ABSTRACT:
In a method for controlling ultrasonic waves wherein a plurality of elements constituting a phased array ultrasonic transducer are driven with desired delay times, the improvement therein comprising the fact that when values obtained by quantizing the delay times by a predetermined time are different between the adjacent elements, the ultrasonic waves are radiated with a delay of time corresponding to the difference.
