1. A medical image diagnosis apparatus comprising: a morphological-image forming part configured to detect data in which a morphology of the inside of an object is incorporated and form a morphological image showing a morphology of a range including an organ of the object based on the detected data; a part configured to receive an analysis image formed by another medical image diagnosis apparatus and representing a state of the organ; a wall motion analyzer configured to analyze the analysis image to determine a state of wall motion of the organ; a functional image generator configured to generate a functional image reflecting the state of wall motion determined by the wall motion analyzer; a display; and a processor configured to cause the display to display a synthetic image based on the morphological image and the functional image.
