A Novel Method of Creating Models for Finite Element Analysis Based on CT Scanning Images
A novel method of creating models for finite element analysis (FEA) from medical images was proposed in this paper. The CT scanning images of human right hand were imported into a medical image processing software Mimics and the 3D STL model of the bone framework was reconstructed by selecting proper threshold value. A piece of the radius was cut from the bone framework model and remeshed in Magics to obtain triangles with higher quality and optimized quantity. The remeshed radius model was exported into FEA software ANSYS to create the volume mesh, and the unidirectional loading simulation was analyzed. This method eliminates the need for extensive and long time experiments and provides a helpful tool for biomedicine and tissue engineering.
