Maloney <[email protected]<mailto:[email protected]>> wrote: Hi all, Thanks for the help getting my reconstruction up and running last week I apologize if I missed something obvious I was hoping to use an iterative technique but I'm having trouble getting it running Is it required to set a forward projection filter? The relevant code is: using FDKGPUType = rtk::CudaIterativeFDKConeBeamReconstructionFilter; FDKGPUType::Pointer feldkamp = FDKGPUType::New(); feldkamp->SetInput(0, constantImageSource2->GetOutput()); //Reconstruction Volume feldkamp->SetInput(1, reader->GetOutput()); //Projection Images feldkamp->SetGeometry(geometry); I get an error here: Exception thrown: read access violation. this->m_ForwardProjectionFilter.m_Pointer was nullptr. On line 121 of rtkIterativeFDKConeBeamReconstructionFilter.hxx This looks like it doesn't set a forward projection filter by default. I'm struggling a bit to get the format for setting this correct Thanks for the help!
