3. Adjust color flow ROI.
−
Move the trackball to position color flow ROI.
−
Press the confirm key on the control panel to adjust the size of color flow ROI.
−
Press the confirm key again to reposition color flow ROI.
4. Optimize the PDI-mode image. For details, refer to Section 6.3.4 Optimizing CFM/

3 TDI Mode
NOTE:
TDI imaging is only applied to cardiac applications by using the phased array probes.
TDI (Tissue Doppler Imaging) is a color flow imaging technique which detects the low
frequency signal reflected from the cardiac muscle. TDI provides the flow information of
velocity and direction for cardiac movement.
TDI uses the low velocity and the high amplitude adjusted from the wall filter to create a
color-coded tissue imaging.
Perform the following steps to acquire TDI-mode images.
1. Optimize a B-mode image.
2. Press the CFM key on the control panel, and then tap TDI on the touch screen to
enter the TDI mode.
