Color
Persistence
4-level, 0
～
3
Afterglow increases, low-velocity and
low-flow blood flow is easily displayed.
Color
Threshold
6-level, 0
～
5
Limits the display of color scale, eliminates
a lot of unnecessary noise.
Color Balance 16-level, 0
～
15 Adjust color brightness.
Color Smooth
High/Middle
/Low
Higher state, smoother blood flow, more
continuity, easy display.

Range
8-level, 30
～
100
Selecting different dynamic range can
significantly change the display of image.
Edge
enhancement
4-level, 0
～
3
Edge enhancement is to enhance the image
outline, so to strengthen the image edge
display, the value is greater, and the
enhancement is more obvious.
Compression
curve
8-level, 0
～
7
System built-in some gray-scale curves, to
adapt to the needs of different checking parts
and application range.
Select the different gray-scale curve; it will
significantly change the display of image.
Recommend 3.5MHz probe to choose 5;
6.5MHz probe to choose 2; 7.5MHz probe
to choose 1.
Image
post-process
8-level, 0
～
7
Level-adjustable, default is 2.
Frame
Average
4-level, 0
～
3
Frame average is weighted-mean for
adjacent B images to remove image noise,
remain more tissue information, and to make
images show clearer and softer.
The value is greater, the average effect is
more obvious; and the value is smaller, the
image’s original untreated information
remains more.
