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.
Activates a background enhancement of solid color. The
solid background color changes, depending on the
power map selected.
Adjusts the threshold for the amplitude of the Power
display.
Changes the transmit frequency of an active
multi-frequency transducer during Power mode.
Balances low flow sensitivity with flash suppression.
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 time over which power data are processed
in calculating the power amplitude display.
Adjusts the level of spatial (both axial and lateral)
averaging used to smooth the flow pattern display.
Selects a processing curve that assigns flow amplitudes
to color levels.
Activates and deactivates the Power information in the
ROI. The default setting is to display Power.
