Re: [Gdcm-hackers] Problem with CStore while trying to store Explicit files in the PACS server.

[Petchirajan J <pet...@in...>]

Dear Mark,Thanks for your response.I am searching for the interface CompositeNetworkFunctions in GDCM. I can't find this interface in the gdcm. could you please tell me where the CompositeNetworkFunctions interface is present?And I am trying to convert the implicit image to explicit image usinggdcmFileExplicitFilter class. The code i used is given below.gdcm::Writer w;w.SetFileName("D:\\ExplicitImg.dcm");gdcm::File &f = w.GetFile();f.SetDataSet(implicitDataSet);gdcm::FileMetaInformation &fmi = f.GetHeader();const char *tsuid = gdcm::TransferSyntax::GetTSString( gdcm::TransferSyntax::ExplicitVRLittleEndian );gdcm::DataElement tsDE( gdcm::Tag(0x0002,0x0010) );tsDE.SetByteValue( tsuid, strlen(tsuid) );tsDE.SetVR( gdcm::Attribute::GetVR() );fmi.Clear();fmi.Replace( tsDE );fmi.SetDataSetTransferSyntax(gdcm::TransferSyntax::ExplicitVRLittleEndian);w.SetCheckFileMetaInformation( true );gdcm::FileExplicitFilter fef;fef.SetChangePrivateTags(true);fef.SetFile(f);if( !fef.Change() ){thr
 ow gcnew Exception("Failed to convert to Explict Image"); }if (!w.Write()){throw gcnew Exception("Failed to write");}In the input implicit image i have some private sequence tags. I need to convert that private tags also to the explicit image. But, the VR for that tags are set "UN". For this problem i set Change Private Tag property true for gdcm::FileExplicitFilter. After that also i received the tag as Unknown format. Can you please help me to convert the implicit image with private tags to explicit image.

 s the result tomemory.This interface should allow you to avoid having to manipulateredundant tags (such as 0x8, 0x52).Your code would become something like:std::vector theFilenames;theFileNames.pushback("D:\\MRMONO216headSent.dcm");bool didItWork = CompositeNetworkFunctions::CStore("192.168.1.34",11112, theFileNames, "ANY", "DCM4CHEE");for the first part, and for the second part:theKeys.pushback(std::makepair(gdcm::Tag(0x8, 0x18),"1.2.840.113619.2.1.3352.1015047400.4.3.834485381"));BaseRootQuery* theQuery =CompositeNetworkFunctions::ConstructQuery(gdcm::ePatientRootType,gdcm::EQueryLevel::eImageOrFrame, theKey, true);std::vector theDataSets =CompositeNetworkFunctions::CMoveToMemory("192.168.1.34", 11112,theQuery, 11111, "ANY", "DCM4CHEE");delete theQuery;And then you can compare the results of the retrieved data set(s) withthe ones you sent over.We added this interface over the one you're using to make the processof using gdcm networking functions easier.I hope this helps wh
