Comparing with 2D medical image,3D medical model has many advantages at anatomy study,surgery assistant and manufacturing supporting.Because of the difficult on reconstruction of 3D medical CAD model,the 3D model is not widely used in practice although theory study has been done more.Aiming at this problem,a reconstruction strategy based on medical image processing,reverse engineering and forward design is proposed.Application indicates that 3D medical model can be reconstructed facilely and effectively bas...
