Ma. Lubinski et al., LATERAL DISPLACEMENT ESTIMATION USING TISSUE INCOMPRESSIBILITY, IEEE transactions on ultrasonics, ferroelectrics, and frequency control, 43(2), 1996, pp. 247-256
Using the incompressibility property of soft tissue, lateral displacem
ents can be reconstructed from axial strain measurements, Results of s
imulations and experiments on gelatin-based tissue equivalent phantoms
are compared with theoretical displacements, as well as estimates der
ived from traditional speckle tracking, Incompressibility processing g
reatly improves the accuracy and signal-to-noise ratio (SNR) of latera
l displacement measurements compared with more traditional speckle tra
cking.
