DICOM watch and report service using Orthanc and DIANA, packaged with docker-compose for [belena.io][] arm32v7 devices.
Configuration is handled through the services definitions, which can be passed as a file or as an environment variable to the DIANA service.
For a default reporting service that triggers every 3 minutes and reports all studies, set device environment variables for the following:
ORTHANC_PASSWORD=<password>
LOCAL_PACS_ADDR="pacs,<aet>,<addr>,<port>"
SPLUNK_HOST=<splunk host name>
SPLUNK_HEC_TOKEN=<registered hec token>Any other sensitive information should also be set via environment variables and saved in tmpfs volumes, if at all. If secrets are hardcoded into Docker image variables or files, they can be inspected in a stopped container.
To run more complex queries, modify the services.yml file "pacs" key. For example, the following service description would run every 10 minutes and return the accession number and patient id for any new non-con head CT's (with a matching description) from the prior 30 minutes. See the DIANA ObservableProxiedDicom api for parameters.
