An ultrasonic imaging apparatus and an ultrasonic diagnosis apparatus including the ultrasonic imaging apparatus comprise an image acquiring unit, extracting unit, tracking unit and physical parameter calculating unit. The image acquiring unit acquires image data of a subject, the extracting unit extracts a plurality of trackable characterizing points based on the acquired image data, the tracking unit tracks the movement of the characterizing points, and the physical parameter calculating unit acquires specific physical parameters, such as displacement, distortion and distortion velocity, based on the information derived from tracked results, of the characterizing points contained in each region of interest (ROI). Both of the ultrasonic imaging apparatus and an ultrasonic diagnosis apparatus make it possible to easily and accurately perform extraction of characterizing points and low-cost analysis of contraction/expansion functions of the heart or the like.
