# Process Starts with Path 1 Load Setup FHIR bundles → FHIR. Guideline PDF → vectors. Report sentences → vectors. 2 Trigger HL7 order or MDT list HL7 ORM^O01 → production → SDA3 → ServiceRequest 3 Case build Collector opens a case API reads FHIR → candidates and status → LLM → Task, Composition 4 Collector actions Click in the UI Review → Basic. Approve → Task + Communication. Re-judge → Basic. 5 Images arrive PACS feed row CSV → production → PATCH ImagingStudy 6 Search Patient picker, timeline Picker: SQL on pacs.*. Timeline: vector search. 7 MCP Q&A MCP client question Agent ↔ LLM. Agent runs pacs-mcp tools → FHIR and SQL.
Origin Content Dataset Pseudonymized FHIR bundles and a PACS availability CSV from the hackathon Simulated HL7 orders, MDT list, other hospitals, insurer statement data. FHIR tag simulated.

The agent is the MCP client. pacs-mcp reads the Composition that the API wrote.
Call When Sends Find mentions Case build, per report not yet cached Text and date of one report ePACS match New place name in a report Place name and 15 facility names Judge case Case build, re-judge Case JSON. Tool results: guideline chunks, the patient’s report sentences. MCP agent A question Question. Tool results: FHIR resources, case summary, report sentences.
Patient text goes only to an EU Data Zone model. The API refuses other models. Embeddings run on a local model in the API container, so report text goes to no embedding service.
