Invert
Reverse the color of blood flow.
Off: Red toward (positive velocities)
and Blue away（negative velocities）
On: opposite to the above.
On/Off
Menu controls
Base Line
Adjust the velocity range of forward
flow /reverse flow. Minimize aliasing
by displaying a greater range of
forward flow or reverse flow.
7 levels
Map
Each map displays velocity/power
according to colors.
In PDI mode, 7 kinds of maps are
provided: 0-3 belongs to Power
Doppler Imaging (PDI) Mode maps.
While, 4-7 belong to Directional
Power Doppler Imaging (DPDI)
Mode maps.
In Color mode:0-7
In PDI mode:
0-3 (PDI)
4-7 (DPDI)
Packet Size
The bigger the value, the stabler the
flow signals, but the frame rate will
be decreased. Adjust properly
according to practical applications.
4 levels: 8,10,12,14
Threshold
Set the gray scale level at which
strong echoes inside vessel walls
will be rejected. The smaller the
value, the lower the gray scale level,
and the more gray scales will be
recognized as echoes inside vessel
walls, and the information will be
rejected.
0-15
Freq
The lower the frequency, the better
the force of penetration; the higher
the frequency, the better spatial
resolution.
2 levels
Steer
Adjust the ROI steering angle of the
Color Flow linear image to get more
information without moving the
probe. The Angle steer function only
applies to linear probes.
