Hi,
By means of the option -A BET produces the inner skull mask. I have
a few questions about this mask
1.
As it name suggests the volume of the inner skull mask is an estimate of the ICV.
Is that correct?
2.
It frequently happens that the inner skull mask is smaller than the brain mask, i.e.,
voxels inside the brain mask are located outside the inner skull mask. Of course,
this is anatomically not correct and therefore I would like to ask you to modify BET
in this respect.
May I conclude that the algorithm to derive the brain mask is different from the
algorithm which derives the inner skull mask?
3.
Related to question 2: we are frequently editing manually the brain mask. It’s a
pitty that this modified brain mask can not be used as input to BET to improve
the computation of the inner skull mask. Is it possible to add such an option to BET?
Cheers,
Ed
