Configuring DICOM Query/Retrieve

Starting with release 0.7.0, Orthanc supports DICOM Query/Retrieve (i.e. Orthanc can act as C-Find SCP and C-Move SCP). To configure this feature, follow these instructions:

  • Get the AET (Application Entity Title), the IP address and the port number of your DICOM client.
  • Add an entry in the DicomModalities section of your Orthanc configuration file to reflect these settings.
  • Restart Orthanc with the updated configuration file.
  • Symmetrically, in your DICOM client, configure an additional DICOM node corresponding to your Orthanc AET (see the DicomAet parameter of your Orthanc configuration, by default, ORTHANC), IP address et port number (cf. DicomPort, by default 4242).

If you encounter configuration problem with query/retrieve, please be sure to read the C-Move: Query/retrieve section.

Illustration: Ginkgo CADx

This section explains how to connect the Ginkgo CADx viewer to an Orthanc server, both running on the local computer. First, start Orthanc without specifying a configuration file (i.e. using its default configuration). Then, open the settings pannel of Ginkgo CADx:


Write down the AET and the DICOM port of Ginkgo CADx (in this case, respectively GINKGO_001 and 11112). Then, create a new DICOM node corresponding to Orthanc by clicking on the “New...” button, which raises the following dialog box:


Complete the highlighted fields with the default parameters of Orthanc, as shown in the screenshot. Do not forget to click on the “Test connection” button to make sure the C-Echo succeeds. Stop Orthanc, create a new configuration file, and declare Gingko CADx in the DicomModalities section, given the parameters you wrote down above:

// The list of the known DICOM modalities
"DicomModalities" : {
  "ginkgo" : [ "GINKGO_001", "localhost", 11112 ]

Restart Orthanc using this newly created configuration file, and you will be able to do query/retrieve from Gingko CADx through the “PACS Q/R” menu.
