Today the range of image-recording systems in film mammography is so wide that an evaluation is only possible taking each and every technical parameter into account. The signal-to-noise ratio as defined in our earlier publications (10, 11) comprises all of these parameters. Trying to define the signal-to-noise ratio, especially the calculation of noise energy remains controversial and problematic. As its equivalent, the so-called noise-equivalent pass band of the human visual system for the different detail sizes is used. The signal-to-noise ratio is depicted as a matrix in an isometric plot. It demonstrates all of the imaging qualities of the recording system within the range covered by the experimental measurements. Different quality definitions of information theory, such as information quality and information capacity, can be deduced from the signal-to-noise matrices, enabling a comparison with digital storage media.
