Grayscale contrast enhancement based on greyscale-based contrast-to-noise ratio

Medical Imaging 2021: Image Perception, Observer Performance, and Technology Assessment, 2021
Subjective reading is still the majority way in current medical image diagnostics, and the visualization effect of images is one important factor which may affect the reading performance or diagnostic quality. In computed tomography (CT), CT numbers are converted into greyscale images by the display window settings.

A contrast ratio constraint on stereo matching

Proceedings of the Royal Society of London. Series B: Biological Sciences, 1995
Stereopsis employs differences in the location of features in the two eyes to reconstruct their relative depths. Computational models largely ignore the contrast of these features; they simply require them to be visible in each eye and to possess the same contrast polarity.

An analysis of elastographic contrast-to-noise ratio

Ultrasound in Medicine & Biology, 1998
We present a theoretical formalism and simulation results that allow the incorporation of the elastic contrast properties of tissues with simple geometries into the elastographic noise models developed previously. This analysis results in the computation of the elastographic contrast-to-noise ratio (CNRe).

The Generalized Contrast-to-Noise Ratio

2018 IEEE International Ultrasonics Symposium (IUS), 2018
Many adaptive algorithms claim to provide higher contrast than delay-and-sum (DAS). These claims are often backed by estimations of the contrast-to-noise ratio (CNR). Intuitively, we assume that higher CNR leads to higher probability of lesion detection, and this is indeed the case for DAS.
