Overview


My laboratory develops and evaluates novel ultrasonic imaging methods. Current projects involve high resolutioon imaging of the breast and mechanical characterization of the breast and cardiovascular system. We conduct phantom, animal, ex vivo and in vivo trials. Current clinical trials involve imaging of soft and hard vascular plaques and mecahnical imaging of breast lesions.

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 Cite

Spatial 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 Cite

In Vivo Demonstration of a Real-Time Temporal SNR Acoustic Output Adjustment Method.

Journal Article IEEE Trans Ultrason Ferroelectr Freq 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 Link to item Cite
