Where the balance orientation line is on a gray step, the gray value will be displayed (only if a
color value is present.
For example: If the gray value is higher than 96 while a color value is present, the gray value
will be displayed.

The baseline shift can be used to prevent aliasing in one flow direction similar to the PW
Doppler baseline shift. Shifting the baseline enlarges the velocity range in one direction. The
zero line of the color bar is also shifted.
Adjust the zero line with +/-
There are 8 steps in each direction. By step 8 you see only the color wedge in one
direction (maximum velocity). The other direction is (kHz, cm/s, m/s).
The maximum value and minimum value of the flow velocities are displayed at the upper
and lower edge of the color wedge.

Dynamic refers to the compression of grayscale information into a suitable range for the
display. Dynamic allows enhancement of a certain grayscale range which makes it easier to
display pathology. It adjusts the displayed cutoff of the Doppler analysis waveform. + to
decrease brightness (more gray shades/less contrast) - to increase brightness (fewer gray
shades/ more contrast)

This function controls the number of pulses for one displayed line. Since several pulses are to
be evaluated for displaying a result, the color display quality increases with the number of
evaluated pulses. With increasing Ensemble the frame rate decreases.
Select +/- on the [Ensemble] key and select the number of pulses per color line.
