Image Optimization 5-29
6. Define the next point using the trackball and <Set> key (touch [Undo] to cancel the current point
and activate the preview point). The system updates the time-motion curve in real time. The sample
line is displayed in green, and each point is marked with a number in sequence.
7. Repeat Step 6 to finish the sample line.
8. Double-click the <Set> key to end editing. The sample line is displayed in white.
9. Adjust the image parameters to optimize the image, obtain the relevant tissue image for data
analysis, then save the image if necessary.
10. Press the user-defined key again or <B > to exit Free Xros CM mode.
Sample Line Modification
1. To enter curve (sample line) modification status:
For a completed sample line, set [Edit] to “On” and the sample line is editable.
2. Anchor the cursor to a certain point, press the <Set> key to activate the point, then roll the trackball
to drag the point for a desired sample line.
3. Double-click the <Set> key to end editing. The sample line is displayed in white.
Delete a Sample Line
Touch [Delete] to delete the selected line. You can re-create a new sample line.
Tip:
The free Xros M mode and Free Xros CM mode parameters are independent of each other, but their
functions are the same. Free Xros CM parameters are not to be introduced. See the relevant M mode
and Free Xros M mode sections.
5.9 TDI
TDI mode is intended to provide information about low-velocity and high-amplitude tissue motion,
specifically for cardiac movement.
4 types of TDI mode are available:

Tissue Velocity Imaging (TVI): this imaging mode is used to detect tissue movement with
direction and speed information. In general, the warm color indicates movement toward the
probe, while the cool color indicates movement away from the probe.

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.

Tissue Velocity Doppler Imaging (TVD): this imaging mode provides quantifiable direction and
velocity information about the tissue.

Tissue Velocity M Imaging (TVM): this function assists in observing the cardiac motion through
a direct angle. TVM mode is also called Color Tissue M mode which has been introduced in the
Color M mode chapter. See “5.7 Color M Mode” for details.
TDI imaging and TDI QA are options. Cardiology Package should be configured first.
Only the phased probe in cardiac exam mode supports the TDI function.
5.9.1 Basic Procedures for TDI Imaging

Press user-defined key for TDI on the control panel in real-time scanning to enter the modes
(Assign a key as user-defined TDI: the setting path is "[Setup
]→ [System] →[Key Config]", see
“12.1.6 Key Configuration” chapter for details), or touch [TDI] on the touch screen directly:

In B or B+Color mode: to enter TVI Mode, TVI mode parameters will be displayed on the
touch screen.

In Power mode: to enter TEI Mode, TEI mode parameters will be displayed on the touch
screen.
