Abstract
An improvement to a pulse-echo ultrasonic-imaging system employing an acoustic focusing device occupying a fixed aperture to both illuminate internal structure of a visually opaque object with a scanning focused beam of ultrasonic energy and for returning a reflected signal portion of the scanning focused beam passed therethrough for detection. The improvement accomplishes real time scanning by scanning all of the image samples within a group of such samples in a time period not much longer, at most, than the round-trip travel time delay of the focused beam required to receive the reflected signal portion of only a single sample for detection. By way of example, this may be accomplished by a phased-array transducer arrangement.
