Chapter 7 Diagnosis Modes
TDW Mode
TDW stands for Tissue Doppler Wave. It visualizes the movement of rapidly moving tissues such as the
heart. TDW Mode is available in the PW Spectral Doppler Mode. If it is used in Spectral Doppler Mode
along with Color Doppler mode, changes in cardiac tissues over time can be observed.
NOTE: This can only be used when the cardiac application is selected in Phased Array Probe.
Starting and Ending TDW Mode
Tap TDW on the touch screen in PW Spectral Doppler Mode to run it. Pressing the button once
more switches the mode from TDW to PW Spectral Doppler.
NOTE: For information about the touch screen menu, refer to the ‘PW Spectral Mode’ section.
