  • IP
  • port

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"
            }
        }'
