Clinical Decision Support • On-Premise Edge Node

Cancer detection AI that assists clinicians

Lumen brings serial labs, pathology slides, mucosal images, and routine CT together for clinician review inside your firewall. Qualified clinicians keep final authority.

Investigational clinical decision support suite • Operates under clinician supervision.

Multimodal Modalities

Clinical review workspaces across hospital diagnostic streams

On-premise ingestion from lab systems, PACS, scanners, and screening workflows, with departmental governance. AI scoring workers exist for lab trends and pathology; other modules offer review and capture, with AI in development.

  • Serial Lab & Biomarker Analytics

    OncoSignal

    Tracks serial hematology, chemistry, and tumor markers and flags trajectory shifts for clinician review. Data is processed on the hospital edge node.

    Serial BiomarkersHL7 / FHIR

  • Digital Pathology Whole-Slide Review

    OncoPath

    Gigapixel viewer for H&E and IHC biopsy slides, with AI assistance for pathologist review.

    Gigapixel WSIAI Assistance

  • Point-of-Care Oral Mucosal Screening

    OralScan

    Offline mobile capture of oral photographs, with specialist tele-review (send a case, get a review back) and referral tracking until the patient is seen. AI image analysis is in development.

    Offline MobileTele-review

  • Cervical Visual Inspection

    CerviScan

    Review workspace for VIA cervical images. Pap and LBC slide review is planned. AI inference is in development.

    VIA InspectionPap / LBC Planned

  • Opportunistic Thoracic & Abdominal CT

    CT Sentinel

    CT viewer with measurements, prior comparison, and segmentation overlay for radiologist review. Incidental nodule detection is in development.

    Thoracic & AbdomenAI in Development

  • CT Body Composition

    CT SentinelUpcoming

    Coming soon, as a pilot. From routine CT, measures muscle and fat areas at the L3 level and, when contrast conditions allow, liver, spleen and calcium, with trends across a patient's studies. Measurements are shown for clinician review only, as a research and clinician reference, and are not a diagnosis. No risk score is shown, and a review suggestion appears only where a site has an approved cut-off. Nothing is signed off or written back. Available only after a site enables it with approved parameters.

  • Breast Ultrasound Triage

    BreastScanUpcoming

    Upcoming in Phase 4. Assistive triage support for breast ultrasound review, off by default at every site and switched on per site only after approval.

Clinical Decision Pathway

Assistive pipeline with clinician review and sign-off

Standardized across diagnostic modalities to preserve established clinical protocols and governance.

  1. 1

    Secure On-Premise Ingest

    HL7/FHIR messages, DICOMweb images, whole-slide images, and encrypted mobile uploads are received on the hospital edge node.

    Local IngestDe-Identification
  2. 2

    Local AI Inference

    Where an AI worker exists, it runs locally with pinned model versions, fixed tiling, and recorded input hashes.

    Pinned ModelsLocal Compute
  3. 3

    Specialist Clinical Review

    Clinicians compare AI overlays with full-resolution scans and confirm or dismiss them. One timeline per patient shows labs, slides, images, and findings.

    Side-by-Side ReviewClinician Override
  4. 4

    Sign-Off & Optional Write-Back

    After clinician sign-off, reports can be written back to hospital systems. Connectors are configured per site.

Clinical Safety & Governance

Designed for clinical safety, data privacy, and fail-safety

Investigational software designed around clinical safety and governance.

  • Clinician in the Loop

    Assistive only. It does not auto-finalize diagnoses, make autonomous conclusions, or remove human review.

    Built to Support IEC 62304Human Decision

  • Tamper-Evident Audit Trail

    Inferences, overrides, and sign-offs are recorded in a hash-chained audit log, with write-once storage supported. Auditors can search and verify recorded actions.

    Write-Once OptionHash-Chained

  • PHI Stays on the Edge Node

    Identifiable patient records and raw imaging are designed to stay inside the hospital edge firewall. Names and IDs are stored apart from clinical data.

    Designed for DPDPLocal Firewall

  • Granular Clinical RBAC & Step-Up

    Deny-by-default access scoped by site, department, and role. High-consequence actions require step-up re-auth.

    Scoped RolesStep-Up Auth

  • Module Kill Switch

    Administrators can pause individual AI modules per site without disrupting hospital operations.

    Site GovernanceSafe-Stop

  • Fail-Open Clinical Reliability

    If an AI worker is offline, the interface is designed to show 'AI Pending' while human workflows continue.

    Clinical ContinuityFail-Open

  • Two-Person Approvals

    Threshold and model changes need a second approver.

    Second ApproverAudited

  • Triage Alerts

    Urgent flags reach the right team and must be acknowledged, by webhook or email.

  • Post-Market Monitoring

    Performance and incident tracking after go-live.

  • Fairness Monitoring

    Performance is checked across patient groups.

  • Consent-Gated Research Data

    Research datasets only include patients who consented.

  • Session Safety

    Sessions time out when idle, and signing out clears browser data.

Edge Architecture

Hospital-hosted edge node today, cloud control plane planned

Dedicated on-premise compute and records. Sites run fully on-premise today; a cloud control plane is on the roadmap.

Hospital Security Perimeter

Hospital Edge Node (On-Premise)

  • Encrypted local ingest, de-identification, and patient linker
  • Local inference workers for lab trends (CPU) and pathology (GPU)
  • Clinician review workspace with DICOM and whole-slide viewers
  • Hash-chained audit logging and granular role-based access control
  • Every model version is registered, signed and can be rolled back.
  • Site administrators manage users, devices and calibration in one place.
Planned: signed releases and health telemetry only, no PHI
Planned Control Plane

Control Plane (Cloud, Planned)

  • Planned: signed model packages and software releases
  • Planned: fleet health monitoring and site configuration
  • Planned: India-region hosting, with no PHI stored
