Description
Adjusts the scale factor of the Pulsed Repetition
Frequency (PRF).
Optimizes hemodynamic flow conditions.
Low – allows maximum sensitivity to low velocity
flows. The system achieves this by incorporating the
lowest possible filter settings and lower PRFs. You
may experience increased flash.
General – produces an optimal balance between
flash (motion artifacts) suppression and maximum
sensitivity by using an adaptive wall filter.
High – optimizes the system for the high arterial
flow common to pulsatile vessels and stenotic
conditions.
Switches the colors depicting forward and reverse flow
in the Color ROI and the color bar.
Adjusts the threshold for choosing to display Color or
2D-mode data for any pixel.
Changes the transmit frequency of an active
multi-frequency transducer during Color.
Activates and deactivates the adaptive wall filter.
Adjusts the balance between the image line density
(resolution) and the frame rate. Increasing the line
density increases resolution and decreases frame rate.
Adjusts the relative baseline position upward and
downward. A shift in the baseline adjusts the range of
displayed flow velocities without changing the
system PRF.
Determines how long the colors corresponding to blood
flow velocity remain in the Color ROI before decaying
or being replaced by another color.
Adjusts the level of spatial (both axial and lateral)
averaging used to smooth the flow pattern display.
Selects a processing curve that assigns the velocity
range to a range of colors.
Activates and deactivates the Color information in the
ROI. The default setting is to display Color.
