Abstract
An ultrasonic diagnostic apparatus is provided with an ultrasonic probe that has at its end a low frequency ultrasonic transducer group and a high frequency ultrasonic transducer group, and a selection switch for selecting one of these transducer groups. According to the selection at the selection switch, a switching device of the ultrasonic probe connects either the low frequency ultrasonic transducer group or the high frequency ultrasonic transducer group to a multiplexer. The multiplexer selects from among ultrasonic transducers of the selected group ones to be driven at the same time, while shifting the driven transducers of the same group step by step.
