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