An ultrasonic diagnostic apparatus according to an embodiment includes a processing circuitry. With respect to pieces of image data of a plurality of cross sections passing through the heart of a subject that have been collected by ultrasonically scanning each of the cross sections for a period of at least one heart beat, the processing circuitry performs tracking processing including two-dimensional pattern matching to generate pieces of analysis information in each of which a cardiac wall motion of the heart in each section is analyzed. The processing circuitry matches time phases of the pieces of analysis information of the cross sections and maps the pieces of analysis information of the cross sections with the matched time phases on a predetermined polar coordinate system to generate a polar coordinate display image. The processing circuitry causes display of the polar coordinate display image.
