1
Threshold
Threshold assigns the gray scale level at
which color information stops.
2
Packet Size
Controls the number of samples gathered for
a single color flow vector.
3
Select Color maps
Allows a specific color map to be selected.
After a selection has been made, the color
bar displays the resultant map.
4
Adjust Frequency
Enables the adjustment of the probe’s
operating frequency. Press Frequency and
select desired value. The selected frequency
is displayed in the status window.
5
Set Frame Average
Averages color frames. Press Frame
Average up/down to smooth temporal
averaging.
6
Color Invert
Views blood flow from a different perspective.
Press Invert to reverse the color map.
7
Adjust LIne Density
Trades frame rate for sensitivity and spatial
resolution. If the frame rate is too slow,
reduce the size of the region of interest,
select a different line density setting, or
reduce the packet size.
For LOGIQ e, LOGIQ
e Vet and LOGIQ i
Adjust Frame Rate
Trades frame rate for sensitivity and spatial
resolution. If the frame rate is too slow,
reduce the size of the region of interest,
select a different line density setting, or
reduce the packet size.
For Vivid e
8
Activate Spatial Filter
Adjust Spatial Filter to smooth out the color,
makes it look less pixely.
9
Adjust Dynamic Range
Dynamic Range controls how echo
intensities are converted to shades of gray,
thereby increasing the adjustable range of
contrast.
10
Activate ACE
Eliminates the motion artifacts. Press Ace to
activate.
11
Adjust Angle Steer
Slants the Color Flow region of interest or the
Doppler line to obtain a better Doppler angle.
12
Move Baseline
Adjusts the baseline to accommodate faster
or slower blood flows to eliminate aliasing.
