Abstract

We propose a new digital beamforming algorithm using an interpolation filter in ultrasonic imaging systems. We compared the performances of the proposed algorithm to those of the conventional digital bemforming algorisms, post-beamformer and phase rotation beamformer, by a computer simulation and experiments. The results show that the proposed algorithm has better performance than the others.
