Color display in ultrasonography.

Color display is useful in medical ultrasonography to increase sensitivity to contrast, to improve quantitative comparability between image regions, and to allow multiparameter display. In its first section this paper expands upon these objectives, sets forth the concepts of color definition, and discusses the criteria that should be used to select a pseudocolor display scale. The second section surveys the published work applying color display in ultrasonography, and the final section presents some of our recent results on (1) producing continuous pseudocolor scales with a natural order and with the property that equal changes in driving signal produce equally perceptible changes along the pseudocolor scale; and (2) applying these scales to ultrasound images.
