M Color Flow Mode
DescriptionM Color Flow is used for fetal cardiac applications. Color Flow 
overlays color on the M-Mode image using velocity and variance 
color maps. The Color Flow wedge overlays the B-Mode image 
and M-Mode timeline.
The Color Flow maps available in M-Mode are the same as in 
Color Flow Mode. The size and position of the Color Flow 
window in B-Mode determines the size and...

Intended Use
Color Flow Mode is a Doppler Mode intended to add color-
coded qualitative information concerning the relative velocity 
and direction of fluid motion within the B-Mode image.
Introduction
A typical examination using Color Flow Mode, 
1.  Follow the same procedure as described under B-Mode to 
locate the anatomical area of interest. 
2.  After optimizing the B-Mode image, add Color Flow....

Uses
Color Flow is useful to see flow in a broad area. Color Flow 
allows visualization of flow in the whole image, whereas Doppler 
Mode provides spectral information in a smaller area. 
Color Flow is also sometimes used as...
