Speckle tracking methods for ultrasonic elasticity imaging using short-time correlation
The results demonstrate that high resolution, high SNR strain estimates can be computed using small correlation kernels (on the order of the autocorrelation width of the ultrasound signal) and correlation filtering.

Reconstructive Elasticity Imaging
To uniquely image tissue elasticity, the Young’s modulus must be reconstructed from estimates of internal displacement and strain.
