Method for estimating and imaging of transverse displacements, transverse strains and strain ratios |
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 high precision lateral estimation, the method of the present invention can produce quality lateral-elastograms that display the lateral component of the strain tensor. These higher precision lateral displacement estimates also allow a finer correction for the lateral decorrelation that corrupts the axial estimation. The method of the present invention may be employed to divide the lateral-elastogram by the axial-elastogram on a pixel-by-pixel basis, in order to produce a new image that displays the distribution of Poisson's ratios in the tissue.
