TDI Mode (Tissue Doppler
Imaging)
Tissue Doppler Imaging (TDI) captures the wall motion of vessels and creates a
color image displaying the tissue motion. TDI is a cardiography technique, so it
can only be used in cardiology application modes.
Like conventional Doppler mode, TDI also uses Doppler principle. However, in TDI
mode high amplitude (high intensity), low frequency tissue motion is quantified.
In contrast, in the conventional Doppler mode low amplitude (low intensity), high
frequency blood motion is quantified.
Attention!
Only phased array probes (2P1) are TDI capable.
