[ITK-users] Fwd: problem with convert itk to vtk

[Роман Глуховский]

I change the part of my programm to load the ImageSeries,

    typedef itk::Image<unsigned char, 3> ImageType;
    typedef itk::ImageSeriesReader< ImageType >  ReaderType;
    ReaderType::Pointer reader = ReaderType::New();
    typedef itk::GDCMImageIO ImageIOType;
    ImageIOType::Pointer dicomIO = ImageIOType::New();
    reader->SetImageIO(dicomIO);

    typedef itk::GDCMSeriesFileNames NamesGeneratorType;
    NamesGeneratorType::Pointer nameGenerator = NamesGeneratorType::New();
    nameGenerator->SetDirectory("Folder");


    // get series IDs
    typedef std::vector<std::string> SeriesIdContainer;
    const SeriesIdContainer &seriesUID = nameGenerator->GetSeriesUIDs();

    // get dicom series
    typedef std::vector<std::string> FileNamesContainer;
    FileNamesContainer fileName;
    fileName=nameGenerator->GetFileNames(seriesUID.begin()->c_str());
    reader->SetFileNames(fileName);

    // pull reader
    reader->Update();

But my programm crash again at the same position, when i try to convert to vtk.
