PROBLEM TO BE SOLVED: To provide an improvement technology improving reliability of Doppler information in an ultrasonic diagnostic apparatus.SOLUTION: In an ultrasonic diagnostic apparatus, reception signals are acquired along ultrasonic beams while cyclically moving the ultrasonic beams passing through a measurement region in the measurement region. A sampling processing part 20 utilizes a plurality of sampling sets whose time phases are shifted with each other and subjects the reception signals to sampling processing in each of the sampling sets over a plurality of time phases so as to acquire reception data arrays in each of the sampling sets. And thereby, Doppler information in the measurement region can be acquired on the basis of a plurality of reception data arrays corresponding to the plurality of sampling sets. |
