[Insight-users] Dicom Image : How to access to all the tags

[edoardo.belletti at alice.it]

Hi Insight-users, 
I have a problem: I don't know how can I access to all the tags present in a dicom image.
With the code used in the example of the manual (Examples/IO/DicomImageReadPrintTags.cxx) not all the tags are printed and for accuracy in the output there isn't the tag "SequenceOfUltrasoundReagions" that interest me. But I know that in the file which I run this tag is present.
How can I access to this tag?
I hope I was understandable.
In particular the piece of code is:


typedef itk::MetaDataDictionary DictionaryType;
	const DictionaryType & dictionary = dicomIO->GetMetaDataDictionary();
	typedef itk::MetaDataObject< std::string > MetaDataStringType;
	DictionaryType::ConstIterator itr = dictionary.Begin();
	DictionaryType::ConstIterator end = dictionary.End();

	while( itr != end )
    	{
    		itk::MetaDataObjectBase::Pointer  entry = itr->second;

    		MetaDataStringType::Pointer entryvalue = dynamic_cast<MetaDataStringType *>( entry.GetPointer() );
	
    		if( entryvalue )
      		{
      			std::string tagkey   = itr->first;
      			std::string labelId;
      			bool found =  itk::GDCMImageIO::GetLabelFromTag( tagkey, labelId );
      
      			std::string tagvalue = entryvalue->GetMetaDataObjectValue();
      
      			if( found )
        		{
        			std::cout << "(" << tagkey << ") " << labelId;
        			std::cout << " = " << tagvalue.c_str() << std::endl;
				if (tagkey == "0018|6011")
					std::cout << "\n\nTROVATO!!!!!\n\n";
        		}
      
      			else
        		{
        			std::cout << "(" << tagkey <<  ") " << "Unknown";
        			std::cout << " = " << tagvalue.c_str() << std::endl;
        		}
      		}

    		++itr;
    	}



Thank you vary much
Edoardo
