PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic device which stably and efficiently receives an echo from a contrast medium by giving a small amount of the contrast medium, and then, diagnoses the movement of a blood stream more minutely. SOLUTION: Image information for a portion, which hardly comprises contrast medium information and amounts n-1 sheets, is subtracted from additional information which is obtained by adding multiple (e.g. n-1 sheets) multi-shot image groups comprising contrast medium information. Image information based on the whole contrast medium existing on one scanning screen is obtained in terms of an image processing.
