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

[Bradley Lowekamp]

Hello Jason,

You are correct that you need a method like ImageSeriesReader::GetGDCMSeriesFilenames()[1] which is a static member function in C++.

I am not certain, but I believe SWIG translate these static member methods to global functions with names such as ImageSeriesReader_GetGDCMSeriesFilenames. But hopefully you can search for that function name and find it in the assembly.

Please let up know if you figure it out,
Brad

However this does not seem to appear in the assembly metadata (below).  Is there something I'm missing or a different route to achieve the same end result of loading the image in C#?  I'm assuming that others have loaded CT volumes in the C# wrapper before so I'm guessing it's something I'm doing incorrectly.  Thank you for any help!
