If you know a point on whatever you consider to be the first slice of
the volume, then all you need to do is compute the distance of the
slice plane from that point.  But what do you consider to be the
"first slice" when you are doing an oblique reformat?  Really, it's
arbitrary.  The numbering of the slices is up to whoever is developing
the application.
