PROBLEM TO BE SOLVED: To provide effective data for the diagnosis by removing motion artifacts caused by the motion of a tissue, especially the heart, etc., by an ultrasonic diagnostic apparatus for producing an image by processing plural received signals with different rates and extracting a harmonic component. SOLUTION: This ultrasonic diagnostic apparatus has a displacement estimating part 19 for repeatedly transmitting ultrasonic waves to each of plural scanning lines and detecting relative changes corresponding to the motion of a tissue between plural received signals obtained by receiving the echoes for the plural scanning lines, and a displacement correcting part 20 for correcting received signals according to the changes detected by the displacement estimating part 19. By processing the corrected received signals, an ultrasonic image is produced and the image is displayed. |
