5-114 Image Optimization
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]: select the next cycle.
[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.
Time Mark
According to the status of the current section, tap the corresponding key on the touch screen to check
the matching time.
[AVO]: displays aortic valve open time.
[AVC]: displays aortic valve closure time.
[MVO]: displays mitral valve open time.
[MVC]: displays mitral valve closure time.
Curve Display
Select [Parameter] on the soft menu, the system provides different curves of different segments for
observation.
