Ultrasonic diagnostic apparatus and method of generating ultrasonic image

Abstract

The invention provides an ultrasonic diagnostic apparatus that scans an object to be examined into which contrast medium bubbles are injected with ultrasonic waves to acquire an ultrasonic image of the object. The ultrasonic diagnostic apparatus includes an image data generating unit that generates a plurality of image data indicating information on the shape of an object to be examined on the basis of echo signals returning from the object, a setting unit that sets an interesting area which is smaller than the entire image area to first image data, which is reference image data, among the plurality of image data, a vector generating unit that compares at least one second image data different from the first image data among the plurality of image data with data in the interesting area to generate a motion vector indicating the motion between the first image data and the at least one second image data, an image correcting unit that corrects the blur of the first image data and the at least one second image data on the basis of the motion vector, and an image generating unit that generates a display image on the basis of the plurality of corrected image data.
