5-2-5 Description of Hardware Options
5-2-5-1 CW - Continuous Wave Doppler
CW Doppler mode provides real time spectral analysis of CW Doppler signals. This information
describes the Doppler shifted signal from the moving reflectors in the CW Doppler beam. CW Doppler
can be referenced through a small pencil probe or phased array scan head, but it can also be used in
conjunction with a 2D image which has an M-line superimposed on the 2D image indicating the position
of the Doppler sample volume. For through-the-beamformer CW, this beam is steerable by the operator,
and is done by adjusting the location of the M-line. The CW Doppler beam, or M-mode line, can be
steered allowing interrogation along an operator-selected line within the image.
This option can be upgraded by implementing the CW-Doppler board (RSW).
