Evidence-Linked Radiology
NEXARAD
Evidence-linked imaging workflows with strict non-clinical demo boundaries.
Synthetic DICOM demo
PHI disabled
external AI off by default
Demo / Research / Not for Clinical Use
Problem
Medical imaging demos often skip the hard parts: PHI boundaries, DICOM plumbing, tenant isolation, object storage, report provenance, and clear labeling when something is research-only rather than clinical software.
System
OHIF/product frame with synthetic DICOM evidence and report provenance across Orthanc and MinIO.
Evidence
Demo / Research / Not for Clinical Use labels stay visible near every relevant claim. Idempotent `make seed` path and synthetic CXR fixtures.
Outcome
The founder-ready walkthrough can boot the full local demo (`make up`), seed visible research-only studies and draft reports, rehearse uploads, and keep AI providers and PHI disabled by default (`ALLOW_PHI=false`).
System
Non-clinical imaging stack
Browser clients call only the NexaRad API. PHI stays off; Orthanc and MinIO hold synthetic evidence.
Approach
I built a local stack with web, API, OHIF, Orthanc, MinIO, Alembic migrations, seeded non-PHI studies, synthetic upload smoke tests, demo/research safety defaults, and a rule that browser clients only call the NexaRad API.
Constraints
Not for clinical use. Synthetic evidence only; no diagnostic claims.
