I would suggest the following steps. Some of these are from the 3D Slicer package. First, there is a module in Slicer called SkullStripper. This should be a pretty good estimate of the brain. Next you can either use the EM segmentation module in Slicer or you could write your own tissue classification program. For example the K-means segmentation is ITK works pretty well for a quick segmentation assuming that you do not have large bias fields. Next, there are two meshing modules in Slicer (Voxel Mesh and IA_FEMesh). Both or capable of generating a hex mesh. You would need to write a translator to get the result into a format suitable for Ansys.<BR>

Thanks for your fast reply,<BR>
<BR>
I have a MRI brain volume, i wanna to do that:<BR>
1- Extract the Brain only from the volume. <BR>
2- Segment Brain to Gray / White matter/ CFS. (may be tumor in the future will be considered)<BR>
3- Output this segmented volume to FEM (Ansys) . <BR>
Regards,<BR>

Hi Yasser,<BR>
<BR>
Do you need something more detailed than Skull-removal ?<BR>
<BR>
The first thing in MRI will be to evaluate whether<BR>
you need bias-field correction or not.<BR>
<BR>
Please provide more details on what you are trying to achieve.<BR>
<BR>
<BR>
Thanks<BR>
<BR>
