Baseline
The Baseline control adjusts the Color baseline. Upward
presses move the baseline up on the scale and downward
presses move the baseline down. Baseline is not available in
PDI mode.
Invert
Normally, signals above the baseline are positive velocities
(moving toward the transducer). However, when Invert is
pressed then negative velocities are above the baseline. Invert
does not affect the baseline position. Invert is not available in
PDI mode.
Wall Filter
The Filter control removes excessive noise from movement of
vessel walls. Options of Low, Med. and High are available.
Higher wall filter level will suppress more strong single of the
vessel walls, but low flow signal will be missing.
Map
Adjusts the current map for the active color variation.
Persist
Persistence determines the number of frames that are
averaged together for display. Levels of Off, Low, Med. and
High are available.
Smooth Filter
The smoothness filter determines the spatial filtering that is
applied to the Color image. Higher filter levels create a
smoother image. Upward presses increase the filter. Downward
presses decrease the filter.
Threshold
When the system receives both B-mode and color signals from
a region within the Color ROI box, the Threshold determines
whether to display overlapping signals as grayscale or color.
In Color mode, higher Threshold values display more color, and
lower Threshold values display more grayscale.
Upward presses increase threshold. Downward presses
decrease threshold.
