Plane Wave Elastography: A Frequency-Domain Ultrasound Shear Wave Elastography Approach

no code implementations8 Dec 2020 Reza Khodayi-mehr, Matthew W. Urban, Michael M. Zavlanos, Wilkins Aquino

Currently, commercial methods for SWE rely on directional filtering based on the prior knowledge of the wave propagation direction, to remove complicated wave patterns formed due to reflection and refraction.

Adaptive particle-based approximations of the Gibbs posterior for inverse problems

no code implementations2 Jul 2019 Zilong Zou, Sayan Mukherjee, Harbir Antil, Wilkins Aquino

To manage the computational cost of propagating increasing numbers of particles through the loss function, we employ a recently developed local reduced basis method to build an efficient surrogate loss function that is used in the Gibbs update formula in place of the true loss.
