Abstract

An ultrasonic diagnosis apparatus includes an ultrasonic probe. A transmitter supplies a transmission pulse to the ultrasonic probe to repeatedly transmit an ultrasonic wave to each of a plurality of scanning lines. A receiver receives echoes of the ultrasonic waves through the ultrasonic probe and obtaining a plurality of received signals for each of the plurality of scanning lines. A displacement estimating means estimates a relative change accompanying a tissue motion between received signals associated with each of scanning lines. A displacement correcting means corrects the received signals in accordance with the change detected by the displacement estimating means. A harmonic component extracting means extracts a harmonic component from the received signals corrected by the displacement correcting means. A display means generates an ultrasonic image on the basis of the harmonic component extracted by the harmonic component extracting means. A monitor displays the image generated by the display means.
