FIG. 6.

Results of both geometry and fiber orientation deformation of one slice from the canine heart data, including their estimation errors. Upper row is the geometric results and the lower row is the fiber orientation results. [(a1) and (a2)] Geometry and inclination angles of the target heart. [(b1) and (b2)] Geometry and inclination angles of the template heart. [(c1) and (c2)] Estimated geometry and inclination angles of the target heart. [(d1) and (d2)] Corresponding errors between the target and its estimation.
