Sounds like you want to convert it to NIfTI format. We have a number of
packages in Debian that can do that (dicomnifti, mriconvert, dcm2nii,
...).
Once it is in that format you can view, surf it with many tools also in
Debian (fslview, mricron, itksnap, amide, ...). We also have tools to
turn your brain into 3d meshes (slicer, caret) for true 3D rendering.
A bit of background: NIfTI is the defacto standard for data exchange in
neuroimaging research (less information than in DICOM, pretty much only
what is relevant to the data, no personal information or infromation
on acquistion equipment). NIfTI also supports compressed storage
(basically gzipping the file, without the need to uncompress it before
loading into an application) -- that should shrink the size on disk
quite a bit.
In case the software in Debian proper is not enough (although it
should): Here is more: http://neuro.debian.net/pkgs.html
