Three-Dimensional Modeling and Finite Element Analysis of the Human Diaphragm

The diaphragm is a crucial muscle in respiration, creating the pressure gradients necessary for inhalation. This thesis focuses on a computational methodology to reconstruct the diaphragm’s geometry using CT imaging and simulate its biomechanical behavior under physiological loading via Finite Element Analysis (FEA). ITK-SNAP was used for medical image segmentation, CATIA V5 for 3D reconstruction, and ANSYS for simulation under various pressure scenarios. The reconstructed diaphragm model was validated against anatomical landmarks and literature-based deformation ranges, showing good agreement. The proposed workflow provides a robust approach for modeling soft tissue biomechanics.
