Chapter 4 Diagnosis Modes
PW Spectral Doppler Mode
PW stands for Pulse Wave. This mode displays the blood ow speed at a specic blood vessel location
within a specic time frame. Distance (depth) information can also be obtained by transmitting pulses
over particular 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 the observation
area within the entire image.
