Parameter Adjustment

[Thickness]: adjusts the tracing thickness, i.e., the distance between the endocardium wall and the
tracking points on the epicardium.

[Tracking Points]: adjusts the number of points within the segment.

[Cycle]: rotates clockwise to select the next cycle, and vice versa.

[Smooth]: adjusts the smooth effect of the curve.

[Display Effect]: turns on/off the arrow vector graphical display of the myocardial movement.

[Velocity Scale]: adjust the scale length of the velocity.

[Display Style]: display the endometrial, the epicardium, the myocardial or all.

[Tracking Cycles]: Select the cycles to be tracked.

[Average Cycles]: Obtain the average parameter curves of the tissue.

[Cycle Select]: Select among different cycles.
Image display
According to the status of the current section, touch the appropriate button on the touch screen to
check the corresponding time.

[AVO]: displays the aortic valve open time.

[AVC]: displays the aortic valve close time.

[MVO]: displays the mitral valve open time.

[MVC]: displays the mitral valve close time.
5.15.6 Bull’s Eye
After tracking, the system displays a Bull’s Eye graph for judging the reverse movement or scope of
myocardium.
1. Touch [Bull’s Eye] on the touch screen to turn the function on:
You can acquire:

Time to peak value and peak value of the 17 segments;

Display measurement result EDV/ESV/EF/TPSD.
2. Rotate the knob under [Parameter] on the touch screen to see a bull’s eye graph for different
parameters.
