²。本标准不涉及数字化数据的信号处理和显示

This European Standard specifies procedures for the evaluation of basic performance parameters of the radiographic film digitisation process such as spatial resolution and spatial linearity, density range, density contrast sensitivity and characteristic transfer curve. They can be integrated into the system software and together with a standard reference film (as described in clause 5) used for quality control of the digitisation process. This reference film provides a series of test targets for performance evaluation. The test targets are suitable for evaluating a digitisation system with a spatial resolution down to 25 µm, a density contrast sensitivity down to 0,02 optical density, a density range of 0,5 to 4,5 and a film size capacity of (350 x 430) mm². This standard does not address signal processing and display of the digitised data.
