The screen contains the following result displays:
•
Tracked ROI
: A dynamic display of the tracked ROI to be
used for tracking validation. The tracked ROI has a texture
overlay indicating strain values according to the colormap.
The overlay may be turned off/on by clicking the
Color
button.
NOTE: Rejected segments will not have texture overlay.
•
Segmental result ROI
: A static display indicating the peak
strain value per segment. Rejected segments are displayed
with an
X
instead of a value. Clicking a segment changes its
rejection status (See ‘Tracking validation’ on
page 8-24 for
more information.
)
•
Strain traces
: A static display indicating the segmental and
global strain traces with time. The peak values are
indicated.
NOTE: The peak values can be adjusted by clicking and dragging
the peak markers with the mouse.
•
Curved anatomic M-mode
: A static display indicating a
curved anatomic M-mode along the center of the ROI. The
M-mode has a parametric overlay indicating peak strain
values.
NOTE: Rejected segments will not have texture overlay.
NOTE: The Segmental result ROI, Strain traces and Curved anatomic
M-mode are using color codes to link the different segments.
CAUTION
Segments and peak detection should be checked to make sure
that non-physiological traces are excluded in the calculation of
indices.
