Chapter 7 Diagnosis Modes
PW Spectral Doppler Mode
PW stands for Pulse Wave. This mode displays the blood flow speed at a specific blood vessel location
within a specific 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 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.
[Figure 7.10 PW Spectral Doppler Mode]
Entering & Exiting PW Spectral Doppler Mode

Press the Set button on the control panel to obtain a spectral doppler image.
NOTE: The doppler image can only be obtained in the D Only or Simultaneous states.
PW Spectral Doppler Mode Screen
The doppler spectrum is displayed when the Sample Volume is located above the blood flow on the
2D image . The size of the Sample Volume is displayed in mm units. Use the trackball to adjust the
position of the Sample Volume.
