摘要
the present invention is a computer tomography (CT) in a two-dimensional medical images generated by the three-dimensional shape model from will reconfigure (Surface Model) and a method for reconstructing a three-dimensional shape model by the 3D finite element model that can perform computer simulations of (Surface Model) (3D Finite Element Model). The shape model (Surface Model) is connected to the three-dimensional shape of the surface triangles are triangles to represent a configuration consisting of lung surfaces and three-dimensional finite element model (3D Finite Element Model) model, the internal volume is filled with a triangular form of tetra-head consists of theory element (Tetrahedron Element). ; The invention and separate the background and the target object with respect to each of the two-dimensional medical image section to configure a three-dimensional shape, outside of the target object stacking the two-dimensional outline of the first stage and the outer region of the background, each separated in the first step of performing image zoning (Segmentation) operation that the extraction area, inside the empty three connect to the laminated outlines dimensional shape model consisting of a closed-form surface (Surface Model) the second step and the third step and the third step of the user adjusting the model accuracy of three-dimensional shape model (Surface Model) generated in the second step of forming a Accuracy adjustment at the user's operation is completed, the volume filled with the three-dimensional shape model (Surface Model) and Rhone-tetrafluoro head element of triangular shape (Tetrahedron Element) comprises a finite element model in the fourth step of generating the final.
