LEADTOOLS Modality Worklist WCF and MPPS WCF

This topic explains how to use the LEADTOOLS Modality Worklist WCF demo, LEADTOOLS DICOM High Level Modality Worklist SCU Demo, and the LEADTOOLS MPPS WCF demo.

LEADTOOLS Modality Worklist WCF Demo

The LEADTOOLS Modality Worklist WCF interfaces provides to basic services for working with the LEAD Modality Worklist hosted by a PACS Framework Server.

• Modality Worklist Functions - These functions allow you to add, modify and delete records in the Modality database that relate to modality worklist functions.

• Modality Performed Procedure Step - These functions allow you to add, modify and delete records in the Modality database that relate to modality performed procedure step.

Perform the following steps to setup the LEADTOOLS Worklist WCF testing environment:

1. Run the PACSConfig tool to setup the servers for testing the WCF Worklist components. Make sure that the "Install Broker Host Add-in" checkbox is checked. This will install the Broker-Host to the Main Server. If there is a conflict with the port, make sure and change the Broker Host add-in port number.

   

2. After configuring the servers. launch the LEADTOOLS Pacs Server Manager Application (CSLeadtools.Dicom.Server.Manager_Original.exe). If the Broker Host was successfully installed you should see the following icon under AddIn Options when selecting L19_SERVER32. Double click the Broker Host icon to configure the broker host.

3. Double click on the highlighted icon (Broker Host) to set the configuration for the Broker Host. The CSPACSConfigDemo_Original.exe application has set this up to point to the default configuration file. If you need to change the configuration, double click on the folder icon to select a new configuration file. The configuration file is a standard .NET configuration file that contains settings for hosting a web service.

   

4. To start the broker host service you will need to start the main server. If you do not start the main server, the Start button will be disabled. If the server is not running, please exit the dialog and start the main server. When you re-launch the configuration dialog, the Start button should be enabled.

   

5. Click Start to start the broker host service.

   

6. The Stop and Restart options will be available once the Broker Host service has been successfully started. At this point, you are ready to run the Modality Worklist and Modality Performed Procedure set demos.

   In the scenarios below, the Worklist database dialog will be used to verify each step. You can access the Worklist database dialog by clicking on the "Worklist Configuration" Icon in the LEADTOOLS Service manager application.

   

7. Double clicking Worklist Configuration will display the following dialog:

   

   This dialog can be used to see the changes made using the worklist services.
