5.14.7 Exiting the Stress Echo Feature
To exit the Stress Echo feature:
Press the <End Exam> key on the control panel or click [End SE exam] on the screen.
5.14.8 Measurement and Report
Suspend the stress echo exam by selecting [Suspend Exam] on the soft menu. Press the measurement
related keys or buttons to enter cardiology measurement. For details, see the [Advanced Volume].
Reports contain the entered indication, if any, and also any entered comments that are specific to the
report. You can include or exclude data from specific phase(s). You can preview and print the report for
the currently selected mode. You can also enable colored report printing in Maintenance.

Entering Indications or Comments for the Reports
You can enter an indication for display in Stress Echo reports.
To enter an indication:
1. Press <Report> on the control panel to open the report.
2. Use the keyboard to enter text in the Indication dialog box and then click [OK].
5.15 Tissue Tracking Quantitative Analysis (QA)
Apart from the TDI imaging function, the system also provides a tissue tracking QA function for
myocardial movement evaluation.
Using the tissue tracking QA function, the ultrasound system will scan each pixel position by frame
within the cardiac cycle, then use the region matching method and auto-correlation searching method to
trace each spot and calculate the movement, so as to determine myocardial motion in a more
quantitative way.
CAUTION:
Tissue Tracking Quantitative Analysis images are provided for reference
only, not for confirming diagnoses.
Tissue tracking feature is an option.
The phased probes in cardiac exam modes support the tissue tracking QA function.
5.15.1 Basic Procedures for Tissue Tracking QA
1. Select a saved B mode cardiac cine file (a cin. format file which contains more than 1 cardiac cycle
(with 2 R waves) and ECG signal).
2. Touch [TT QA] on the touch screen to activate the function:
a) You can determine the image of interest by previewing the image
b) To find the image of interest, roll the trackball or rotate the knob under [Cycle] on the touch
screen to select.
Select the corresponding section name on the touch screen and press <Cursor> to show the cursor.
Use the cursor to set the reference point (for details, see chapter “5.15.4 Myocardial Boundary
Tracing”):

Long axis section: use the “3-point” method or “Manual” method to set

Short axis section: enter multiple points (at least 6 points) using the cursor manually to set.
3. After reference points are set, the system will display the boundary of the endocardium and
epicardium. Adjust the thickness if necessary.
If the traced result is poor, touch [Reload] on the touch screen to re-trace the reference points, or
make fine adjustments to the points using the cursor.
If the cycles are not adequate to provide the information, switch to another cycle to trace.
