Image Processing & Mesh Generation
A model of the equine MCPJ was generated by importing CT scans of the in vivo joint into Simpleware ScanIP. Image data was then processed using semi-automated tools to obtain Regions of Interest (ROI’s). The proximal sesamoid bone complex (composed of the medial and lateral proximal sesamoid bones (PSB)), as well as the intersesamoid ligament and the third metacarpal (MC3 bone) were individually segmented. Landmark points were also created for the model using intuitive measurement tools. Surface meshes and volume meshes were then automatically generated from segmented image data using Simpleware +FE for export to OpenSim and Abaqus/Explicit.
