After trying the three available wrappers (CSwig, WrapITK shipped with 
ITK, and WrapITK from Google Code), I would definitely go with WrapITK, 
preferably the Google Code version : they are much closer to Python than 
the CSwig wrappers, and exploits more features of Python (have a look at 
the Google Code page for some examples).

They have become fast : WrapITK is definitely an improvement over CSwig, 
and the latest version of WrapITK takes this one step further. As to 
memory usage, I haven't done any kind of benchmark.

I haven't tried this, but you might take a look at the DICOM examples 
from the ITK software guide (section 7.12.5) : create a DICOM image IO, 
get the metadata, and, based on those metadata, create your reader with 
the correct image type.
