Hermes DICOM Router

Important: Development of the Hermes DICOM router has been discontinued. Please take a look at the successor project "mercure DICOM Orchestrator": https://github.com/mercure-imaging/mercure

A flexible DICOM routing solution based on DCMTK toolkit. It consists of multiple separate modules / applications that handle different steps of the routing procedure.

Receiver

The receiver listens on a tcp port for incoming DICOM files. Received files are run through a preprocessing procedure during which DICOM tag information is extracted and stored in a json file.

Router

The router module runs periodically and checks

• if the transfer of a DICOM series has finished (based on timeouts)
• if a routing rule applies

If both conditions are true, the DICOM series is copied into separate outgoing folders for each target. If no rule applies, the DICOM series is placed in the discard folder.

Dispatcher

The dispatcher module runs periodically and checks

• if a transfer from the router has finished
• if the series is not already being processed
• if at least one DICOM file is available

If the conditions are true, the information about the DICOM target node is read from the target.json file and the images are sent the this node. After the transfer, the files are moved to either the success or error folder.

Cleaner

The cleaner module runs periodically and checks

• if new series arrived in the discard or success folder
• if the move operation into these folder has finished
• if the predefined clean-up delay has elapsed (typically 7 days)

If these conditions are true, series in the success and discard folders are deleted.

Webgui

The webgui module provides a user-friendly web-based interface for configuring, controlling, and monitoring the DICOM route solution.
