An Iterative Method for Estimating Nonlinear Elastic Constants of Tumor in Soft Tissue from Approximate Displacement Measurements
Figure 4
(a) Two US images of the phantom and (b) the estimated axial displacement and strain fields. The recorded RF signals of the elastography phantom (by Rivaz et al. [68, 69]), before/after it was compressed, have been used to create the US images and compute the axial displacement and strain fields.
