The current medical and engineering technologies help us in various fields of surgeries such as surgical simulations, preoperative plannings, intraoperative supports, and diagnostic explanations.In preoperative plannings, the simulation model of the target organ is necessary, and it is usually made from fine images that are obtained by some imaging devices such as CT (Computed Tomography) or MRI (Magnetic Resonance Imaging).However, these devices are too big to use during the surgery although there is a MRI device that can be used during the operation.On the other hand, the device of Ultrasonography (US Echo) is so handy that it can be easily used during the operation without radiation or magnetic effect; however, US images are not usually used for the construction of 3D model because they have so many noises and are not as clear as CT or MRI.Therefore, we have tried to construct 3D volumetric shape model from 2D US images by using image processing technique.Our concrete target organ and surgery are the aorta and Annuloaortic Ectasia (AAE), respectively.
