Color Flow Mode and Color M-Mode are Doppler Modes
intended to add color-coded qualitative information concerning
the relative velocity and direction of fluid motion within the
B-Mode or M-Mode image.

No In certain applications, you can quickly select the flow state via a
shortcut on the Color Flow Mode Touch Panel menu.
No Gain amplifies the overall strength of echoes processed in the Color
Flow window or spectral Doppler timeline.
Yes Increases/decreases the Scale on the color bar.
No Filters out low flow velocity signals. It helps get rid of motion artifacts
caused from breathing and other patient motion.
Yes Color Width sizes and positions the color window.
No Lets you view blood flow from a different perspective, e.g., red away
(negative velocities) and blue toward (positive velocities). You can
invert a real-time or frozen image.
NOTE: Invert reverses the color map, NOT the color Scale.
No Changes the Color Flow or Doppler spectrum baseline to
accommodate higher velocity blood flow. Minimizes aliasing by
displaying a greater range of forward flow with respect to reverse
flow, or vice versa.
Baseline adjusts the alias point. The default baseline is at the
midpoint of the color display and at the midpoint of the color bar
reference display.
Yes You can slant the ROI of the Color Flow linear image left or right to
get more information without moving the probe. The Angle Steer
function only applies to linear probes.
No Accumulation enhances the flow in an image.
Available in Contrast, Color Flow, and PDI.
Yes Optimizes the Color Flow frame rate or spatial resolution for the best
possible color image.
No Allows you to select a specific color map. After you have made your
selection, the color bar displays the resultant map.
No Threshold assigns the gray scale level at which color information
stops.
No Averages color frames.
No Brings out the tissue behind the color map.
