Inobitec DICOM Viewer

12.2. Set Up PACS Server Connection

In this window you can set up the connections with the applications, which can exchange data with the Viewer using the DICOM protocol. In this case the Viewer can take on the role of a PACS server and other applications will be clients, and vice versa. Because most of the applications with which connection can be established can take on the role of a PACS server, connections with them set in this window, regardless of whether they will be in relation to the Viewer of the servers or clients.

To open the window to connect to PACS servers, select the Network menu and the Server list item, or press Ctrl+S. The dialog box shown in Fig. 12.2 will pop up.



The Viewer allows you to download several series from the PACS server at the same time, making several parallel connections to the PACS Server. However, not all PACS Servers support a large number of simultaneous connections and this leads to errors when downloading data. Setting the maximum number of connections is described in 15.4.4. This setting applies to all PACS Servers.

12.2.1 Add PACS Server

To add a new PACS server:

  1. Click the PIC button.
  2. Enter the server name in the Server nickname field.
  3. Enter a comment in the Server description field. This field may be left blank.
  4. Select DICOM from the Server type dropdown menu.
  5. Select target mode from the Server mode dropdown menu.
  6. Select the server charset from the Character set dropdown menu.
  7. In the Client name (SCU) field enter the value specified in Section 12.1.1 in the AETitle field.
  8. In the Service name (SCP) field enter the name of the server that the PACS server is installed on.
  9. In the Server host name or IP field enter the server name or IP address.
  10. In the Server port field enter the server port to accept connections by the DICOM protocol.
  11. To save the information without closing the window, click OK.
  12. To save the information and close the window, click Save.
  13. To close the window without saving the changes, click Cancel.

    The required information can be obtained from your system administrator. Other PACS servers are added in a similar way.

If you have several servers on your list, you can assign a server that will be active by default when starting the Viewer. To do this, check the Default server box in the server connection settings.

If another default server is already assigned, its box will be unchecked when you assign a new server.

If this server is also a client in relation to the Viewer, it is necessary to allow it to exchange data. To do this, check the box Allow C-FIND and C-MOVE. Configure the client application in accordance with the User Manual of this application. Configuring the connection of two applications Inobitec DICOM Viewer described in section 12.2.3.

To delete a server from the list, click the PIC button. Attention! After you click this button, the deletion cannot be undone.

12.2.2 Check PACS Server Availability

To check if the server is available, click the PIC button in the PACS server connection window. If the server is available, the system will return the following message: Server network status: Online (Fig. 12.3).



Otherwise the following message will be returned: Server network status: Offline (Fig. 12.4). The error details will be displayed below.



If a message similar to the one shown in Fig. 12.4 appears, it most likely means that the Server host name or IP or Server port fields are filled in incorrectly, or the target PACS server is not running.

12.2.3 Configuring the connection of two application Inobitec DICOM Viewer

Suppose that the Viewer #1 takes on the role of a PACS-server and Viewer #2 takes on the role of a client.

Parameters of the Viewer #1:

  • AETitle: VIEWER-SERVER;
  • IP: 192.168.1.101;
  • Port: 3001.

Parameters of the Viewer #2:

  • AETitle: VIEWER-CLIENT;
  • IP: 192.168.1.102;
  • Port: 3002.

To configure server:

  1. Enable and set up the DICOM service (section 12.1.1), set AETitle as VIEWER-SERVER, set Port as 3001.
  2. Add the client on the window for Set Up PACS Server Connection (section 12.2.1). Set the following parameters for the fields:
    • for field Server type — DICOM;
    • for field Server mode — C-MOVE;
    • for field Client name (SCU) — VIEWER-SERVER;
    • for field Service name (SCP) — VIEWER-CLIENT;
    • for field Server host name or IP — 192.168.1.102;
    • for field Server port — 3002;
    • check the box Allow C-FIND and C-MOVE.

    Now the Viewer #1 is ready to accept incoming connections from the client with the AETitle = VIEWER-CLIENT, IP = 192.168.1.102 and port=3002.

To set up client:

Add the server on the window for Set Up PACS Server Connection (section 12.2.1). Set the following parameters for the fields:

  • for field Server type — DICOM;
  • for field Server mode — C-MOVE;
  • for field Client name (SCU) — VIEWER-CLIENT;
  • for field Service name (SCP) — VIEWER-SERVER;
  • for field Server host name or IP — 192.168.1.101;
  • for field Server port — 3001;

Now the Viewer #2 is ready to connect to the server with AETitle = VIEWER-SERVER, IP = 192.168.0.101 and port=3001.

If you enable and set up the DICOM-service and check the box Allow C-FIND and C-MOVE for VIEWER-SERVER server on the Viewer #2 settings, the Viewer #2 will be able to take on the role of server and the Viewer #1 will be able to take on the role of client. Thus the Viewer can take on the role of a client and a server simultaneously.
