The development of modern skin flap chirurgery needs badly the three- dimension picture system to display the blood supply and other profound structures and functions. This kind of system can also support the clinical training, designing of operative route, suppositional operation procedure and fidelity navigation during the operation. 3D imaging studies such as computed tomography and magnetic resonance provide the primary source of patient-specific data for such medical applications. The two-dimensional (2D) images produced by CT and MR imaging techniques represent a series of cross-sectional image slices through ones anatomy.
