An option is available to enhance CFM/PDI signal processing.
It requires the necessary hardware (Color Processing Board)
and software (CFM/PDI Enhancement). The following choices
are added to the CFM Mode Soft-Menu:

Noise Blanker
Description
Designed to reduce “color artifact noise”.
This noise can appear as a flash of color
synchronized with the heart beat while
scanning the abdomen. The noise may
also appear to fill the color window when
changing window size/position or when
moving the probe. Noise due to value
motion in cardiac studies may be
considered clutter noise.
Noise Blanker is intended to reduce the
random noise generated due to the
increase in Color Gain.
Benefits
Reduces the “color artifact noise” as
described in the description section.
Noise Rejection increases color sensitivity
with the ability to use higher color gains.
Very effective when observing low velocity
blood flow.

Other Controls
May have a tendency to reduce frame rate
due to increased CFM processor
functions.
Allows use of increased Color Gain or
equivalent results with less gain.
