The Contrast Order: An Order-Based Image Quality Criterion for Nonlinear Beamformers
Dongwoon Hyun
Many modern ultrasound beamformers report improved image quality when evaluated using classical criteria like the contrast ratio and contrast-to-noise ratio, which are based on sum…

Ultrasound Autofocusing: Common Midpoint Phase Error Optimization via Differentiable Beamforming
Walter Simson, Louise Zhuang, Benjamin N. Frey +3
In ultrasound imaging, propagation of an acoustic wavefront through heterogeneous media causes phase aberrations that degrade the coherence of the reflected wavefront, leading to r…

Enhancing Ultrasound Molecular Imaging: Toward Real-Time RPCA-Based Filtering to Differentiate Bound and Free Microbubbles
Hoda S. Hashemi, Dongwoon Hyun, Nathan Nguyen +6
Ultrasound molecular imaging (UMI) is an advanced imaging modality that shows promise in detecting cancer at early stages. It uses microbubbles as contrast agents, which are functi…
