[Insight-users] DICOM Registration

Wed May 2 07:19:20 EDT 2012

Dear Jeff,
I would dare to say that the DICOM dictionary information provided is not
that important concerning your program not working. I think you shouldn't
be troubled by the information contained in the dictionary.

The fact that the datasets are in different locations is not an issue to
ITK neither. Once you load them into memory, ITK does not need any further
information on their location.

It looks like the reader successfully reads both series; the problem is
elsewhere.

Please try to go step by step and see where the problem lies in reality.

You may try to reproduce the result of the examples as it is to start with.
