An atlas of the heterogeneous viscoelastic brain with local power-law attenuation synthesised using Prony-series
Oisin Morrison, Michel Destrade, Bharat B. Tripathi
This review addresses the acute need to acknowledge the mechanical heterogeneity of brain matter and to accurately calibrate its local viscoelastic material properties accordingly.…
In situ ultrasound imaging of shear shock waves in the porcine brain
Sandhya Chandrasekaran, Francisco Santibanez, Bharat B. Tripathi +2
Using high frame-rate ultrasound and high sensitivity motion tracking, we recently showed that shear waves sent to the ex vivo porcine brain develop into shear shock waves with des…
Super-resolved shear shock focusing in the human head
Bharat B. Tripathi, Sandhya Chandrasekaran, Gianmarco Pinton
Shear shocks, which exist in a completely different regime from compressional shocks, were recently observed in the brain. These low phase speed ( 2 m/s) high Mach number…
Modeling ultrasound propagation in the moving brain: applications to shear shock waves and traumatic brain injury
Sandhya Chandrasekaran, Bharat B. Tripathi, David Espíndola +1
Traumatic brain injury studies on the living human brain are experimentally infeasible. We present a simulation approach that models ultrasound propagation in the human brain while…
