Send to the PACS and a copy to a VNA

Goal: modalities send once, to the router. Every study reaches the PACS as it was received, and a lossless JPEG 2000 copy reaches the VNA for long-term storage.

Before you start

• The PACS’s and the VNA’s host, port and AE title, and both set up to accept the router (its AE title ROUTES and every node’s address).
• The modalities’ calling AE titles and network.

Steps

1. Destination: PACS. Configuration › Destinations › Add destination: name PACS, host, port, called AE title. Leave Transfer syntaxes on the default. Save, then Echo.
2. Destination: VNA. Add VNA the same way. Under Transfer syntaxes, give it its own list: JPEG 2000 Lossless › As received. Save, then Echo and Test syntaxes to see what it accepts.
3. Source. Configuration › Sources › Add source: name Modalities, Calling AE titles CT*, MR*, DX* (one per line), Remote IP ranges the modalities’ network.
4. Route. Configuration › Routes › Add route: name Modalities to PACS and VNA, source Modalities, destinations PACS and VNA.
5. Point the modalities at the router: its DNS name, the listen port, AE title ROUTES.

Check it

• Send a study. On Monitoring you see it arrive, then two deliveries, one per destination.
• In History, open the study: each instance shows Delivered to both, the VNA’s in JPEG 2000 Lossless, converted from what was received.

Variations

• Only some studies to the VNA: a second source with a header condition (say Modality Equals CT|MR) and its own route above this one, sending to both; this route then sends the rest to the PACS only. See Routes.
• The VNA over a slow link: a schedule limiting it during the day; the PACS is not held up, since every destination has its own queue.
• Make sure the VNA has them: tick Request storage commitment on it, and the history shows Committed.
