Mapping RequestedProcedureDescription in StudyDescription in CFIND response

Hi there,

I’m writing here for an unconventional problem.
In a few words, our PACS system has some “StudyDescription” equivalent information in the tag 0032,1060 Requested Procedure Description

We are able to do the CFIND query with the 0032,1060 tag and get this data in CFind answer, no problem about that.

My problem is, rather than having to expose the 0032,1060 tag in the answer in my frontend (orthanctoolsjs) I would want to map this data to the traditional “study description” answer of orthanc.

We are here in a very particular problem, for historical reason we have many dicom answer in which the “real” StudyDescription is in Requested Procedure Description.

So I would want to know :

For the Query CFIND we have OutgoingFindRequestFilter accessible in lua scripts that allow us to modify the CFIND request before being sent to DCMTK (and thus act as a request middelware).

I would want to know if there are such a function to be able to modify DCMTK Dicom Answer’s before being outputed by Orthanc Rest APIs (and so having a response middelware).
This way I would be able to map the 0032,1060 tag into the StudyDescription response tag.
This way I would be able to hide this incorrect input from our PACS to the orthanc application.

Best regards,

Salim

Hello,

This is definitely possible by adapting the 3 calls to “answers.Add(result)” in the following file:
https://hg.orthanc-server.com/orthanc/file/Orthanc-1.7.4/OrthancServer/Sources/OrthancFindRequestHandler.cpp

One could indeed add a Lua callback to alter the “result” variable before it is added to “answers”. Unfortunately, I don’t have the time to do this adaptation right now.

Thanks sebastien for your anwser,
I will make an optional display of “RequestedProcedureDescription” in orthanc-tools-js and then we will see later for this lua callback,

Best regards,

Salim
