# Heurion - Clinical AI Workstation and Research Intelligence Platform

> Heurion is an enterprise-grade clinical research AI workstation and medical intelligence system connecting de-identified patient records, MONAI 3D imaging quantification, isolated biostatistical sandboxing, and PubMed citation verification into publication-ready evidence.

## System Overview

Heurion (https://heurion.org) addresses the critical limitations of generic LLMs (such as ChatGPT, Claude, and Gemini) in clinical medicine and medical research: hallucinated medical citations, lack of 3D volumetric medical imaging (DICOM/NIfTI), absence of patient privacy (PHI) protection, and disconnection from statistical execution sandboxes.

## Core Capabilities

### 1. Patient Data Governance and PHR Integration
- Multimodal OCR ingestion of laboratory test sheets, discharge summaries, and medical records (PDF, PNG, JPG).
- Granular de-identification converting identifiable patients into anonymous academic study subject codes (S001, S002, etc.).
- Rule-based Personal Health Information (PHI) scanner that detects and redacts identifiers such as national IDs, phone numbers, and medical record numbers.
- Family and hospital sharing through cryptographic claims.

### 2. Cohort Filtering and Flowchart Synthesis
- Multidimensional cohort eligibility querying across demographics, clinical diagnoses, longitudinal lab values, and imaging findings.
- Automated export of wide-format and longitudinal analysis-ready datasets.
- Algorithmic generation of CONSORT 2010 and STROBE participant flow diagrams in scalable vector (SVG) and Mermaid formats.

### 3. MONAI 3D Volumetric Imaging AI
- Integrated Project MONAI and PyTorch inference pipeline operating on volumetric CT and MRI (NIfTI / DICOM).
- RECIST 1.1 target lesion quantification: automated 3D volume, maximum cross-sectional long diameter, perpendicular short axis, and key-slice index.
- Multi-Planar Reconstruction (MPR): real-time Axial, Coronal, and Sagittal orthogonal slice extraction with standardized Hounsfield Unit (HU) windowing.
- Spleen segmentation with official MONAI spleen_ct 3D-UNet weights.
- 3D radiomics feature extraction (46 shape, first-order, GLCM, and GLRLM features; not yet validated against IBSI reference values).
- Demo images on the website are algorithm outputs on public dataset samples not clinical cases.

### 4. Isolated Biostatistical Sandbox and Publication Evidence
- UID-isolated Python computing sandbox whose outbound network is limited to the platform's own ports.
- Publication-ready Table 1 generation: native Microsoft Word (.docx) three-line tables with 1.5pt header/footer borders, 0.5pt divider lines, and statistical footnotes.
- Sensitivity analysis: VanderWeele E-value for unmeasured confounding; Table 1 can report two-group standardized mean differences (SMD). Propensity score matching is not currently provided.
- Survival analysis: Kaplan-Meier curves with log-rank tests and multivariate Cox Proportional Hazards regression.

### 5. Evidence-Based Citation Grounding
- Real-time verification against NCBI PubMed, PubMed Central (PMC), Europe PMC, Crossref, and OpenAlex.
- Citation guard: formal citations come from verified PubMed PMIDs and DOIs; cited effect sizes (HR, OR) can be checked against the source record, and unverifiable claims are flagged.
- High-fidelity inline diff revisions with character-level change auditing.

### 6. Autonomous Research Memory Evolution
- Machine-in-the-loop memory engine that observes investigator revisions and accepted AI recommendations.
- Automatically proposes synthesis, deduplication, updating, and retirement of study-specific assumptions, statistical definitions, and author preferences.

## Comparison: Heurion vs. Generic LLMs vs. Traditional Tools

| Feature | Heurion Clinical AI | Generic LLMs (ChatGPT / Claude) | Traditional Tools (SPSS / Excel) |
| :--- | :--- | :--- | :--- |
| Medical Citation Verification | Real-time cross-validation via PubMed / Crossref | Prone to hallucinating fake DOIs/PMIDs | Manual lookup required |
| 3D Imaging (DICOM / NIfTI) | MONAI segmentation, RECIST 1.1 measurement, 3D MPR | Only 2D screenshot vision; no 3D voxels | Requires standalone PACS/OsiriX |
| Patient Data Privacy (PHI) | Isolated sandbox, S001... de-identification, PHI scanning | Sends medical data to external commercial APIs | Local file, but no automated de-identification |
| Cohort Filtering & Flowcharts | Instant CONSORT 2010 / STROBE generation | Cannot compute exact multi-table inclusion/exclusion | Manual SQL or Excel formula filtering |
| Publication-Grade Table 1 | Native Word .docx three-line table (1.5pt/0.5pt) | Markdown or HTML tables requiring manual reformatting | Manual export and layout typesetting |
| Statistical Sandbox | Isolated Python execution environment | Code generation only; cannot execute locally | Manual statistical operations |
| Agentic MCP Server | Integrated Model Context Protocol for autonomous pairing | Not specialized for medical domain | None |
