ABSTRACT:
An electronic scanning apparatus ultrasonic imaging adapted to converge or deflect an ultrasonic beam by controlling the amplitude and phase of the vibration of each transducer in a transducer array consisting of a plurality of regularly-arranged transducers, and adapted to move the ultrasonic beam by selecting from all of the transducers constituting the transducer array at least one transducer forming a transmitting and receiving aperture. The apparatus includes bidirectional transmitter-receivers connected to the transducers constituting the transducer array, a first switch unit for selecting the bidirectional transmitter-receivers to form a transmitting and receiving aperture by connecting signal lines to the bidirectional transmitter-receivers, a second switch unit for connecting together the signal lines connected to the transducers which are in positions symmetrical with respect to the center of the transmitting and receiving aperture, and a transmitting and receiving beam former for phasing a plurality of transmitting signals and a plurality of receiving signals.
