findscu on Orthanic

[Christopher Petty]

Just found Orthanic today ( nice package ) as i needed to setup a virtual scanner for some offline testing.

i built Orthanic on scientific linux, configured, started and pushed some data in from a remote system using storescu

Maybe i missed, or mis-understood this, but how can i query the Orthanic database from a that same remote machine using findscu ?

I can query my scanner with something like the following:

findscu -aet NAME -S -k StudyID="12345" -k SeriesNumber="3" host.ip DCMPORT

Is this possible with my instance of Orthanic

Thanks,

-chris

Dear Christopher,

Thanks for your interest in Orthanc. It is indeed possible to query Orthanc from findscu, but you also have to set the "QueryRetrieveLevel" tag (0008,0052) in your call to findscu. Here is the correct call in your case:

# findscu -aet NAME -S -k "0008,0052=STUDY" -k StudyID="*" -k SeriesNumber="*" localhost 4242

You will find attached the corresponding configuration file for Orthanc. I have only changed the default "DicomModalities" section as follows:

  "DicomModalities" : {

    "test" : [ "NAME", "localhost", 104 ]

  }

"NAME" corresponds to the argument you used for the "-aet" option.

HTH,

Sébastien-

Great, thanks for the reply, this is going to be extremely helpful

To follow up ... is is possible that after performing a find request .. i can perform a move request and pull the data ?

with my findscu calls working in the modified config, i would expect to replace findscu with movescu ( at least this is my experience when querying our mr scanner as long as i have configured my aet ).

# findscu -aet NAME -S -k QueryRetrieveLevel=SERIES -k StudyID="12345" -k SeriesNumber="6" orthanc.host 4006

returns a valid series

# movescu -aet NAME -S -k QueryRetrieveLevel=SERIES -k StudyID="12345" -k SeriesNumber="6" orthanc.host 4006

returns an "Error Failed - Unable to process" log

with this from the server trace:

My push commands to "dicom.example" work, when going through the web interface and i've tries many different iterations of:

["MOVESCU","queryhost.example",port]

["sl6-vm2","queryhost.example",port]

["new-aet","queryhost.example",port]

etc

OK, i realized after looking at the OrthancMoveRequestHandler.cpp src that i need to specify by SeriesIntanceUID if i am querying on a series level ... However now i'm just managing to push the data to my own Orthanc server :)  and not actually pull it to my new machine

I eventually got this to work with 2 entries 

# movescu -aem DEST -aet SRC -S -k QueryRetrieveLevel=SERIES -k SeriesInstanceUID="1.2.840.###########" orthanc.host 4006

"test"  : [ "SRC","localhost",4006 ],

"tesla" : [ "DEST","dest.example.edu",4006]
