An ultrasonic diagnostic apparatus comprises a driving unit, a nonlinear component extracting unit, a first image data generating unit, a second image data generating unit and a control unit. The driving unit drives an ultrasonic transducer to transmit an ultrasonic wave to a subject. The nonlinear component extracting unit extracts a nonlinear component corresponding to the ultrasonic wave from a reception signal received by the ultrasonic transducer. The first image data generating unit generates a first image data based on the nonlinear component. The second image data generating unit generates a second image data based on the reception signal. The control unit arbitrarily distributes a sound output for transmission in a definite period of time to a first ultrasonic transmission for generating the first image data and a second ultrasonic transmission for generating the second image data.
