Hello everyone,
I'd like to revive this old topic, as I am currently stuck in a similar problem.
I would like to perform distortion correction in a slice-wise manner (I am assuming there is no/little motion between blip up and down). Is there any trick for that?
I am fitting a model on a set of volumes to extract some relevant parameters. When I look at the map of the cost function at the end of fitting (sum of squared residuals), it has a weird "zebra" like appearance, meaning that in some slices the fitting is not working as well as other slices. This is not the case when I fit the data without performing distortion correction as first step.
Thanks for your help.
Marco
