Dynamic elastography, whether based on magnetic resonance, ultrasound, or optical
modalities, attempts to reconstruct quantitative maps of the viscoelastic properties of …

Developing methods for the non-invasive characterization of the mechanics of
musculoskeletal tissues is an ongoing research focus in biomechanics. Often, these …

Acoustoelasticity theory describes propagation of shear waves in uniaxially stressed
medium and allows the retrieval of nonlinear elastic coefficients of tissues. In transverse …

Assessing material properties from observations of shear wave propagation following an
acoustic radiation force impulse (ARFI) excitation is difficult in anisotropic materials because …

The goal of the study was to investigate the quantitative impact of region of interest (ROI),
software choice, muscle fiber orientation and preload tension on shear wave velocity (SWV) …

Currently, dynamic elastography techniques estimate the linear elastic shear modulus of
different body tissues. New methods that investigate other properties of soft tissues such as …

Objective. The aim of this study is to validate the estimation of the nonlinear shear modulus
($ A $) from the acoustoelasticity theory with two experimental methods, ultrasound (US) …

Shear wave elastography (SWE) techniques have received substantial attention in recent
years. Strong experimental data in SWE suggest that shear wave speed changes …

Tissue nonlinearity is conventionally measured in shear wave elastography by studying the
change in wave speed caused by the tissue deformation, generally known as the …

Renal anisotropy is a complex property of the kidney and often poses a challenge in
obtaining consistent measurements when using shear wave elastography to detect chronic …
