Table 7.

Linear elastic fitted arterial wall and plaque SEF coefficients for heterogeneous and homogeneous wall structure. Also shown are the mean percentage difference between experimental and computational vessel minimum and maximum diameters calculated at each image slice (Geometry Difference (%)) and the standard deviations of the error values calculated at each slice (% Diff StDev). Additionally the percentage difference between experimental and computational vessel minimum and maximum diameters at each slice for the median fitted parameters is also given (Geometry Difference (median fit, %)) and the standard deviation of the error values at each slice for the median fitted parameters (Geometry Difference StDev (median fit, %) ).
