Dicom Spooling > How it works

Replay
Listen
The SilverBack 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.

New Images
If the Workflow Engine receives a C-STORE command, the images are dynamically written into the SilverBack Engine Share. The DICOM attributes for these images are then posted to the Workflow Engine database. This step provides rapid, efficient, on-demand search capabilities for these images at any time.

The source AET receives a successful response. and the association is closed normally.
Latency
After the Workflow Engine receives each image, a series timer is restarted. Once the timer expires, the series can be sent. The timer duration is set through product configuration.
Send Images
Once the latency period has expired for an image series, the Workflow Engine SCU port is opened and an association is established with the target AET. All images for the oldest series are sent within the same association.

If the association is successful, it is closed normally and the images are removed from the Workflow Engine Share and database. If the association is interrupted, after a waiting period, the series is sent again in its entirety until it is successful.
