Errors in linear elastic (top row) and Yeoh (middle and bottom rows) material parameter recovery over 8 runs. The performance of the current interface matching method (left column) is compared to inner and outer surface matching alone (middle column), and diameter matching (right column). Full interface matching outperforms surface matching and diameter matching in all cases, but the distinction is more pronounced for the higher-order Yeoh model and for the predominantly intramural materials (mixed and lipid tissue). The median errors (dashed horizontal lines) were greater for material parameters with lower assigned value magnitudes. Boxes extend from 25th to 75th percentiles; range bars extend to extrema.
