[Insight-developers] Has anyone written synthetic DICOM series

[Williams, Norman K]

I found a really bad bug in the DCMTK reader.  When I wrote it, I got rows
& columns mixed up in assigning image dimensions.  Until now no one had
ever run into it because either they never use DICOM files, or they only
use DICOM series with square slices.

I've spent a couple of hours trying to write a test for this, that would
write a DICOM series of non-square slices.  Turns out it's not that easy
-- the DCMTK reader depends on DICOM tags to be in the DICOM file in order
to read them in successfully, and the DICOM writer (GDCM) I have access to
doesn't fill them out properly.

I can simply use some anonymized real-world data to do this, but it's
disconcerting we can write files that aren't actually readable. Is there
some trick to this that I'm missing?

Looking at the GDCM tests, there are places they write GDCM files, but
they actually read a DICOM file first and copy the MetaDataDictionary onto
the output in order to get the flags in.
