In a cylindrical transducer constructed of a plurality of ultrasonic transducer arrays arranged in a circular form, the ultrasonic transducer arrays is divided into a plurality of groups, and tilt angles of transmitting and receiving beams are controlled to compensate for swing motions of the cylindrical transducer depending on which group the individual ultrasonic transducer arrays belong. Provided that the uncompensated tilt angle of the beam is a and the angle of inclination of the cylindrical transducer in a particular direction is b, the tilt angle of the beam formed by a transducer array in the inclining direction should be adjusted to α−β and the tilt angle of the beam formed by a transducer array in the opposite direction should be adjusted to α+β.
A method of controlling the direction of a transmitting beam and a receiving beam formed by a cylindrical transducer which is constructed of a plurality of ultrasonic transducer arrays arranged in a circular form, said method comprising the steps of:
An apparatus for controlling the direction of a transmitting beam and a receiving beam formed by a cylindrical transducer which is constructed of a plurality of ultrasonic transducer arrays arranged in a circular form, the ultrasonic transducer arrays being divided into a plurality of groups, said apparatus comprising:
