Evaluation of a material parameter extraction algorithm using MRI-based displacement measurements

The performance of an inversion algorithm is investigated when applied to measured displacement data for a determination of the material parameters /sup /spl lambda/+2/spl mu///sub /spl rho// (longitudinal wave velocity squared) and /sup /spl mu///sub /spl rho// (shear wave velocity squared) through...
