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…
