Dear Saito,
id be very interested in the answer to your query.
I asked the same question on the list too somewhere in 2008 if i
remember well (search the archives for entries). At that point, it
seemed that fieldmap algorithms only handle axial slices (in-plane phase
encoding AP or PA, eg perpendicular to the main B-field).
I have hi-res 3T coronal 2DEPI images to undistort as well, but at that
point it seemed that redoing the physics (in general principle is
similar) and rewriting the math for phase encoding parallel to main
B-field was my only option. As undistortion is not my field, no surprise
I did not get to that yet, doubt i ever will.
Keep me posted....
cheers,
Bas
