If you want to view, anonymize, convert, I have found GUI and CLI tools 
on Linux
to be more than adequate (as a dev). In particular, check out Aeskalup 
and GDCM,
both in Ubuntu (and, I expect, Debian) package repositories. For 
something more
in depth, perhaps MITK Workbench (mitk.org) or ITK-SNAP (itksnap.org). 
As you
mentioned, ITK itself has most of the core functionality, in library 
form, and has
Python bindings for scripting (as well as native C++).

For something a bit different: Paraview can actually volume render NifTI 
which Aeskulap can chuck out from DICOM, by turning on a default-disabled
plugin. Check out AnalyzeNifTI in the (not very intuitive) Plugin menu. 
may be useful if you want to open segmented surfaces or overlaytext/3D CAD
geometry, or other. If you want to use Paraview for some basic 
I have found applying PointDataToCellData and CellDataToPointData 
filters on
top of each other gives enough blurring of noise to make taking an 
IsoVolume sort-of-work, but nothing that's going to revolutionize proper

With best wishes,
