PROBLEM TO BE SOLVED: To accurately acquire the flow velocity and the flow direction of a subject such as a blood flow. SOLUTION: An ultrasonic diagnostic apparatus sends an ultrasonic multibeam by an ultrasonic probe 10, and acquires the blood flow velocity f<SB>0</SB>, the azimuthθ, and the elevationϕof the specimen 13 such as a blood flow as three-dimensional fluid information in a range gate RG by a three-dimensional information acquisition section 21 on the basis of Doppler signals output from the ultrasonic probe 10.
