6. Press freeze and scroll with the trackball to End Systole where the cardiac chamber is
the smallest
7. Select Trace method 3 point or manual via OLED
a. Press the Pointer and place 3 points (or at least 6 points for manual) on the B Mode
image endocardial surface
8. Double press a Set key to complete the placement. System generates a 3 layered
trace
9. Adjust the trace by pointing to any dot along the trace and pressing set to move the dot
to desired location and then press Set to release the dot in the new location.
10. Adjust the Trace points and thickness if necessary.
11. When satisfied with the trace, press the Start Tracking OLED
12. System plays the BMode/Trace
13. If acceptable tracking results, press the OLED Accept and Compute
14. System generates curves from the trace and automatically plays back the B
Mode/Strain strip in unison.
15. Select the Bull’s Eye OLED for numerical Bull’s Eye data representation
16. Change the Parameter displayed using the OLED.
17. Store or Export data as desired.

Tracking Cycles
1 or 3
Number of heartbeats to evaluate
Cycle
• If Tracking Cycle is set to 1, this OLED will reflect 1 number corresponding to the
heartbeat in that clip that is to be evaluated (for example, if the clip has 6 heartbeats
in it and Cycle reflects 4, the system will evaluate the 4
th
heartbeat in the clip.)
•
If Tracking Cycle is set to 3, this OLED will reflect a range (1-3, 2-4, 3-5, 4-6)
corresponding to the three consecutive heartbeats that will be evaluated.
Trace
3Point or Manual
Manual: place at least 6 points in a clockwise or counterclockwise pattern along the
endocardium
• A4C, A2C, ALAX, PSAX B, PSAX M, PSAX AP
3 Point: 1 point on each annulus and 1 point at the apex (on the endocardial surface)
• A4C, A2C and ALAX
Tracking Points
Adjusts the number of points placed within each segment.
Thickness Adjusts the trace thickness (the distance between the endocardium and epicardium)
Start Tracking
After a trace has been drawn, press this OLED and system will generate a three layered
myocardial trace which moves with the underlying BMode image.
Display Effects Turns the arrow vector graphical display of the myocardial movement.
Play/Pause
Adjust to play/change playback speed or pause/move frame by frame
Accept and Compute Press to Accept the trace; start the calculation, and display the curves.
