摘要: The present invention is directed toward a new method that combines interpolation between neighboring A-lines with cross-correlation for high precision estimation of the transverse displacement. Due to this lateral estimation, can produce quality lateral-elastograms display component strain tensor. These higher displacement estimates also allow finer correction decorrelation corrupts axial estimation. may be employed divide lateral-elastogram by axial-elastogram on pixel-by-pixel basis, in order image displays distribution Poisson's ratios tissue.
