6.3.3 TDI Mode
NOTE:
TDI imaging is only applied to cardiac applications by using the phased array probes.
TDI (Tissue Doppler Imaging) is a color ow imaging technique which detects the low frequency signal reected
from the cardiac muscle. TDI provides the ow 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.
