Description
Scale
Scale adjusts the range of velocities that are displayed. Upward
presses increase scale and downward presses decrease it.
Baseline
The Baseline control adjusts the Doppler baseline. Upward
presses move the baseline up on the screen and downward
presses move the baseline down.
Image Type
Strip Doppler supports image presets for Low Flow, Medium
Flow, and High Flow.
Invert
Normally signals above the baseline are positive velocities
(moving toward the transducers). However, when Invert is
pressed then negative velocities are above the baseline. Invert
does not affect the baseline position.
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.
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
presents a flat spectrum, while a low dynamic range presents a
large range of spectrum brightness.
