ABSTRACT:
A method and apparatus for ultrasonically producing 3-dimensional images in real time, wherein a device transmits an ultrasonic wave toward a solid bearing angle obtained by dividing into multiple portions a solid bearing angle subtended by a sonic field to be examined, and receives echoes therefrom, with the transmitted waves being sequential and the received echoes being concurrent multiple waves from each small solid angle, and a device for producing the 3-dimensional images by range gating the received echo signals in the depth direction of the sonic field being examined and then producing direct vision images in the direction of the transmitted ultrasonic waves based on the echo signals, wherein the range gated signals are quadrature detected in one embodiment and/or are subjected to 2-dimensional Fourier transformation in another embodiment.
