PACS Storage Server Demo Rules Add-in

The Rules Add-in allows scripts to interact with the DICOM Server request/response pipeline. Healthcare facilities that need an automated method for moving DICOM objects can use the Rules Add-in and the Main PACS Framework Server (L20_PACS_SCP32). Typical uses of this add-in are to pre-fetch certain types of images (i.e. modality and performed procedure) to certain specialty workstations (radiology reading station, 3D Visualization station etc.) or to forward images to an on call radiologist or specialty department. Additionally, if DICOM datasets require special tags to be added before storing this can also be accomplished with the Rules Add-in.

The new Rules Add-In is a replacement for the DICOM Router Add-In. It has all the functionality of the previous add-in plus more options. It allows the user to write VB code that responds to events generated by the server. For instance, you can write a script that performs a specific action when a C-STORE request is received. The Rules Add-in also provides script functions for ready-made actions (route, move, caching, etc.).

Configuration

The Rules Add-in provides the following configuration dialog:

The configuration dialog consists of three tabs.

Script - Provides script configuration options and adds scripting rules to the add-in.
Manual Resends - Provides configuration options for resending requests that have failed during a store or move operation.
Details - Displays version information about the Rules Add-in.

Script Tab

Rules group

The Rules group allows you to add rules, delete rules and set the AE Title used during a C-MOVE-REQ. The following commands and actions are available from this group:

Add Rule - Add a new rule to the Rules Add-in.
Delete - Delete the currently selected rule. If the rule has been saved to a disk the corresponding file is also deleted.
AE Title - The AE Title to use for a script initiated C-MOVE-REQ.
References - Adds DLL and namespace references available to all the scripts in the Rules Add-in.

When the reference button is clicked the following dialog is displayed:
- References
  
  Lists the assembly references that will be included in the script.
  - Add an assembly reference
  - Delete the selected assembly reference
- Namespaces
  - Allows namespaces to be added to a list of namespaces that will be included in the script. If a namespace isn't available when trying to create the script an error will be generated.

Rule Definition group

The Rule Definition group allows editing of the script for a specified rule. The following actions are available in this group:
