DTI data motion correction

Dear SCT team
I would like to ask that my DTI data only has 15 gradient images and 1 b0 image and could I do motion correction before processing the DTI data? it is possible to calculate the averaged b0 as Xu did (Xu, et al. 2013)?

Thank you!

Sincerely,
Chang

Hi Chang,

Yes, you could do motion correction on your data. However, computing an ‘averaged’ b=0 image does not make sense in your case since you only have one image to perform the average (ie: the average of one image is the image itself).

Best,
Julien

Hi @chang,

SCT has a tutorial for DTI motion correction that you can find here: Diffusion-weighted MRI - Spinal Cord Toolbox documentation

In particular, you will want to use the commands listed on the following pages:

Kind regards,
Joshua
