Doppler Controls
There are three Soft-Menu pages for Pulsed Wave Doppler (PWD) imaging adjustments.
Dynamic Range—Controls how echo intensities are converted to
shades of gray, thereby creating a range of gray scale that can be
adjusted.
Slant Scan—Controls the position of the Doppler cursor for linear
probes only.
Wall Filter—Removes the low level, low frequency Doppler signal
caused by movement of the vessel walls.
S. V. Length—Changes the size of the sample volume gate length.
Sweep Speed—Changes the speed at which the timeline updates
across the display.
Penet—Penetration can be increased by lowering the operating
frequency of the active probe.
Color—Allows for enabling PWD or CWD Mode image colorization.
Color Tag—Enables the colorization of a specific gray scale level
range.
Tag Positn—Allows for the movement of the specified color tag
range throughout the gray scale displayed.
