High Resoltn (Resolution) Color Flow Display Threshold
Description
Provides a quick way to maximize
resolution for the CFM display. Color flow display threshold is the gray
scale level at which the overlay of color
information stops.
If the display threshold is set at a gray
shade percentage of 34, any color
information available will be overlaid below
34% of the gray scale map. Color
information will not be placed on top of any
part of the gray scale greater than 34% of
maximum (white).
Benefits Optimizes CFM color display by changing
system parameters to maximize color line
density. Can limit color flow overlay to low level
echoes inside vessel walls. Helps
minimize color “bleeding” outside vessel
walls.
Values When High Resoltn is highlighted in the
sub-menu display, the function is on.
When it is not highlighted, it is off.
Pre-processing function.
Post processing function. The color
threshold can be set on real-time or frozen
images.
The settings cycle through the following
values:
0% to 100% of the gray scale in 3%
increments.
Affects on
Other Controls High Resolution will cause the scan frame
rate to decrease.
Color Capture (option)
Description Displays the highest mean velocity
(average velocity) detected over a specific
time interval.
NOTE: If a velocity map is selected, the
image displays accumulated peak mean
velocities. If a variance map is selected,
the image displays variance for the
accumulated peak mean velocities.
Benefits Useful in making slide presentations. Also
refer to the
6–14 for post processing Cine
Capture and Capture Frame functions.
Values Off, 0.5 seconds, 1 second, 2 seconds
and ECG.
