Hi John

I doubt it will work. We incororporate a *ton* of information about human neuroanatomy that will not be present in your phantom.

Hi,

I have MRI scans of a plastic polycarbonate ventricle that is an actual shape of a ventricle. It is in a brain mold of agar gel solution. I segmented the ventricle successfully using multiple seeds fuzzy connectedness in ITK. My segmentation was 97.2 % accurate. In ITK it had only single seed fuzzy connectedness but I adapted the code to work with multiple seeds. The reviewers of our paper want us to use FreeSurfer to segment the ventricles. Can I use freesurfer when the brain mold only has ventricles and grey matter (agar gel)? Or does Freesurfer require the brain to have the same number of brain parts as the Talairach atlas that it uses? My hunch us that it is the latter case.

Thank you for your time. John
