5.4.2. CW Image Optimization
The following touch controls can be used to optimize the CW image.
Scale adjusts the range of velocities that are displayed.
Upward presses increase scale and downward presses
decrease it.
The Baseline control adjusts the Doppler baseline. Upward
presses move the baseline up on the screen and
downward presses move the baseline down.
Strip Doppler supports image presets for Low Flow,
Medium Flow, and High Flow.
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.
Adjusts the angle correct quickly to one of 60/0/-60.
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.
Switches between grayscale and tinted (pseudo-color)
postprocessing maps.
