Table 1.

Median and interquartile ranges (IQR) of the modulus reconstruction of the three vessels based on finite element modeling (FEM) and simulations. The median and IQR of the absolute differences between the input and output displacement fields are reported also.

(a) = concentric homogeneous vessel; (b) = eccentric homogeneous vessel; (c)_in = inner layer heterogeneous vessel; (c)_out = outer layer heterogeneous vessel,

^°

= single-angle,

= with compounding.

= No differentiation between the two layers of the heterogeneous vessel.
