TASK-BASED ADAPTIVE TRANSMIT BEAMFORMING FOR EFFICIENT ULTRASOUND QUANTIFICATION

ICASSP 2026poster

Wireless and wearable ultrasound devices promise to enable continuous ultrasound monitoring, but power consumption and data throughput remain critical challenges. Reducing the number of transmit events per second directly impacts both. We propose a task-based adaptive transmit beamforming method, fo…

Sequential Posterior Sampling with Diffusion Models

Tristan S. W. Stevens, Oisín Nolan, Jean-Luc Robert, Ruud J. G. van Sloun

ICASSP 2025accepted

Diffusion models have quickly risen in popularity for their ability to model complex distributions and perform effective posterior sampling. Unfortunately, the iterative nature of these generative models makes them computationally expensive and unsuitable for real-time sequential inverse problems su…
