Brief Description: |
A range Finite Element meshes of different densities for the human
head including two neonate meshes.
The underlying geometry is described in Tizzard et al. (2005b) and all meshes except SA262 are used in Tizzard & Bayford (2007a) | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||

compressed with 7-Zip
Each model is shelled comprising regions defining Scalp, Skull, CSF and brain as defined by the materials structure. The important arrays in this structure are names and ref. The vector ref relates elements (tri) to each region by index into the names array. Nodal positions (mm) are defined by the vtx array. The underlying geometry is described in Tizzard et al. (2005b) and all meshes except SA262 are used in Tizzard and Bayford (2007a) | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Methods: |
Geometry generated using Alias Studio Tools (now Autodesk Alias)
and the meshing carried out using EDS I-DEAS (now UGS NX).
The tables below give a summary of the adult and neonate head meshes. They are all shelled comprising regions defining Scalp, Skull, CSF and brain. The underlying geometry is described in Tizzard et al. (2005b) and all meshes except SA262 are used in Tizzard and Bayford (2007a) Some of these meshes and others based on the same underlying geometry have been used by the UCL and Middlesex groups (Bagshaw et al. 2003; Bayford et al. 2005; Bayford et al. 2006b; Bayford et al. 2006a; Horesh et al. 2004; Tizzard et al. 2005a; Tizzard and Bayford 2007b; Yerworth et al. 2004).
