ABSTRACT:
Each of a plurality of transducers comprising a transducer array of an ultrasonic probe are sequentially driven, and the echo signals obtained from each of the transducers are stored in memory as complex data, following A/D conversion, quadrature detection, and the like. These complex data are read following a wave-front locus which converges on the focal point set as an observation point, and further the vector directions of each of the complex data are subjected to phase correction and synthesized, thus obtaining an ultrasonic image with high resolution.
