[Insight-users] Reading and Writing Dicom Series

Hello all,
I performed segmentation slice by slice, and saved them also slice by slice. Then while reading this series and writing them into one single '.mha' file, it only writes the first slice. I am using "DicomeSeriesReadImageWrite2.cxx" of the user-guide. Actually it works quite well with my other dicom data series. But with this one no. I can see my segmented data slice by slice in Matlab, which indicates they are written correctly. So I cannot figure out where the wrong part is.
Here are the data types for segmenting and saving slice by slice that I've used:
******************************
typedef float InternalPixelType;
const unsigned int Dimension = 3;
typedef itk::Image< InternalPixelType, Dimension > InternalImageType;
typedef unsigned char OutputPixelType;
typedef itk::Image< OutputPixelType, 3 > OutputImageType;
typedef itk::ImageFileReader< InternalImageType > ReaderType;
typedef itk::ImageFileWriter< OutputImageType > WriterType;
*****************
And, here are the data types for reading the saved slices and writing them into one single file (which is in the DicomSeriesReadImageWrite2.cxx in the user guide):
***************
typedef signed short PixelType;
const unsigned int Dimension = 3;
typedef itk::OrientedImage< PixelType, Dimension > 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->SetUseSeriesDetails( true );
nameGenerator->AddSeriesRestriction("0008|0021" );
nameGenerator->SetDirectory( argv[1] );
std::string seriesIdentifier;
if( argc > 3 ) // If no optional series identifier
{
seriesIdentifier = argv[3];
}
else
{
seriesIdentifier = seriesUID.begin()->c_str();
}
typedef std::vector< std::string > FileNamesContainer;
FileNamesContainer fileNames;
fileNames = nameGenerator->GetFileNames( seriesIdentifier );
reader->SetFileNames( fileNames );
try
{
reader->Update();
}
catch (itk::ExceptionObject &ex)
{
std::cout << ex << std::endl;
return EXIT_FAILURE;
}
typedef itk::ImageFileWriter< ImageType > WriterType;
WriterType::Pointer writer = WriterType::New();
writer->SetFileName( argv[2] );
writer->SetInput( reader->GetOutput() );
****************
Thanks in advance.
