[Rtk-users] ConjugateGradientConeBeamReconstructionFilter

[Ali ghorbanian]

Hi,
I read the projections of a fan Beam CT by below syntax:

using ReaderType = itk::ImageSeriesReader< OutputImageType >;
ReaderType::Pointer reader = ReaderType::New();
const unsigned int first = std::stoi("10000");
const unsigned int last = std::stoi("10403");
using NameGeneratorType = itk::NumericSeriesFileNames;
NameGeneratorType::Pointer nameGenerator = NameGeneratorType::New();
nameGenerator->SetSeriesFormat("F:/Data Aqu/98.04.17/Tiff-1/%04d.tiff");
nameGenerator->SetStartIndex(first);
nameGenerator->SetEndIndex(last);
nameGenerator->SetIncrementIndex(1);
reader->SetImageIO(itk::TIFFImageIO::New());
reader->SetFileNames(nameGenerator->GetFileNames());

How <https://fastdic.com/word/How> to <https://fastdic.com/word/to> set
<https://fastdic.com/word/set> uniformWeightsSource
<https://fastdic.com/word/Ali>'s parameter
<https://fastdic.com/word/parameter> in <https://fastdic.com/word/in>
ConjugateGradientConeBeamReconstructionFilter
<https://fastdic.com/word/Reza>?


typedef rtk::ConjugateGradientConeBeamReconstructionFilter< OutputImageType
> ConjugateGradientType;
ConjugateGradientType::Pointer conjugategradient =
ConjugateGradientType::New();
conjugategradient->SetInput(tomographySource->GetOutput());
conjugategradient->SetInput(1, reader->GetOutput());
conjugategradient->SetInput(2, *uniformWeightsSource*->GetOutput());
conjugategradient->SetGeometry(geometry);
conjugategradient->SetNumberOfIterations(1);
conjugategradient->SetDisableDisplacedDetectorFilter(true);
conjugategradient->SetGamma(1);

Best regards
