Enhanced Ultrasound Imaging Princeton Docket # 15-3096-1Researchers at Princeton University, Department of Electrical Engineering, have proposed a method to improve ultrasound image quality. Ultrasound operates like radar, with a probe beam sent to the object and an echo recorded. 2D and 3D images are then built up point-by-point in a scanning fashion. In many cases, however,...
