[Insight-users] Loading a CT Volume in C# - SimpleITK or ITK

[Jason Gibbs]

Brad,

Thank you for the response!  I'm pretty sure that global functions aren't
allowed in C# so it would have to be shoved into some class somewhere, with
the natural one being ImageSeriesReader.

I did search through the assembly for any "GDCM" substring in the object
browser; no luck.  For now I've wrapped the function on my own and it works
fine.  However I'd be interested if anyone has a more elegant solution
moving forward.

Thanks again!
Jason
