3 Method for constructing 3 dimensional finite element model of somatic structure

摘要

The present invention relates to a method of configuring a three-dimensional finite element model visualize the biological structure or necessary for the structural analysis from the image generated by a computer tomograph.; Removing the three-dimensional finite element model configuration method tomography two-dimensional image for each region that indicates the outline of the biological structure, and, outside the outline of a pixel in a predetermined interval according to the present invention; Each pixel in the external outline of the image are removed in a plane perpendicular to the direction the image forming for each pixel inside the outline to elevated by the same distance to form a graphic structure by generating a three-dimensional cuboid structure of voxels on each pixel; Determining a characteristic element of the voxels according to the intensity of the pixels corresponding to each voxel; Define a finite element for each voxel, and comprising the step of adding the element geometry and attribute information newly generated in the three-dimensional finite element model.; According to the present invention, do not require the CAD operation and net partitioning is less labor and time required it as the three-dimensional structure of a living FEM model configuration, it is easy to express the physical properties of the biological structure.
