Abstract
An ultrasonic diagnostic apparatus of an embodiment includes an ultrasonic probe and processing circuitry. The ultrasonic probe repeatedly performs scanning in which a plane wave or a diffused wave is continuously transmitted a plurality of times in the same direction in a plurality of directions. The processing circuitry performs processing of applying a moving target indicator (MTI) filter to an unequal interval data sequence in the same direction obtained by the scanning and extracting a blood flow signal in each of the plurality of directions, performs processing of generating an autocorrelation signal by performing an autocorrelation operation on a plurality of blood flow signals in the same direction for each of the directions, and estimates a velocity value of blood flow on the basis of a complex signal generated by performing complex addition of a plurality of autocorrelation signals generated for the plurality of directions.
