Motion is automatically characterized from ultrasound information. Ultrasound information associated with particular time periods relative to a cycle, such as the cardiac cycle, are extracted, such as identifying and extracting ultrasound information associated with systole. By tracking an area of the heart, such as an area within the endocardial contour, the heart cycle time periods are identified. Spatial parameter values are determined as a function of time from the extracted ultrasound information. For example, the timing of motion, the eigen motion, the curvature, the local ejection-fraction ratio and/or the bending energy of parts of the cardiac tissue are determined. The spatial parameter values characterize the motion.
