Hello,
I want to extract the inskull, outskull and scalp surfaces with betsurf. The results I have obtained for inskull and scalp are good. But my success on outskull surface determination changes a lot for different data sets. Sometimes the results are really good but for some data they are clearly wrong although the outskull is clearly visible in T1 images. The script I used for that purpose is given below with parameter values changing for different subjects. The problem is probably the bright spongiosa in T2 images (but we want to have those too because we want to get as much information as we can about the skull). I also tried to obtain the outskull from just T1 images but it was no good either. Are there anything you could recommend ?
fsl4.1-bet Input_T1 output_brain.nii -m -f 0.35 -c 99 100 169 -A2 Input_T2
Thanks a lot,
Cheers,
Ümit
