Dicom Router > How it works

The Workflow Engine SCP port is used to listen for incoming DICOM communications. The port continuously waits for incoming requests and as they arrive, passes them onto the Workflow Engine.

If the Workflow Engine receives a C-STORE command, the images are dynamically written into the Workflow Engine Share, a general-purpose network share. To maintain continuity of the image groups prior to forwarding, the DICOM attributes are posted to the Workflow Engine database.

A successful response is sent to the source AET and the association is closed normally.

The Workflow Engine supports a set of rules that determine which AET will receive the command. These rules are setup via product configuration and include:

• The NET that's within the command is used in a database lockup to identify the target AET.
• The command is always sent to a specific set of AETs, a technique commonly referred to as Fan Out.
• Multiple sources are always forwarded to single target entity.

A Workflow Engine SCU port is opened and the DICOM command is sent to the target AET(s), applying any pre-defined controls and necessary translation. If the association is successful, the port is closed normally and the images are removed from the Workflow Engine Share and the database. If the association is interrupted, subsequent attempts are periodically repeated until the images are successfully forwarded.
