PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic apparatus in which noise by clutter components is suppressed, with blood stream more clearly displayed.SOLUTION: An ultrasonic diagnostic apparatus includes: an MTI filter 152 that attenuates clutter components in receiving signals; a pre-attenuation correlation arithmetic part 156 that determines a dispersion value of velocity at each point from the pre-attenuation receiving signal of the clutter components in the MTI filter; a post-attenuation correlation arithmetic part 153 that determines an index of blood stream at each point from the post-attenuation signal in the MTI filter; an image display part 16 for displaying an image indicating the blood stream; and a display control part 154 that displays the determined index after replacing it with an index indicating no blood stream, with reference to the points in which, of each point, the dispersion value determined by the pre-attenuation correlation arithmetic part coincides with blood stream non-display conditions containing dispersion conditions falling below a first threshold value. |
