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
).
