PW Spectral Doppler Mode
PW stands for Pulse Wave. PW Spectral Doppler Mode gives information on the speed of blood flow at
a specific 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 flow 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.
