An ultrasonic diagnosis device having a data collector that collects ultrasonic image data, obtained by scanning a predetermined site of a sample periodically moving, a strain gauge setting unit that sets a predetermined number of strain gauges which includes a plurality of segments connecting two end points one or more middle points existing between the end points in the interesting area, a motion vector information generator that generates motion vector information of the tissue including at least the strain gauges, an image generator that sets a predetermined number of strain gauges in the ultrasonic image data at different time phases during the period and generates a strain gauge image in which the strain gauges are overlapped at a corresponding position, by the use of a tracking process using the set strain gauges and the motion vector information of the tissue, and a display that displays the strain gauge image.
