WebApr 2, 2024 · Signal-to-noise ratio (SNR) is a generic term which, in radiology, is a measure of true signal (i.e. reflecting actual anatomy) to noise (e.g. random quantum mottle).A lower signal-to-noise ratio generally results in a grainy appearance to images. In radiography, the signal-to-noise ratio, and thus the apparent noisiness of the image, is proportional to the … WebThe swell of a wave in the ocean, and the subsequent dip that follows, is simply a vibration or oscillation of the water at the ocean’s surface.
