PW Spectral Doppler Mode
PW stands for Pulse Wave. PW Spectral Doppler Mode gives information on the speed of blood ow at
a specic site in the form of a spectral trace and audio signal. Distance (depth) information can also be
obtained by transmitting pulses over time frames.
This mode is useful for measuring low-speed blood ow such as in the abdomen and peripheral vessels.
The 2D Mode image is also shown, allowing the marking and adjustment of an observation area within
the entire image.
