Using the incompressibility property of soft tissue, lateral displacements can be reconstructed from axial strain measurements. Results of simulations and experiments on gelatin-based tissue equivalent phantoms are compared with theoretical displacem

In elasticity imaging, a surface deformation is applied to an object using small pistons, and the resulting induced strains in the interior of the object are measured using ultrasonic imaging. Two important problems are considered: (1) the forward pr

In elasticity imaging a surface deformation is applied to the object and the resulting induced strains in the interior of the object are measured using ultrasound. Two important problems are considered: (1) the inverse problem of determining the elas

The problem of estimating sinusoidal frequencies at low signal-to-noise ratios (SNRs) is considered. The principal component (PC) method has a threshold SNR of about 7 dB. A lowering of this threshold can be achieved if the PC method is cascaded with

An algorithm for estimating the frequencies of two sinusoids in white noise is presented. The method uses the eigenvectors of the estimated autocorrelation matrix (ACM) to yield the signal vectors. Since the signal and the eigenvectors span the same
