Patient-Adaptive Echocardiography using Cognitive Ultrasound
Wessel L. van Nierop, OisÃn Nolan, Tristan S. W. Stevens +1
Focused transmits are the most commonly used transmit strategy for echocardiograms, but suffer from relatively low frame rates, and in 3D, even lower volume rates. Fast imaging bas…
Nuclear Diffusion Models for Low-Rank Background Suppression in Videos
Tristan S. W. Stevens, OisÃn Nolan, Jean-Luc Robert +1
Video sequences often contain structured noise and background artifacts that obscure dynamic content, posing challenges for accurate analysis and restoration. Robust principal comp…
Task-Based Adaptive Transmit Beamforming for Efficient Ultrasound Quantification
OisÃn Nolan, Wessel L. van Nierop, Louis D. van Harten +2
Wireless and wearable ultrasound devices promise to enable continuous ultrasound monitoring, but power consumption and data throughput remain critical challenges. Reducing the numb…
High Volume Rate 3D Ultrasound Reconstruction with Diffusion Models
Tristan S. W. Stevens, OisÃn Nolan, Oudom Somphone +2
Three-dimensional ultrasound enables real-time volumetric visualization of anatomical structures. Unlike traditional 2D ultrasound, 3D imaging reduces reliance on precise probe ori…
Semantic Diffusion Posterior Sampling for Cardiac Ultrasound Dehazing
Tristan S. W. Stevens, OisÃn Nolan, Ruud J. G. van Sloun
Echocardiography plays a central role in cardiac imaging, offering dynamic views of the heart that are essential for diagnosis and monitoring. However, image quality can be signifi…
Active Diffusion Subsampling
Oisin Nolan, Tristan S. W. Stevens, Wessel L. van Nierop +1
Subsampling is commonly used to mitigate costs associated with data acquisition, such as time or energy requirements, motivating the development of algorithms for estimating the fu…
