Strain and Elastic Modulus01:15

Strain and Elastic Modulus

9.2K
The quantity that describes the deformation of a body under stress is known as strain. Strain is given as a fractional change in either length, volume, or geometry under tensile, volume (also known as bulk), or shear stress, respectively, and is a dimensionless quantity. The strain experienced by a body under tensile or compressive stress is called tensile or compressive strain, respectively. In contrast, the strain experienced under bulk stress and shear stress is known as volume and shear...

Relation between Poisson's ratio, Modulus of Elasticity and Modulus of Rigidity01:15

Relation between Poisson's ratio, Modulus of Elasticity and Modulus of Rigidity

660
Deformation occurs in axial and transverse directions when an axial load is applied to a slender bar. This deformation impacts the cubic element within the bar, transforming it into either a rectangular parallelepiped or a rhombus, contingent on its orientation. This transformation process induces shearing strain. Axial loading elicits both shearing and normal strains. Applying an axial load instigates equal normal and shearing stresses on elements oriented at a 45° angle to the load axis.

Area of Science:

  • Biomedical Engineering
  • Medical Imaging
  • Rheology

Background:

  • Current ultrasound elastography estimates tissue elasticity using shear wave speed, assuming a purely elastic model.
  • Accurate rheological characterization requires estimating both shear wave speed and attenuation to determine storage (G') and loss (G″) moduli.
  • Acoustic radiation force-based elastography generates non-plane shear waves, necessitating diffraction correction for attenuation estimation.

Purpose of the Study:

  • To numerically and experimentally validate the cylindrical wave approximation for correcting shear wave attenuation in elastography.
  • To apply this correction to generate images of storage (G') and loss (G″) moduli in viscoelastic media.
  • To assess the feasibility of this corrected method for in vivo human liver imaging.

Main Methods:

  • Numerical simulations using anisotropic and viscoelastic Green's functions to assess cylindrical approximation validity.
  • Transient elastography with plane shear waves (vibrating plate) and Supersonic Shear Imaging (SSI) with acoustic radiation force.
  • Ultrafast ultrasound to track shear wave propagation, recovering velocity and attenuation from phase and amplitude decay.
  • Application of cylindrical wave approximation for diffraction correction in SSI experiments.

Main Results:

  • Numerical and experimental results confirm the validity of the cylindrical approximation for shear wave attenuation assessment.
  • The corrected method successfully generated G' and G″ images in heterogeneous phantoms.
  • A preliminary in vivo feasibility study in the human liver demonstrated potential clinical application.

Conclusions:

  • The cylindrical wave approximation provides a valid correction for shear wave attenuation in elastography.
  • This improved attenuation estimation allows for more comprehensive rheological characterization of tissues.
  • The method shows promise for enhanced noninvasive diagnosis through advanced ultrasound elastography.
