Five different geometries and four different fibrotic tissues were analyzed. The first data row represents the R ² between the real behavior curve and the resulting curve obtained with the second methodology. The last two rows show the cost function value between the ${\epsilon }_{rr}^{\mathit{IV\; US}}$ and ${\epsilon }_{rr}^{\mathit{iterated}}$ using the first approach (J _linear ) and the second one (J _non−linear ).
