Abstract—The purpose of this study is to develop Computer-Aided Design (CAD) tools to construct three dimensional (3D) bio-printing models of human coronary artery from medical images. Two methods are used to construct mimic models from Computed Tomography (CT) scans. A simple model is also constructed by simplifying the mimic model. Two local view method uses two orthogonal image to construct the model, while transverse image lofting method lofts a series of transverse image to construct the model. Both methods are effective. However, more mimic result can be acquired from transverse image lofting method.
