ABSTRACT:
High-resolution elastography employs a multiple-step process in which successively finer samplings of data and smaller areas of data are evaluated to provide increasingly accurate displacement measurements, wherein each displacement measurement guides the determination of corresponding regions of comparison used in the next displacement evaluation.
