Lens-Aware Differentiable Beamforming for In Vivo Distributed Aberration Correction with Curvilinear Transducers
Benjamin N. Frey, Robin van Velzen, Hoda S. Hashemi +7
We previously introduced ultrasound autofocusing, an iterative model-based aberration correction technique that estimates local sound speed and incorporates it into beamforming to…

A Wavefield Correlation Approach to Improve Sound Speed Estimation in Ultrasound Autofocusing
Louise Zhuang, Samuel Beuret, Ben Frey +4
In pulse-echo ultrasound, aberration often degrades image quality when beamforming does not account for wavefront distortions. To address this issue, local sound speed estimators h…
