A Probe, Not an Echo Non-Invasive and Safe, a New USC System Images and Differentiates Soft Tissue With Unprecedented Detail and PrecisionFriday, March 25, 2005 — Researchers at the University of Southern California's Viterbi School of Engineering have successfully demonstrated a novel “High-resolution Ultrasonic Transmission Tomography” (HUTT) system fthat offers 3D images of soft tissue that are superior to those produced by existing commercial X-ray, ultrasound or MRI units. Vasilis Marmarelis, a professor of biomedical engineering at the Viterbi School, presented HUTT images of animal organ tissue in San Diego at the 28th International Acoustical Imaging Symposium on March 21st....
