PW and CW Doppler imaging

Pulsed wave (PW) Doppler and continuous wave (CW) Doppler imaging modes are optional features. The
default Doppler imaging mode is PW Doppler. In cardiac exams, you can select the CW Doppler on-screen
control.
PW Doppler is a Doppler recording of blood flow velocities in a range specific area along the length of the
beam. CW Doppler is a Doppler recording of blood flow velocities along the length of the beam.
You can use PW/CW Doppler and CPD/Color simultaneously. If CPD/Color imaging is on, the color ROI box
is tied to the D-line. The SELECT key cycles among color ROI box position; color ROI box size; the D-line
and gate location; and (in PW Doppler) angle correction. The active selection is highlighted. Also, the
indicator on the left-hand screen shows which touchpad function is active.
To display the D-line
