Factors affecting subject-specific finite element models of implant-fitted rat bone specimens: critical analysis of a technical protocol

John Botsis, Joël Cugnoni, Marco Piccinini

The authors propose a protocol to derive finite element (FE) models from micro computer tomography scans of implanted rat bone. A semi-automatic procedure allows segmenting the images using specimen-specific bone mineral density (BMD) thresholds. An open-s ...
