In the breast, prostate and other organs increased tissue stiffness is often associated with the presence of disease. While palpation remains widely used, it has limited sensitivity which is highly dependent upon the skill of the clinician. To overcome this and other limitations a variety of automated approaches have been developed in recent years ...

Digital pure shear-strain moiré patterns
Applied Optics, 1992A method of constructing digital shear-strain moiré patterns with pure shear-strain fringes is proposed here with the help of digital image processing techniques and moiré carrier patterns of rotation. This method is developed from a digital pure secondary moiré pattern method.

Determinants of left ventricular shear strain
American Journal of Physiology-Heart and Circulatory Physiology, 2009Mathematical models of cardiac mechanics can potentially be used to relate abnormal cardiac deformation, as measured noninvasively by ultrasound strain rate imaging or magnetic resonance tagging (MRT), to the underlying pathology. However, with current models, the correct prediction of wall shear strain has proven to be difficult, even for the normal ...

Resolution of axial shear strain elastography
Physics in Medicine and Biology, 2006The technique of mapping the local axial component of the shear strain due to quasi-static axial compression is defined as axial shear strain elastography. In this paper, the spatial resolution of axial shear strain elastography is investigated through simulations, using an elastically stiff cylindrical lesion embedded in a homogeneously softer ...

P1C-5 Shear Strain Imaging with Shear Deformation
2006 IEEE Ultrasonics Symposium, 2006In this paper we investigate the generation of shear strain elastograms induced using a lateral shear deformation. Simulation and experimental results demonstrate that the shear strain elastograms obtained under shear deformation exhibit significant differences between bounded and unbounded inclusion phantoms, when compared to shear strain images ...

Reduction of Shear Modulus at Small Strains in Simple Shear
Journal of Geotechnical and Geoenvironmental Engineering, 1997Cyclic tests were conducted to study the secant shear modulus, Gs, of two reconstituted sands and three laboratory-made clays at small cyclic shear-strain amplitudes γc≈ 0.0006%–0.02%. A recently developed direct simple shear device for small-strain testing was employed. The effects of cyclic strain amplitude (γc), type of soil and plasticity index (PI)
