[Insight-users] read dicom images, register and write out dicoms with no change in metadata

[Tadimalla, Sirisha]

Hi, 

I am trying to register two dicom MR images as part of a project. I need the dicom header information to be unchanged in the registered dicom output. I also need the Private tags in the output header. When I build and run it, I get a registered image in DICOM format, and I have most of the original header information, but it doesn't contain the private tags. Here is part of the code that I have used:

#include "itkGDCMImageIO.h"
#include "itkImageFileReader.h"
#include "itkImageFileWriter.h"

ReaderType::Pointer movingReader = ReaderType::New();
ImageIOType::Pointer movingdicomIO = ImageIOType::New();

movingReader->SetFileName( argv[2] );

movingReader->SetImageIO( movingdicomIO );
movingdicomIO->SetMaxSizeLoadEntry(0xffff);
movingdicomIO->LoadPrivateTagsOn();
movingdicomIO->KeepOriginalUIDOn();

/// Registration is done here and then the output dicom has to be written

writer->SetInput( caster->GetOutput() );
writer->SetImageIO( movingdicomIO );
writer->SetFileName( argv[3] );
writer->UseInputMetaDataDictionaryOff();

writer->Update();

Please help.
Thank you
