Thanks Matthew. If this were to make it's way to scipy, I think it would be
good for it to read stacked tiff's. That's the format that's used by
molecular biologists and neuroscientists to store confocal microscopy and
other imaging data.

A 2D image is a volume with the 3rd dimension set to 1. So if I extracted
slices from a volume would I have to do:

someotherpackage.save(my2Dslice,'canIbea3dvol.dcm')

instead of

medvol.save(my2Dslice,'iama3dvol.dcm')

I think my general point is that if this was purely a neuroimaging thing, it
should remain within NiPy. However, if it is more generally applicable to
medical images, then it should seriously consider a framework in which it
can support other common volume-like formats.

Cheers,
