4—Display curve: Velocity/Displacement/Strain/Strain Rate.
Each curve on the image is matched with a certain segment in the cardiac segmentation model (6),
identified by different colors.
Velocity curve
X-axis represents time (s);
Y-axis represents velocity (cm/s).
Displacement curve X-axis represents time (s);
Y-axis represents displacement (mm).
Strain curve X-axis represents time (s);
Y-axis represents deformation of the tissue (%).
Strain-rate curve X-axis represents time (s);
Y-axis represents strain by time (s
-1
).
5—Displays corresponding time of AVO (aortic valve open)/AVC (aortic valve close)/MVO (mitral valve
open)/MVC (mitral valve close).
6- Displays cardiac segmentation model, and each segment name is illustrated beneath the model.
In the figure, marks the peak position of the curve.
Under tracking status, click on a segment in the cardiac segmentation model. The segment has “X”
mark and its corresponding calculating is eliminated.
 Tap certain segment in the cardiac segmentation model, the segment will turns grey and its
corresponding curve no longer displays.
 You can get the current X/Y axis value by moving the cursor onto one point on the curve; and if you
press <Set> at this time, the frame marker will move to the spot.
 The segment boundary color indicates the tracking quality.
5.16.3 Select Image and Cardiac Cycle
You can select images with a better image quality so as to guarantee the analysis result.
 Switch the cine file
1. Tap [Review] to enter the review state on touch screen.
2. Double-click the target file;
3. The system closes current displayed file and switch to the newly selected file;
 Switch cardiac cycle within the cine file
Tap [Circle] to select when opening a cine which includes multiple cardiac cycles.
5.16.4 Myocardial Boundary Tracing
 The system provides 2 kinds of tracing method for 2 kind of sections:
 Long axis section (A4C, A2C, ALAX): 3-point method and manual tracing method are both
available.
 3-point method
