PW/CW Doppler Mode Checks
Introduction
PW and CW Doppler modes are used to measure velocity (most
often in blood).
Doppler mode can be done with a special pencil probe or with
an ordinary probe. By using an ordinary probe, you can first
bring up a 2D picture for navigation purpose and then add PW/
CW Doppler.
