First, I looked at the ventricular structures in the center of the brain. I do this by deleting the outer surface of the cortex in my previously generated 3D model. (Note that I may have to tweak the isosurface generation parameters from MRI data, in order to better segment internal structures.) The ventricular structure is roughly highlighted in green:
I think you can even find the foramina of Monro, which connects the lateral ventricles to the third ventricle:
Other things I am interested in are:
- Do I have an intact Circle of Willis? (This will probably require resegmentation of the MRI model.)
- Can I obtain a nice model of the half hemisphere?
