Biography

Stan Okrasinski completed his undergraduate work at the University of North Carolina while working in an ultrasound lab. He constructed and programmed an ultrasound scanner using the swept-scan method with a single-element transducer. At the same time, he wrote an undergraduate thesis titled Classifying the Diameter of Ultrasound Contrast Agents, which studied the acoustic backscatter of ultrasound contrast agents. His research interests include cardiac ultrasound and torsional dynamics of the heart.
