N3 (authomatic correction of intensity in MRI data) [message #89705]

Hello, I'm trying to implement this algorithm in IDL.
(papers: https://www.nitrc.org/docman/view.php/6/880/sled.pdf ; https://www.dropbox.com/s/4mmys4ikb92ya4l/original%20-%20SLE D%20John%20G.%20Sled.pdf)
After a few weeks of researching I still have troubles understanding the b-spline smoothing.
From what I understand it uses a TRICUBIC b-spline approximation, but I cannot find any function already implemented in IDL that can do more than a 2d spline approximation. Can anybody point me in the right direction?
Any tips would be useful, thanks in advance.
