In this window, you can set up the connections with the applications which can exchange data with the DICOM Viewer, using the DICOM protocol. In this case, the DICOM Viewer can take on the role of a PACS server and the other applications will be clients, and vice versa. Since most of the applications with which a connection can be established can take on the role of a PACS server, the connections with them are set up in this window, regardless of whether they will be servers or clients in relation to the DICOM Viewer.
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. 11.2 will pop up.
The DICOM 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 14.5.4. This setting applies to all PACS Servers.
To add a new PACS server:
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 DICOM 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 DICOM 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. The connection configuration of two "Inobitec DICOM Viewer" applications is described in section 11.2.3.
To make the server available to all the users, you need to check the Shared server (multi-user support) box for this server. To do that, you need to run the DICOM Vieweras an administrator. Otherwise the box will be inactive. The users that do not have the administrator privileges cannot change the public server settings or delete it.
To delete a server from the list, click the button. Attention! After you click this button, the deletion cannot be undone.
To check if the server is available, click the button in the PACS server connection window. If the server is available, the system will return the following message: Server network status: Online.
Otherwise the following message will be returned: Server network status: Offline.The error details will be displayed below.
Server is unavailable.
Connection request failed.
Failed to establish association
0006:0317 Peer aborted Association (or never connected)
0006:031c TCP Initialization Error: No error
If a message similar to the one shown below 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.
Let‘s assume that DICOM Viewer #1 takes on the role of a PACS-server and DICOM Viewer #2 takes on the role of a client.
Parameters of DICOM Viewer #1:
Parameters of the DICOM Viewer #2:
To configure the server:
Now, DICOM 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 a client:
Add the server in the Set Up PACS Server Connection window(section 11.2.1). Set the following parameters for the fields:
Now DICOM 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 the VIEWER-SERVER server in the DICOM Viewer #2 settings, then DICOM Viewer #2 will be able to take on the role of a server and DICOM Viewer #1 will be able to take on the role of a client. Thus, the DICOM Viewer can take on the role of a client and a server simultaneously.
