Operation Manual
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.
