    • IP
    • port
    • AETITLE
    • CALLED AETITLE

  • Set the internal values specifying the remote PACS host according to here.

Running an actual PACS Query

Now we are ready to perform an actual PACS Query.

It might first be necessary to set the internal findscu variable. The default is /usr/local/bin/findscu however on non-containerized systems it might /usr/bin/findscu.

pfurl   --verb POST                             \
        --raw                                   \
        --http ${HOST_IP}:4055/api/v1/cmd       \
        --jsonwrapper 'payload'                 \
        --msg '{  
            "action": "internalctl",          
            "meta": {
                "var":     "/bin/findscu",
                "set":     "/usr/bin/findscu"
            }
        }'
pfurl   --verb POST                             \
        --raw                                   \
        --http ${HOST_IP}:4055/api/v1/cmd       \
        --jsonwrapper 'payload'                 \
        --msg '{  
            "action": "PACSinteract",          
            "meta": {
                "do":  "query",
                "on" : {
                   "PatientID": "LILLA-9731"
                },
                "PACS" : "orthanc"
            }
