1. An ultrasonic diagnostic apparatus for repeatedly performing a scan of transmitting ultrasonic beams to an image capture region in a subject and receiving an ultrasonic echo reflected from the image capture region, in a scan direction so as to correspond to the image capture region and, after that, on the basis of sound ray data obtained by performing the scans, generating an ultrasonic diagnosis image of the image capture region, comprising: an image correcting unit for performing a correcting process on the ultrasonic diagnosis image, wherein the image correcting unit executes an extracting process for extracting from the ultrasonic diagnosis image a sound ray vector image extending in a sound ray direction in which the ultrasonic beam is transmitted in the ultrasonic diagnosis image, and thereafter, performs the correcting process so as to eliminate the sound ray vector image extracted by the extracting process from the ultrasonic diagnosis image.
