Because errors in displacement and strain estimates depend on the magnitude of the induced strain, the strain signal-to-noise ratio (SNR) will be a function of the applied deformation. If deformation is applied at the body surface, it is difficult du

Using the incompressibility property of soft tissue, high quality lateral displacement distributions can be reconstructed from accurate axial displacement measurements and noisy lateral displacement estimates. Previous methods appropriate for small d

An elasticity microscope images tissue stiffness at fine resolution. Possible applications include dermatology, ophthalmology, pathology, and tissue engineering. In addition, if the resolution approaches cellular dimensions, then this system may be v

Evaluation of internal displacement and strain distributions in tissue under externally applied forces is a necessary step in elasticity imaging. To obtain a quantitative image of the elastic modulus, strain and displacement fields must be measured w

In ultrasound elasticity imaging, strain decorrelation is a major source of error in displacements estimated using correlation techniques. This error can be significantly decreased by reducing the correlation kernel. Additional gains in signal-to-noi

Quantitative strain images of tissue equivalent phantoms have been obtained for a number of conditions using Fourier-based speckle tracking methods. Experimental results demonstrate that a non-palpable inclusion with Young's modulus only 3 times grea

Ultrasound's dynamic and interactive (i.e., real-time) nature is it's major advantage compared to other imaging modalities. For elasticity imaging, real-time data capture provides an excellent foundation for retrospective data processing, including a

Diagnosing hemangioma-the most common benign vascular malformation in the liver-requires special and expensive imaging studies including nuclear medicine, magnetic resonance or CT scans. Routine ultrasound is suggestive but not diagnostic. In this pa
