Tissue Tracking
Tissue Tracking calculates and color-codes the displacement in
tissue over a given time interval. The displacement is found as
the time integral (sum) of the tissue velocities during the given
time interval. The color-coded displacements calculated in the
myocardium are displayed as color overlay in the respective
acquisition window.
By studying the color patterns generated in the different
segments, the user can confirm the standard segmental wall
motion scoring at peak levels.
To display Tissue Tracking
1. Press T in one of the Wall segment diagram field (usually an
apical view at peak level).
The Tissue Tracking color overlay is displayed in the
Acquisition window.
Quantitative analysis
Quantitative analysis enables further analysis based on multiple
tissue velocity traces. Quantitative analysis is performed using
the Quantitative analysis package described in Chapter
‘Quantitative Analysis’ on page 9-1.
To start quantitative analysis
1. Press Q in one of the Wall segment diagram field (usually
an apical view at peak level) to launch the Quantitative
analysis package (page 9-1).
