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.
Image Type
Strip Doppler supports image presets for Low Flow, Medium
Flow, and High Flow.
Angle Correct
Adjust the Doppler scale to account for the angle between the
Doppler cursor and the blood flow. Upward presses increment
the angle. Downward presses decrement the angle. Angles
above 80 are not allowed.
Quick-Angle
Adjusts the angle correct quickly to one of 60°/0°/-60°.
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.
Colorize
Switches between grayscale and tinted (pseudo-color)
postprocessing maps.
Gray Map
Tint
Adjusts the current postprocessing, either grayscale or tinted.
Dynamic
Range
The Dynamic Range, or log compression, adjusts how signal
intensities are converted to brightness. A high dynamic range
will display more shades of gray, while a low dynamic range will
display fewer shades of gray and a more contrasty Doppler
display.
