Alignment error results for the B-mode (a, b) and strain imaging (c, d) modalities for the organ-like phantom (n = 178 for B-mode, n = 83 for strain). The position of tumor borders in each modality was evaluated in terms of modified Hausdorff distance to the co-aligned computed tomography borders (a, c), as well as the distance between the centroid of the ultrasound tumor and the co-planar CT tumor border (b, d). The edges of the boxes are the 25th and 75th percentiles, and the whiskers extend to the most extreme data points not considered as outliers.
