I create my own library to read RT structure. There's a also article in Insight Journal that discusses about import RT Structure using Insight. You should be able to find it with a simple google search.<BR><BR>Xiaofeng<BR><BR><BR> <BR>> Date: Tue, 4 May 2010 17:54:36 +0100<BR>> Subject: Re: [vtkusers] Fwd: Re: RE: Create an approximate cross-section of a RT ROI<BR>> From: jothybasu@gmail.com<BR>> To: xf10036@hotmail.com<BR>> CC: lars-friedrich@gmx.net; vtkusers@vtk.org<BR>> <BR>> I cut with vtkCutter,but the first step is to read RT structure data<BR>> as vtkPolyData.
