[Insight-users] itk::DiffusionTensor3D fa map

[Garin, Alba]

Dear all,

I am computing different DTI maps from an Image with itk::DiffusionTensor3D pixel type. If I get MD, Trace, First Eigenvalue and other maps, I get a correct map, but If I compute the FA map, I get high values (0.6) in the air part of the image (around the brain). I mean, even the brain can be distinguished from the air, there are values in the air. Is this normal? Have this happened to anyone before?

Thanks in advance.
Regards,
Alba
