There is a user library routine which I think will do what you want:
; NAME:
; EXTRACT_SLICE
;
; PURPOSE:
; This function returns a 2-D planar slice extracted from
; 3-D volumetric data. The slicing plane may be oriented at
; any angle, and may pass through any desired location in the
; volume.

One you have the 2D array, IDL can FFT it eaisly, I'm also sure you could
perform most analysis and generate graphics without too much trouble.

Can IDL take a cut in the off-plane directions?
yes. it's the irregularly gridded data problem and they have several
levels of transformation available.
at FIT, you ought to talk to Bruce Rafert, who should have a copy....
