The invention provides an ultrasonic diagnostic apparatus and an ultrasonic diagnostic image generating method realizing improvement in picture quality to thereby improve diagnosis efficiency in a diagnosis using images. An extracting process of extracting a sound ray vector image extending in a sound ray direction in which an ultrasonic beam is transmitted in an ultrasonic diagnosis image from the ultrasonic diagnosis image is performed. After that, a correcting process is performed so as to eliminate the sound ray vector image extracted by the extracting process from the ultrasonic diagnosis image.
