Nearly-incompressible transverse isotropy (NITI) of cornea elasticity: model and experiments with acoustic micro-tapping OCE.
John J. Pitre,Mitchell A. Kirby,David S. Li,Tueng T. Shen,Ruikang K. Wang,Matthew O'Donnell,Ivan Pelivanov +6 more
TL;DR: In this article, a nearly-incompressible transversely isotropic (NITI) model depicting corneal biomechanics was proposed, showing that the cornea must be described by at least two shear moduli, contrary to current single-modulus models.
Computational Fluid Dynamics Modeling of the Burr Orbital Motion in Rotational Atherectomy with Particle Image Velocimetry Validation
TL;DR: Utilizing the small burr orbital motion has the potential to be an improved RA technique and is developed to simulate the burr motion and study the fluid flow and force in RA.

TL;DR: In this article, a non-contact and non-invasive method to image and characterize skin elastic anisotropy was proposed, which combines acoustic micro-tapping optical coherence elastography (AmT-OCE) with a nearly incompressible transversely isotropic (NITI) model to quantify skin's elastic moduli.
Design and Testing of a Single-Element Ultrasound Viscoelastography System for Point-of-Care Edema Quantification

TL;DR: This benchtop validation study tested the feasibility of using the UVE system by measuring the mechanical properties of a tissue-mimicking material under large strains, and generated depth-dependent creep curves and vis coelastic parameter maps of time constants and elastic moduli for the Kelvin model of viscoelasticity.

TL;DR: A method for quantifying the impact of compression on the electrical properties of tissue by measuring stress-induced changes in bioimpedance (BIS) and demonstrating a temporal quantification of viscoelastic properties using a vis coelastic phantom tissue model is developed.
