Delete the Sample Line
Click the sample line to select it, and click [Delete] to delete the selected line and you can
re-depict a new sample line.
Tips:
Parameters of Free Xros M mode and Free Xros CM mode are dependent from each
other, but their functions are the same, parameters of Free Xros CM are not to be
introduced, please refer to relevant sections of the M mode and Free Xros M mode.
5.9 TDI
TDI mode is intended to provide information of low-velocity tissue motion, specifically for
cardiac movement.
There are 4 types of TDI mode:
z
Tissue Velocity Imaging (TVI): This imaging mode is used to detect tissue
movement with direction and speed information.
z
Tissue Energy Imaging (TEI): This imaging mode reflects the status of cardiac
movement by displaying the intensity of tissue, the brighter the color the less the
intensity.
z Tissue Velocity Doppler Imaging (TVD): This imaging mode provides direction
and speed information of the tissue quantificationally with doppler spectrum.
z
Tissue Velocity M Imaging (TVM): This function assists to observe the cardiac
motion through a direct angle. TVM mode is also called Color Tissue M mode,
refer to "5.10 Color M Mode" for details.
„ Only phased probe is valid for TDI function.
5.9.1 TDI Exam Protocol
„ Enter TDI
