Gregg E Trahey

Gregg E. Trahey

Robert Plonsey Professor of Biomedical Engineering

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.
