The technique includes using two or more motion-sensitive sensors, disposed on a patient in a region of interest proximate to the internal organ, which acquire motion data along the surface of the patient. The motion data may then be processed and displayed to depict or characterize the mechanical motion undergone by the internal organ. The mechanical motion may be displayed as an image or video. In addition, the mechanical motion data may be combined with other measured data, such as electrical or acoustic data, or with images acquired by other imaging modalities to generate a composite image.
