Paper Abstract

A new digital beam-forming technique for the ultrasound imaging is proposed. This technique is based on the holographic beam-forming and the signal-decomposition using uncorrelated pulses, and it permits high speed data acquisition with simple hardware. Some algorithm for the decomposition and beam-forming is described. The ability of the method is discussed through the analysis of the point spread function simulated by the computer, and an experimental system using an airborne sensor array is shown.
