ISO 14096-1:20 05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,如空间分辨率和空间线性度、密度范围、密度对比灵敏度和特征转移曲线。它们可以集成到系统软件中,并与标准参考胶片一起用于数字化过程的质量控制。该参考膜为性能评估提供了一系列测试目标。测试目标适用于评估数字化系统,其空间分辨率低至25微米,密度对比灵敏度低至0.02光密度,密度范围为0.5至4.5,薄膜尺寸容量为(350 x 430)mm2。该标准不涉及数字化数据的信号处理和显示。
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) mm2. This standard does not address signal processing and display of the digitised data.
