A gray map determines the displayed brightness of an echo in relationship to its amplitude.
A Chroma Map determines the displayed Color of an echo in relationship to its amplitude.
Depending on individual requirements a "harder" or "softer" image can be obtained with this function
and can be adjusted in Read- and in Write-Mode (post-processing). The displayed gray scale wedge
corresponds to the adjusted gray map curve.
Different gray map curves can be related to a 2D image, M image, D image and 3D Volume.
