derived from endocardial deformation are suffixed Endo,
such as for instance GPeakSysSL(Avg)_Endo
• Myocardial/full wall deformation is assessed by performing
analysis of the whole ROI trace. Measurements derived
from myocardial deformation are suffixed Full, such as for
instance GPeakSysSL(Avg)_Full
It is possible to change the reference layer preference using the
Config screen
, see Figure 8-20.
NOTE: If attempting to reprocess an analysis using a different reference
layer a warning will be shown informing that the values in the
analysis will change.
AFI configuration
It is possible to configure some of the AFI controls to modify the
workflow slightly.
1. Press Utility/Config on the Touch panel, select the category
Meas/Text and the Advanced Quantification subgroup.
Select the AFI tab. The following parameters may be
adjusted:
•
Autoprocessing timeout
- The time the operator has to
keep trackball still before automatic start of tracking.
•
BE Mode
– Colormaps that shall be available for the
Bulls Eye.
•
BE Segment model
- Select the preferred Bulls Eye
standard (ASE/AFI, 17/18 segment models).
•
ROI Method
– Select whether fully automatic or 3-Click
ROI shall be the tool default.
•
YoYo
– When adjusting the ROI, select whether a
limited number of frames around the selected ROI
frame should be looped back and forth to ease ROI
adjustment.
•
Strain reference layer
– Select whether the strain values
shall be calculated based on endocardial or full wall
tracking.
•
AVC Stage mode
– Select whether to always open the
AVC Selection stage. If "Auto" is selected, upon analysis
of the APLAX view, the user will be taken to Results
stage after the ROI stage. "Auto" AVC or Event timing
will be used by default. It will still be possible for the user
to re-visit the AVC Selection stage to edit the chosen
AVC.
