Gain
CFM: Increase the overall strength
of color flow echoes, but the color
map will not be affected.
PDI: Power Doppler Imaging. The
larger the gain the more number of
reflectors and the brighter of the PDI
map.

Flow Type
This function is used to optimize
flow images quickly according to
current flow state. And values of
associated parameters will be
changed together with it.

Dual Live
On: the window will be automatically
switched to the dual real-time status
(the left one is B image, and the
right one is B+Color/PDI image).
Off: non-dual-live status.
On/Off
Persist
The bigger the value, the more
persistence among frames, and the
more continuity of color maps.
0-7
Smooth filter
Adjust to smooth out the color
image. Similar to spatial smooth.
The bigger the value, the stronger
the effect.
0-7
WallFilter
Filter out low velocity flow signals in
order to hide unusable motion. It
helps to get rid of motion artifacts
caused from breathing and other
patient motion. The bigger the
value, the more signals of low
velocity will be filtered out.
0-7
PRF
Adjust to raise or lower the flow
velocity range. The bigger the
value, the higher the maximum
velocity will be detected. Frame rate
will be affected by excessive lower
PRF. Aliasing may occur if low
velocity range is set for high velocity
flow.
