I have a stack of 2D dicom images and want to convert to a 3D object using VB.NET. I suppose I can solve it using openGL but any clue would help a lot. Do you know a free (or at least cheap) pack to do it? Would you help me to think my own solution. Thanks...

A: 

I would suggest using the Visualization Toolkit to do this. Although I haven't used it before, there is a .NET wrapper for VTK here.

If you want precompiled versions of these libraries, ClearCanvas has them checked into their repository. This page has instructions on accessing the ClearCanvas SVN repository. The SVN folder where the files are contained is here: svn://svn.clearcanvas.ca/source/Xian/Trunk/ReferencedAssemblies/Vtk

Thank you very much for this answer. Just one doubt: I need to convert the sequence of dcm files into a VTI file and, finally, show this file using the VTK control. Am I right?

The use of the VTK control as mentioned on the VTK for .NET page is not required, but this is probably the fastest way to get data displayed. I would recommend starting this way. I don't have any experience myself using VTK, but I know its widely used in the industry for 3D.

Steve. Thanks a lot!!! The VTK control is great and it seems it was suited for me ;-)
