Tracking changes

List changes

Whenever Orthanc receives a new DICOM instance, this event is recorded in the so-called Changes Log. This enables remote scripts to react to the arrival of new DICOM resources. A typical application is auto-routing, where an external script waits for a new DICOM instance to arrive into Orthanc, then forward this instance to another modality.
