Mesh generation of a lumbar vertebra, illustrating the segmentation and meshing process. (a) Extracted vertebral geometry from CT segmentation. (b) Processed vertebra with a defined inner boundary for cortical and cancellous separation. (c) Surface mesh representation of the vertebra. (d) Cross-sectional view highlighting the distinction between cancellous and cortical bone. € Integrated finite element mesh with applied boundary conditions, demonstrating the preparation for FEA simulations.
