SCANCO Finite Element Software The Scanco Finite Element software consists of several additional software modules to enable Finite Element (FE) analyses. With this type of analyses it is possible to simulate mechanical tests in order to calculate bone mechanical properties and loading conditions. • A solver for linear elastic microstructural finite element • A solver for non-linear continuum finite element analyses using fabric/density based properties1 • An export tool to convert micro-CT images to input files for 3rd party FE-solvers • Tools for pre- and post processing Example 1 Finite element analysis of bone in-vivo measured with the XtremeCT. A compression test is performed on the measured section of the radius. Finite element solvers • Integrated in the standard evaluation-tasks workflow: FE-analysis can be started with a few mouse clicks • Integrated in Scanco-IPL for scriptable user-defined • Contains a built-in library of pre-defined tests (compression, tension, torsion, bending etc.) • Micro-FE models can represent the actual bone microstructure for linear elastic analysis • Continuum-FE models can represent the homogenized bone microstructure for elastic/plastic/damage analysis1 • Results of FE-analyses are stored in a database for easy • Mechanical analysis of XtremeCT images • Well validated and standardized approach to measure in-vivo mechanical properties of bone • Measured mechanical properties include: - Failure load - Load distribution (cortical/trabecular) • Enables measurement of changes in mechanical properties over time • Mechanical analysis of vivaCT and microCT images • Simulation of any mechanical test • Complete characterization of elastic properties of bone samples • Determination of bone tissue-level loading Example 2: Von Mises stress distribution in a mid- section of the vertebrae (blue=low, red=high). best ortbotropic coordinate systen Example 3: Calculation of average elastic properties of a cube of trabecular bone For further information regarding the equipment and software as well as contract imaging research options contact SCANCO Medical AG or visit our website at: http://www.scanco.ch http://www.microct.com
