Image Optimization 5-37
The cursor displays as , and can be moved within the 2D image only.
5. Press <Set> to fix the start point, and
the digital number “1” is marked beside the point.
6. Define the next point using the trackball and <Set> (tap [Undo] on the touch screen to cancel the
current point and activate the preview point).The system updates the time-motion curve in real time.
The sampling line is displayed in green, and each point is marked with a number in sequence.
7. Repeat Step 6 to finish the sampling line.
8. Double click <Set> to finish the editing, and the sample line is displayed in white.
9. Adjust the parameters to obtain the desired tissue of Free Xros CM image. Then, save the image.
10. Press the user-defined key for Free Xros CM, or press <B> to exit.
Editing the curve
1. To enter:
After finishing the sampling line, tap [Edit] on the touch screen. The cursor becomes the icon .
2. Move the cursor over the curve. Press <Set> to activate the spot. Move the cursor to change the
shape of the curve.
3. Double click <Set> to finish the editing, and the sample line is displayed in white.
Removing the curve
Tap [Delete] on the touch screen to remove the curve.
NOTE: the way to adjusting the parameters is same with that in M mode in Free Xros CM.
5.10 TDI
TDI mode is intended to provide information of low-velocity and high-amplitude tissue motion,
specifically for cardiac movement.
There are 4 types of TDI mode available:

Tissue Velocity Imaging (TVI): This imaging mode is used to detect tissue movement with
direction and speed information. Generally the warm color indicates the movement towards the
transducer, while the cool color indicates the movement away from the transducer.

Tissue Energy Imaging (TEI): This imaging mode reflects the status of cardiac movement by
providing the energy information, the larger the energy is, the brighter the color becomes.

Tissue Velocity Doppler Mode (TVD): This imaging mode provides direction and speed
information of the tissue.

Tissue Velocity M Mode (TVM): This function assists to observe the cardiac motion through a
direct angle.
NOTE: TDI is optional.
The phase probes support the TDI mode under the cardiac exam.
The SC8-2U/D8-4U/SC5-1U/SC6-1U/D8-2U probes support the TDI mode.
