Baseline
: adjust the baseline to accommodate faster or slower blood flows to eliminate aliasing.
Angle
: optimize the accuracy of the flow velocity. It estimates the flow velocity in a direction at an angle to
the Doppler vector by computing the angle between the Doppler vector and the flow to be measured. This is
special useful in vascular applications where you need to measure velocity.
Doppler Gain
: allow you to control the background information of spectral.
Sweep Speed
: control speed of spectral update.
Doppler Sample Volume Gate Position and Size (Trackball and ENTER)
Move the sample volume on the B mode’s Doppler cursor. The gate is positioned over a specific position
within the vessel.
To move Doppler cursor position, turn the trackball left or right until positioned over the vessel.
To move sample volume gate position, move the trackball up or down until positioned inside the vessel.
To size sample volume gate, press
[ENTER]
key to toggle trackball function from sample volume gate
positioning to sizing, then move the trackball to change sample volume gate size.
