PROBLEM TO BE SOLVED: To provide an improved technology for correcting dislocation of a contrast image. SOLUTION: A pattern matching part calculates a moving distance between time phases of an image part corresponding to its ROI34 with respective ROI34 based on image data of a B mode image 30 formed over a plurality of time phases. When the moving distance of the two ROI34 is successively calculated with respective time phases, while correcting the dislocation of the image between the time phases by a correction quantity corresponding to the calculated moving distance, the image data of a capture image 40 is formed. Thus, blurring of the capture image 40 is restrained by using the B mode image 30, and a locus of a blood vessel 42 becomes clear, and a structure of the fine blood vessel 42 can be observed.
