Configuring the presentation contexts accepted by a DICOMInput node

After you add a DICOMInput node to a message flow, you can configure the node with a specific set of presentation contexts by using a configurable service.

Before you start:

You must have an existing application or library in which to store your configurable service, see Creating an application and Creating a library in the IBM® Integration Bus product documentation.
You must have a message flow that contains a DICOMInput node, see Using data from DICOM images in message flows.

Using a configurable service, you can configure the DICOMInput node with the presentation contexts that are made available to the Service Class User (SCU) that is sending the DICOM images. A presentation context specifies a service that is available to a connecting application. Each presentation context is associated with a transfer syntax group that lists the preferred data transfer formats for that service. If you are routing the DICOM images to several DICOM applications, then you should choose a set of presentation contexts for the DICOMInput node that is compatible with all the possible endpoints. Otherwise, the DICOMInput node might receive images that cannot be transferred onto one or more destination endpoints.

Note: If no configurable service is set for the node, then it defaults to a pre-defined set of presentation contexts. For information about the default set of presentation contexts, see Default presentation contexts used by DICOMInput node.

Use the following tasks to create and edit your configurable service and configure your DICOMInput node.

Create configurable service

To create a new configurable service for a DICOMInput node, complete the following steps.

From the IBM Integration Toolkit menu, click File > New > Other. A window opens in which you can select the wizard.
From the Healthcare folder, select DICOM Input Node Configurable Service and click Next. The New DICOM Configuration dialog opens.
Enter the name of an existing application or library, or click Browse to select one from a list.
Accept the default name for the configurable service (DICOM.configurableservice), or enter a new name (ensuring that it has an extension of .configurableservice).
Click Finish. The configurable service is created in the Other Resources folder of the specified application or library and the configurable service editor opens.
If you do not want to edit the service, click File > Close.

You have created a configurable service for a DICOMInput node.

Edit existing configurable service

If the configurable service is not already open in the configurable service editor, complete the following steps.
1. From the Broker Development perspective, locate the application or library where the configurable service is stored.
2. Open the Other Resources folder and double-click the configurable service that you want to edit. The configurable service editor opens and the list of available presentation contexts and transfer syntax groups is displayed.
Optional: Amend the list of presentation contexts using the associated Add, Edit and Delete buttons.
Optional: Configure the preferred order of presentation contexts using the associated Move Up and Move Down buttons. Ensure that your preferred presentation contexts are at the top of the list.
Optional: Amend the transfer syntax groups using the associated Add, Edit and Delete buttons.
Note: You cannot delete a transfer syntax group if it is being used by any of the presentation contexts.
Optional: Configure the preferred order of transfer syntaxes using the associated Move Up and Move Down buttons. Ensure that your preferred transfer syntaxes are at the top of the list.
From the menu, click File > Close and then click Yes to save your changes.

You have edited the presentation contexts and transfer syntaxes associated with the DICOMInput node configurable service.

Configure DICOMInput node by using existing configurable service

To configure your DICOMInput node by selecting an existing configurable service, complete the following steps.

In the Application development perspective, double-click the message flow that contains the DICOMInput node you want to configure. Your message flow opens in the message flow editor.
In the message flow editor, right-click the DICOMInput node and select Properties. The Properties view is displayed.
In the Properties view, click Advanced. The Advanced properties page is displayed.
In the DICOM Configurable Service field, enter the name of the configurable service you want to use. For example, DICOM.configurableservice.
From the menu, click File > Close and then click Yes to save the changes to your message flow.

You have configured the DICOMInput node with the presentation contexts and transfer syntaxes by using a configurable service.
