Clutter-Generating Phantom Material. Part I: Development of a Tunable, Acoustic Clutter-Generating Layer for Use With Ultrasound Tissue-Mimicking Phantoms.
Journal Article Ultrasound in medicine & biology · May 2025 ObjectiveAcoustic clutter is a major source of image degradation for in vivo ultrasound imaging. However, clutter is often not represented in laboratory testing of ultrasound equipment. A phantom material is proposed that can be used to add calibr ... Full text CiteSpatial Ambiguity Correction in Coherence-Based Average Sound Speed Estimation.
Journal Article IEEE transactions on ultrasonics, ferroelectrics, and frequency control · October 2024 Sound speed estimation can potentially correct the focusing errors in medical ultrasound. Maximizing the echo spatial coherence as a function of beamforming sound speed is a known technique to estimate the average sound speed. However, beamformation with c ... Full text CiteIn Vivo Demonstration of a Real-Time Temporal SNR Acoustic Output Adjustment Method.
Journal Article IEEE transactions on ultrasonics, ferroelectrics, and frequency control · August 2024 This work proposes a novel method of temporal signal-to-noise ratio (SNR)-guided adaptive acoustic output adjustment and demonstrates this approach during in vivo fetal imaging. Acoustic output adjustment is currently the responsibility of sonographers, bu ... Full text CiteRecent Grants
