Hello, I'm using Fiberfox to generate very simple fiber geometries and I
keep getting Nifti files with very low range of intensities between fiber
and non fiber voxels. I want to know if I'm doing anything wrong or if this
behavior is expected.
I have been playing around with the model values, but I can't get a big
range of intensity values. For example, the difference between fiber and
non fiber voxels is only one unit of intensity values (71 and 70).
Maybe I'm configuring badly the parameters in the model configuration
between intra-axonal, extra-axonal and extra-axonal compartments.
*Intra-axonal values are:*
T2-relaxation: 110 ; FA: 0.97
*Inter-axonal values: *
T2-relaxation: 110 ; FA: 0.97
*Extra-axonal values (Ball-model): *
T2-relaxation: 80
If needed I can provide more information.
Thanks,
--
