PROBLEM TO BE SOLVED: To provide an art visually catching the movements of tissues over a plurality of time phases. SOLUTION: Segments are dynamically set across a plurality of frames according to the movement of the cardiac muscle using a method of pattern matching. Each segment of a segment group 8 is a segment that is set along the thickness direction of the cardiac muscle 1 and connects a specific portion in the tunica intima to a specific portion in the tunica externa, and the movement of the segment expresses the motion of the cardiac muscle. A graph 16 of length changes indicates changes in the lengths of the segments dynamically set across a plurality of frames and comprises a vertical axis indicating the lengths of the segments of the respective frames to the segment of a criterion frame and a time axis (a lateral axis) indicating the time phases of the respective frames. A graph 18 of angle changes indicates the changes in angles of the segments dynamically set across the plurality of frames, and comprises a vertical axis indicating the angles of the segments of the respective frames to the segment of the criterion frame and a time axis (a lateral axis) indicating the time phases of the respective frames.
