Imaging of Shear Waves Induced by Lorentz Force in Soft Tissues [PDF]

, 2014
This study presents the first observation of elastic shear waves generated in soft solids using a dynamic electromagnetic field. The first and second experiments of this 5 study showed that Lorentz force can induce a displacement in a soft phantom and ...

Correlation-based full-waveform shear wave elastography

Physics in Medicine & Biology, 2023
Abstract Objective. With the ultimate goal of reconstructing 3D elasticity maps from ultrasound particle velocity measurements in a plane, we present in this paper a methodology of inverting for 2D elasticity maps from measurements on a single line. Approach.

Shear wave elastography of the saphenous nerve

Medicine, 2020
Abstract The purpose of this study is to study sonoelastographic features of the saphenous nerve. The study included 72 saphenous nerves in 36 healthy subjects. High resolution ultrasound and Shearwave elastography were used to evaluate the saphenous nerve.

Application of the novel estimation method by shear wave elastography using vibrator to human skeletal muscle

Scientific Reports, 2020
In recent years, non-invasive measurement of tissue stiffness (hardness) using ultrasound elastography has attracted considerable attention. It has been used to evaluate muscle stiffness in the fields of rehabilitation, sports, and orthopedics.

Posture-induced changes in peripheral nerve stiffness measured by ultrasound shear-wave elastography [PDF]

, 2017
Introduction: Peripheral nerves slide and stretch during limb movements. Changes in nerve stiffness associated with such movements have not been examined in detail but may be important in understanding movement-evoked pain in patients with a variety of ...

Lorentz force induced shear waves for magnetic resonance elastography applications

Scientific Reports, 2021
Quantitative mechanical properties of biological tissues can be mapped using the shear wave elastography technique. This technology has demonstrated a great potential in various organs but shows a limit due to wave attenuation in biological tissues.

Spring-damper equivalents of the fractional, poroelastic, and poroviscoelastic models for elastography

, 2017
In MR elastography it is common to use an elastic model for the tissue's response in order to properly interpret the results. More complex models such as viscoelastic, fractional viscoelastic, poroelastic, or poroviscoelastic ones are also used.
