Paper Abstract

Real-time 3-D ultrasonic imaging is not practical using conventional steered focused beam techniques. However, defocused transmitted pulses, combined with an image reconstruction approach related to computed tomography, make high quality real-time 3-D ultrasonic imaging feasible. `Three-dimensional Real Time Ultrasonic Imaging using Ellipsoidal Backprojection' (F. Anderson, SPIE's Medical Imaging V, 1991) contained point images produced with 32 receivers and 16 transmitters (32 X 16). This paper shows images produced by much larger arrays (e.g., 256 X 256), and resulting lower sidelobe levels.
