Dear FSLer
I have 52 directional DTI data which were acquired with coronal direction
(posterior to anterior) and also 52 vector values of images coronally acquired.
If I have DTI data which were acquired with axial direction, FSLview shows
axially sectioned image at left inferior quater of fslview window.
But FSLview shows coronally sectioned image at left inferior quater of
fslview window because my DTI images were acquired with coronal direction.
My question is when I have to convert 4d DTI data coronally acquired to the
same orientation with avg152T1 (LAS system).
One possible method would be that I reorient 4d DTI images BEFORE putting
them into DTIfit. In case, do I have to change 52 vector values of images
coronally acquired and is it possible?
Another method would be that I reorient the products (FA images, L1..,
ADC...) of 4d DTI images AFTER putting them into DTIfit. In case, can I use
52 vector values of images coronally to get FA, ADC, L1... from 4d DTI image
acquired coronally. Also I should have to B0 and brain mask with direction
before reorienting.
Thanks in advance
