This study developed a CAD model of a female foot using computed tomography (CT) data from the National Institutes of Health's Visible Human Project. The CT data was segmented and edited using Materialise Mimics and Geomagic Wrap. The refined models offer detailed NURBS-based geometries suitable for finite element analysis. Pressure distribution data, crucial for realistic biomechanical simulations, was obtained using a Tekscan pressure mat, allowing for the integration of applied loads into the models to simulate actual foot mechanics. The integration of anatomically precise CAD models with functional load data provides a simulation process that can lead to improved solutions for foot-related ailments. This methodology paves the way for future research to leverage these models in predicting biomechanical responses under various loading conditions, enhancing our understanding of foot dynamics and aiding in the development of targeted interventions.
