We derive closed-form solutions for reverberant elastography in anisotropic elastic media by adapting the framework used in electromagnetic theory to treat transverse isotropic materials. Different sample-setup geometries are analyzed, highlighting their relevance for both optical coherence elastography (OCE) and ultrasound elastography (USE). Numerical simulations using finite elements are used to validate the proposed solutions in practical cases. OCE experiments are conducted in ex vivo…

Reverberant shear wave phase gradients for elastography

It is demonstrated that the reverberant phase gradient is shown to be proportional to the local value of wavenumber, providing the basis for adroit implementations of elastography from imaging systems that can map out the internal velocity or displacement of tissues during reverberant field excitations.

On the elasticity of transverse isotropic soft tissues (L).

The transverse isotropic model established for hexagonal crystals is revisited in the case of soft solids and relationships between elastic constants and Young's moduli are derived and validated on experimental data found in the literature.

Reverberant 3D optical coherence elastography maps the elasticity of individual corneal layers

Experiments in ex vivo porcine cornea at different intraocular pressures reveal that Rev3D-OCE enables the elastic characterization of single layers that matches the anatomical description of corneal layers with unprecedented contrast in the dynamic OCE field.

Shear elasticity estimation from surface wave: the time reversal approach.

In this work the shear elasticity of soft solids is measured from the surface wave speed estimation, and one advantage of the present approach is its low sound technology cost.
