Mindray Consona N9 - Screen Display of Tissue Tracking QA

6 Image Acquisition
Operator’s Manual 6 - 33
6.14.2 Screen Display of Tissue Tracking QA
1 Displays image used to generate
trace curve
/
2 Displays corresponding time of
AVO (aortic valve open)/AVC
(aortic valve close)/MVO
(mitral valve open)/MVC (mitral
valve close).
/
3 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
).
4 Displays ECG trace /
5 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.
