2-D Bayesian Displacement Estimation Improves Contrast-to-Noise/Resolution Trade-off in Shear Wave Elasticity Imaging

Ultrasonic thermometry by a localized measurement of the longitudinal wave velocity using sound field information

“…In [20] "time reversal" algorithms reduce the decorrelation of the shear wave signal, but the proposed algorithm only works if the source position is known and the tissue expansion due to heating is negligible. In [21], [22], [23], [24], [25], it is stated that a main source of error is the uncertainty of the tracking position. Corrections are attempted with a-priori information [25] or calibration of the tracking position [24].…”
