Three-dimensional ultrasound probes poised to advance minimally invasive surgery

Three-dimensional ultrasound probes built by researchers at Duke's Pratt School of Engineering have imaged the beating hearts of dogs. The engineers said their demonstration showed that the probes could give surgeons a better view during human endoscopic surgeries in which operations are performed through tiny "keyhole" incisions.
