C-FIND and Cyrillic charset.

[Семён Дунаев]

Hello!

I Am completly new in programming and in Dicom.

First i would like to say a big thx for Fellow Oak DICOM Team. realy awesome instrument!

-------

Please help me to understand how to set encoding in C-FIND.

i know how to Add DicomTag with Cyrillic encoding, but cant understand how to Get with C-FIND.

for example:

rename patient and send to Orthanc:

var file = Dicom.DicomFile.Open(@"file.dcm");
 file.Dataset.Remove(Dicom.DicomTag.PatientName);
 file.Dataset.Add( new DicomPersonName(
 DicomTag.PatientName, DicomEncoding.GetEncoding(
 "ISO 2022 IR 144"), "Иванов Иван Иванович")
 );

 file.Save(@"file_renamed.dcm");

 var client = new DicomClient();

client.AddRequest(new DicomCStoreRequest(@"file_renamed.dcm"));

client.Send("127.0.0.1", 12345, false, "SCU", "ANY-SCP"); 

C-FIND:

 

var cfind = DicomCFindRequest.CreateStudyQuery(patientId: "*");
             cfind.OnResponseReceived = (DicomCFindRequest rq, DicomCFindResponse rp) =>
             {
             Console.WriteLine("PatientName: {0}\n", rp.Dataset.Get<string>(DicomTag.PatientName));
             
             var client = new DicomClient();
             client.AddRequest(cfind);
             client.Send("127.0.0.1", 12345, false, "SCU", "ANY-SCP");

and i got something like "?????? ???? ????????"

How can i Get PatientName with right encoding?

thx a lot.

First of all, are you sure that the Orthanc server is interpreting the file correctly? If you open file_renamed.dcm with a fo-dicom based tool such as DICOM Dump, are you still seeing only question marks?

You might want to try a different encoding, most preferably "ISO IR 192" (UTF-8). Does that work?

First of all, are you sure that the Orthanc server is interpreting the file correctly?

Yes. Orthanc web interfaces show it correctly. 

 If you open file_renamed.dcm with a fo-dicom based tool such as DICOM Dump, are you still seeing only question marks?

No. When i dump file_renamed.dcm or when i recieve it from Orthanc and dump - it looks correctly too.

You might want to try a different encoding, most preferably "ISO IR 192" (UTF-8). Does that work?

No. Doesnt work. i mean - when i dump or recieve and dump - its look ok, but with web interface or with C-FIND i see question marks.

So:

You send the image with the Cyrillic name to Orthanc, and Orthanc tools display the name correctly?

Then you use C-FIND to query files from the Orthanc server, and the name in the response is displayed with question marks?

What happens if you use another tool/library than fo-dicom to query Orthanc, is the name then displayed correctly?

After a lot of experiments  i found a bug in Orthanc, that was fixed in 1.2 version.

I compiled it from the git and now it works!

but i have an offtop question:

can you help me with c-find output into ListView?

[Anders Gustafsson Cureos AB]

What I would do is to populate a list of C-FIND responses in the OnResponseReceived event handler, and then populate my ListView control with certain properties of the C-FIND response. Not sure if that is what you are asking. Are you using Windows Forms or WPF?

[Семён Дунаев]

Windows Forms.
All that i need is an example with simple Form: listview with 2 columns - patientName and studyDate. Its enaugh for me to understand how to output from cfind to listview.

[Anders Gustafsson Cureos AB]

OK. I don't have anything straight away, but maybe someone else in the community has a similar sample? You can also post your question in the fo-dicom forum on Gitter, here.

Understood!

Thx for the help!
