We’re excited to share new results from Mostafa and collaborators, presented at IEEE IUS 2025, demonstrating a major step forward in contrast-free super-resolution ultrasound imaging (SURE) for abdominal organs. While SURE can visualize microvascular structure and flow without contrast agents in just a few seconds, motion from breathing and organ movement has posed a challenge for transcutaneous imaging. In this work, the team introduced a dropped-frame method—using transverse oscillation (TO) to automatically remove motion-affected frames—combined with motion compensation and erythrocyte tracking. Applied to rat liver and kidney imaging, this approach produced clearer microvascular density and velocity maps than both traditional power Doppler and standard SURE methods, enabling accurate flow direction and velocity estimation even under significant motion. This advancement brings SURE imaging closer to reliable, real-time use in non-invasive abdominal diagnostics.
