<p>PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic device which can remove residual multiple artifacts.SOLUTION: An ultrasonic diagnostic device includes a transmission and reception part 11, a signal processing part 12, an image generation part 13, and a control part 16. The transmission and reception part 11 executes a plurality of sets of ultrasonic transmission and reception with a plurality of times of ultrasonic transmission and reception on the same scan line as a unit on the scan line by changing transmission conditions to generate reception signal groups for the plurality of sets. The signal processing part 12 synthesizes the reception signal groups in each of the plurality of sets to generate a plurality of synthesis signals corresponding to the plurality of sets respectively. The image generation part 13 generates ultrasonic image data by using the plurality of synthesis signals. The control part 16 controls the order of ultrasonic transmission and reception executed by the transmission and reception part 11 so that the transmission conditions of transmission immediately before each of the plurality of times of transmission corresponding to the plurality of reception signals in one set synthesized by the signal processing part become the same and phase polarities differ from each other.</p> |
