Over 18 months ago, we kicked off the ExTASY project. Our lofty aim was to tackle one of the 'Grand Challenges' of biochemistry - effective sampling of complex biomolecules using Molecular Dynamics to provide a physical understanding of their function and behaviour.

Them bones, them bones: finite element bone-modelling

I have been re-architecting the solver-side of VOX-FE, a voxel-based finite element bone modelling suite developed by Prof. Michael Fagan's Medical & Biological Engineering group at the University of Hull. The suite comprises a GUI (you can read more about it in this blog post) and a linear solver. VOX-FE creates bone models made up of small cuboid elements by directly converting Computed Tomographic data into these elements. This circumvents the problems faced by the more common method of model creation via mesh interpolation (loss of detail, scaling issues). VOX-FE's approach makes modelling an entire skull with surrounding soft tissue a realisable goal. However, it’s not quite there yet.
