FETAL BRAIN RECONSTRUCT

Post by Nomad »

Hi,
I wonder whether BV can reconstruct fetal brain.The process steps go well until "Brain Mask Segmentation".The result seems to be unbelievable.
Thanks a lot.

You mean antenatal imaging? We are working on that for years, but it is not ready to
distributed. You will get in a lot of trouble with a standard acquisition because of slice thickness.

It is somewhat hard to get a stable WM/GM contrast in the in-utero studies as the brain doesn't start to myelinate until parturition. The magnetization transfer imaging is the only stable way of getting good regional contrast in the unmyelinated brain that I know of. I had good luck with getting MTC images from in-utero primates to be processed with the bvisa tools.

Peter,
like often, you raised my curiosity, not only because of this MT sequence,
but also managing to do something with our stuff with this data, while it
is not the standard input. You did at least some kind of magic?

Well, I trully wish I was gifted with any supernatural abilities. Unfortunantly, it is the brute force permutation approach that gets the job done :cry:

Maybe what looks like supernatural abilities is a capacity to apply brute force strategy with a wet brain:-)
