The data management of 3D FE model reconstruction based on medical Images and the modeling for T10-T12 thoracic vertebrae / 生物医学工程学杂志

ABSTRACT

Setting up the 3D finite element (FE) model on the basis of medical images is a necessary method of biomechanical analysis. The pretreatment, including data processing of images and mesh generation, becomes the bottleneck of FE analysis, and this is especially the case of the modeling for thoracic vertebrae, because the shapes and data are complicated. In this paper, on the basis of the data for building a 3D FE model of thoracic vertebrae, we present some structures and types of data which are essential for the reconstruction of CT medical image, analyze some methods for obtaining and processing the data from images, and then advance a theory for data management based on mesh generation by block with the software MSC. Marc. A 3D-FE Model of T10-T12 thoracic vertebrae is set up, which keeps the configuration of the true one, and satisfies the requirements of biomechanical analysis. We focus affention on the data obtainment and management during medical image processing and FE modeling, all of which are very important for the biomechanical analysis. It is helpful and instructive to reconstruct some similar tissues of human body on the basis of the medical images from CT, MRI, etc.
