Selection Tool Tip Description Settings
PRF PRF Adjusts the scale factor of the Pulsed Repetition
Frequency (PRF). Transducer-
dependent
Flow Flow State 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.

Backgrd Background Activates a background enhancement of solid color. The
solid background color changes, depending on the
power map selected.
On, Off
Priority Tissue Reject
(Priority) Adjusts the threshold for the amplitude of the Power
display. 0 to 4
(current
setting) Transmit
Frequency Changes the transmit frequency of an active
multi-frequency transducer during Power mode. Transducer-
dependent
Filter Wall Filter Balances low flow sensitivity with flash suppression. 0 to 3
R/S Res/Speed Adjusts the balance between the image line density
(resolution) and the frame rate. Increasing the line
density increases resolution and decreases frame rate.
0 to 5
Persist Persistence Adjusts the time over which power data are processed
in calculating the power amplitude display. 0 to 4
Smooth Spatial Averaging
(Smoothing) Adjusts the level of spatial (both axial and lateral)
averaging used to smooth the flow pattern display. 0 to 3
Maps Maps Selects a processing curve that assigns flow amplitudes
to color levels. A, B, C, D, E,
F, G, H
Display Display Color Activates and deactivates the Power information in the
ROI. The default setting is to display Power.
