medical physics department. We are developing a new non-invasive neuro-imaging
technique based on electrical impedance (EIT).<br>
For our finite element modelling and reconstruction purposes we use volume
meshes which we segment manually out of anatomical images. However, our
procedure is inefficient and inaccurate.<o:p></o:p></span></font></p>

cubes, I suspect) for brain, inner skull, outer skull and CSF. The files
are in dfs format, and it’s possible to save the vertices in ascii format
