ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
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 transverse estimation, the method of the present invention can produce quality transverse-elastograms that display the transverse component of the strain tensor. These higher precision transverse displacement estimates also allow a finer correction for the transverse decorrelation that corrupts the axial estimation. The method of the present invention may be employed to divide the transverse-elastogram by the axial-elastogram on a pixel-by-pixel basis, in order to produce a new image that displays the distribution of strain ratios in the tissue.
