[Insight-users] Changing a DICOM Header... in a DICOM Series

[Stéphane CALANDE]

I've tested "DicomImageReadChangeHeaderWrite" with the code :

  std::string entryId("008|103e");
  std::string value("NEW VALUE");

and it works...


I think the origin of the problem could be the dictionary :

In the code :

ImageType::Pointer inputImage = reader->GetOutput();
DictionaryType & dictionary = inputImage->GetMetaDataDictionary();
[...]
itk::EncapsulateMetaData<std::string>( dictionary, entryId, value );


I don't really now what represents the variable "dictionary". Because the
"reader" is a reader of a SERIE and of an IMAGE...

Then what returns GetMetaDataDictionary() of a DICOM serie ?

Do I have to find a way to iterate on the dictionaries of each image of the
serie ?
(Because I want to modify the header of each DICOM image...)



Thank you,


Stéphane
