Reverberant shear wave phase gradients for elastography
Physics in Medicine & Biology, 2021Abstract Reverberant shear wave fields are produced when multiple sources and multiple reflections establish a complex three-dimensional wave field within an organ. The expected values are assumed to be isotropic across all directions and the autocorrelation functions for velocity are expressed in terms of ...

Binary Pattern Color Doppler Shear Wave Elastography
2021 43rd Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2021Some studies suggested a correlation between tissue elasticity and diseases, such as Adhesive Capsulitis (AC) of the shoulder. One category of method to measure elasticity is by utilizing Doppler imaging. This paper discusses color Doppler shear wave elastography methods and demonstrated an experiment with biological tissue mimicking phantom.

Shear wave elastography for intracranial epidermoid tumors
Clinical Neurology and Neurosurgery, 2021Ultrasound elastography (USE) is a novel technique that assesses the mechanical properties of body tissues in real time. Based on elasticity measurements, USE enables the differentiation of tumor tissue from surrounding normal tissue.We aimed to evaluate an intraoperative SWE technique for differentiating tumor tissue (epidermoid cyst) from the ...

An Artifact in Supersonic Shear Wave Elastography
Ultrasound in Medicine & Biology, 2017Supersonic shear wave elastography is a novel ultrasound technology that allows objective evaluation of soft tissue stiffness. The purpose of this study is to report an artifact in supersonic shear wave elastography that may strongly affect the accuracy and quality of the measurement of soft tissue stiffness, and to step-by-step describe how the ...

Shear wave elastography in ophthalmic diagnosis
Journal Français d'Ophtalmologie, 2019Shear wave elastography (SWE) is a non-invasive diagnostic imaging technique that maps the elastic properties of tissues. This modality is being increasingly developed in other areas of medicine, offering a new type of high-quality ultrasound examination, since it increases specificity and thus improves diagnostic accuracy.

The study of new tissue mechanical properties such as shear nonlinearity could lead to better tissue characterization and clinical diagnosis. This work proposes a method combining static elastography and shear wave elastography to derive the nonlinear shear modulus by applying the acoustoelasticity theory in quasi-incompressible soft solids.

Shear Wave Imaging of Breast Tissue by Color Doppler Shear Wave Elastography
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2017Shear wave elastography is a distinctive method to access the viscoelastic characteristic of the soft tissue that is difficult to obtain by other imaging modalities. This paper proposes a novel shear wave elastography [color Doppler shear wave imaging (CD SWI)] for breast tissue.
