Correlation between AIF and the total infarcted fraction for various infarction geometries. Correlation between AIF and the total infarcted fraction derived from the numerical ventricle model for different surrounding background levels (bg) and for the breathing direction tangential or perpendicular to the defect Equations 4 and 5 were used with the experimental parameters U
c = 0.55 and n = 9. The extremities of the error bars correspond to the minimal and maximal AIF obtained by varying the polar position of the defect versus the polar map segmentation. For graphical clarity, all points were simulated for different defect polar extensions.
