TDW Mode
TDW stands for Tissue Doppler Wave. TDW mode represents the movements of 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 be used only when the cardiac application is selected in Phased Array Probe.

Starting and Ending TDW Mode
TDW Mode can be activated while in PW Spectral Doppler mode by pressing the soft menu’s dial-
button [6]. Pressing the button once more switches the mode from TDW to PW Spectral Doppler.
