Automated Function Imaging
Automated Function Imaging (AFI) is a decision support tool for
regional assessment of the LV systolic function. AFI is a tool
derived from the 2D Strain, which tracks and calculates the
myocardial tissue deformation based on feature tracking on 2D
grey scale loops.
AFI is used to compute local and global tissue deformations in
the myocardium.
The purpose of AFI is to provide the user with a decision
support tool when reporting myocardial function.
AFI is performed on apical views in the following order: apical
long-axis, 4-chamber and 2-chamber view, following an on
screen guided workflow (Figure 7-10).
The result is presented as a Bulls-Eye display showing color
coded and numerical values for peak systolic longitudinal
strain. All values are stored to the worksheet. In addition,
Global Strain for each view, Average Global Strain for the whole
LV, and the Aortic Valve Closure time used in the analysis are
stored to the worksheet.
