Filter some params of a C-FIND on the Orthanc side

[Raúl Alexis Betancor Santana]

I need to filter one param of a C-FIND query that a DICOM client sends.

Thats because a very good Dicom Client that wants to use on the hospital, but it supposed to only work with 'their' PACS, making some test, I have seen that the only diference beetween what they send and a 'normal' C-FIND, it's that they add to the query this:

OrthancFindRequestHandler.cpp:214]   (5555,0010)  PrivateCreator = AETMED RETRIEVE INFO

Is there any way to tell Orthanc to ignore that Param ?

Best regards

[Marc Delpont]

Why not a Lua function for debuging, filtering and/or tuning a received C-FIND query before applying it ?

It could be applied to both Q/R and Worklist C-FIND queries.

[Robert van Ommen]

That would be really nice!

That way you do not have to make/compile a new Orthanc version for every "non conforming" DICOM modality.

[Sébastien Jodogne]

I found Marc's idea so nice that I have immediately implemented it:

https://bitbucket.org/sjodogne/orthanc/commits/512b6e76f5311cfbd71c6d3ceb50671f1ffb5b74

Here is a sample Lua script that would solve Raúl's issue:

function IncomingFindRequestFilter(source, origin)

   PrintRecursive(source)

   PrintRecursive(origin)

   local v = source

   v['5555,0010'] = nil

   return v

end

[Marc Delpont]

Excellent !!!

[Raúl Alexis Betancor Santana]

Thats fantastic!! ... I'm testing it ...

I have never used lua scripts before, did I need to setup any option, more than declaring the script on the orthanc.json file ?

[Sébastien Jodogne]

Great ;)

You only have to declare the path to the Lua script in the section "LuaScripts" of the configuration file.

[Raúl Alexis Betancor Santana]

Done, but I don't see on the log any reference as the script been executed when the query come into the Orthan server

[Sébastien Jodogne]

It should, because of the PrintRecursive() that will write to the log.

Are you sure the "LuaScripts" section is properly configured? You should see a line "Installing the Lua scripts from..." in the log.

But when the query comes ... anything printed ...

What is the exact content of:

?

[Raúl Alexis Betancor Santana]

I highly suspect that you are not running the latest version of the mainline Orthanc. Please be sure to pull, update to the mainline branch, and to rebuild.

[Raúl Alexis Betancor Santana]

EUREKA!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Now an artificially closed Dicom Viewer, could be used with Orthan as PACS!!! ..

Awesome!, just Awesome man! ..

Thankssssssssssssssssssssss!

Jeje ..., ok ... that explains the lack of logs .. XDD

2015-12-11 17:57 GMT+00:00 Sébastien Jodogne <s.jo...@gmail.com>:

I pushed the change only 2 hours ago :)

So, this feature is only in the mainline and you will have to clone from BitBucket:

What's this awesome closed DICOM viewer? Still trying to decide what to deploy and would like to try it (even if it takes installing the lua script)
