A control device of an ultrasonic diagnostic apparatus includes a detector that detects a Doppler signal from a reception signal based on a reflected ultrasonic wave reflected on an internal portion of a subject, and a clutter component reducer that acquires a frequency spectrum based on the Doppler signal and reduces a clutter component from the acquired frequency spectrum based on symmetry of the clutter component which is distinguished from asymmetry of a blood flow component in the acquired frequency spectrum.
