标准摘要
[中文适用范围]: 本欧洲标准规定了射线照相胶片数字化过程的基本性能参数的评估程序,例如空间分辨率和空间线性、密度范围、密度对比灵敏度和特征传递曲线。 它们可以集成到系统软件中,并与标准参考胶片(如第 5 条所述)一起用于数字化过程的质量控制。 该参考片提供了一系列用于性能评估的测试目标。 测试目标适用于评估空间分辨率低至 25 μm、密度对比灵敏度低至 0.02 光密度、密度范围 0.5 至 4.5 以及胶片尺寸容量 (350 × 430) 毫米。 该标准不涉及数字化数据的信号处理和显示。 [外文原描述]: ISO 14096-1:2005 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 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 micrometres, 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) mm 2 . This standard does not address signal processing and display of the digitised data.
