Material/Methods: Network/IT configuration:

Within GC Australia, each state hosts an independent MIMpacs database on a virtual machine environment. User MIM clients are accessed via Citrix hosts. Additionally, each state hosts a MIM Contour ProtegeAI (CPAI) server, used for auto-segmentation using anatomical site specific artificial intelligence models. Incoming imaging series pass through the MIM Assistant service. The Assistant service allows the user to configure rules whose automated actions (e.g. CPAI auto-segmentation) are triggered based on searching incoming DICOM header information. System administration: Practical governance of MIM is administered via a national working group. Key roles of the working group include alignment of national workflows, testing and deployment, stakeholder communications and document management. Figure 1 gives a high level framework of how communications are handled. MIM users raise issues or suggestions with their state MIM administrators and log requests via Smart-sheet forms on an intranet share-point link.

Workflow development A major component of MIM governance includes development and standardisation of scripted workflows. Figure 2 shows an example where MIM integrates with end to end workflow automation. MIM organises registration, standardisation of structure naming conventions and data presentation. Finalized data, including the PlanCT and structures, are exported to Hermes (a DICOM router developed by Lumonus) where they are validated and linked to clinician selected patient care plan prescription (GenesisCare RO Portal). This comprehensive patient plan information is processed by a planning automation engine, utilizing Monaco or Eclipse application programming interfaces to execute automated planning.
