In fact, this definition is adapted directly from the physical definition of electrical power. The ideal observer signal to noise ratio (snr) has been derived from statistical decision theory for all of the major medical imaging modalities.This snr provides an absolute scale for image system performance assessment and leads to instrumentation design goals and constraints for imaging system optimisation since no observer can surpass the performance of the ideal observer. The tables … Significantly higher levels (e.g., SNR=100) or extremely high levels (e.g., SNR=1000) do not provide appreciably better results. Industry standards define sensitivity in terms of the ISO film speed equivalent, using SNR thresholds (at average scene luminance) of 40:1 for "excellent" image quality and 10:1 for "acceptable" image quality.[1].
