In situ ultrasound imaging of shear shock waves in the porcine brain

JOURNAL OF BIOMECHANICS, 134.

By: S. Chandrasekaran n, F. Santibanez  n, B. Tripathi*, R. DeRuiter n, R. Bruegge n & G. Pinton n

author keywords: Ultrasound imaging; RF tracking; Motion tracking; Shear waves; Shock waves
MeSH headings : Animals; Brain / diagnostic imaging; Brain Injuries, Traumatic; Elasticity Imaging Techniques / methods; Head; Motion; Phantoms, Imaging; Swine; Ultrasonography / methods
TL;DR: The experimental velocity, acceleration, and strain-rate waveforms in brain for the monochromatic impact are shown to be in excellent agreement with theoretical predictions from a custom higher-order finite volume method hence demonstrating the capabilities to measure rapid brain motion despite strong acoustical reverberations from the porcine skull.

2019 journal article

Piecewise parabolic method for propagation of shear shock waves in relaxing soft solids: One-dimensional case

INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN BIOMEDICAL ENGINEERING, 35(5).

By: B. Tripathi n, D. Espindola  n & G. Pinton n

author keywords: piecewise parabolic method; relaxation mechanisms; shear shock waves; traumatic brain injury
