Hello
Where can I get information on how freesurfer calculates volumes of subcortical structures ? Is there a paper which provides insights into this method ? Is it that for certain subcortical structures, it just counts the number of voxels and adds them up since the voxels are 1mm3 ?
Thanks
Subha
Hi Subha
no, it starts with that then we estimate the partial volume fractions of every border voxel by compute the mixture distributions of that label and the most likely neighboring label. Not sure if this has been written anywhere - maybe in Xiao Han's reliability paper?
