Hello everyone,
At the moment I'm working on tractography with DTI images. I'm trying
to make an study on images which has been done in different machines,
(I know this is highly discouraged) and some of those images has
different sequences from 16 to 64 gradient directions. It's not the
ideal scenario.
My doubt is if there is anyway of reducing the 64 directions images to
16 in order to make them comparable. I have thought of simply erasing
gradients until I have 16, but that could lead to some unbalance. Also
averaging some images etc...
Is there a known method for acomplishing this? Does averaging DTI
images and gradients makes any sense?
Cheers and thanks for your help,
Luis.
