Abstract
Improved methods of signal processing for generating estimates of tissue strain are presented. These techniques generally employ the frequency shifting of post-compression spectral data to determine a scaling factor which approximates the applied tissue strain. The scaling factor can be determined by finding the maximum correlation between the frequency shifted post-compression data to the pre-compression data and can also be determined by minimizing the variance of the ratio of such data. Correlation tracking and maximum correlation magnitude techniques for improving the results of elastography are also presented.
