Four-Diagnostic Data Governance
Structured capture, terminology standardisation, quality validation and tiered archival of inspection, listening & olfaction, inquiry and palpation data — so four-diagnostic information becomes reviewable, comparable and durable.
How each of the four is captured
The four diagnostics differ in source and medium. Governance starts by giving each one an explicit capture standard and device condition, so data captured in different stores at different times remains comparable.
- Tongue and face imaging under standardised lighting and fixed geometry; repeat captures of the same patient are auto-aligned for trend review.
- Listening & olfactionVoice and breath cues are logged as structured fields; odour observations are entered by the assistant from standard options rather than free text.
- Pre-inquiry triggers structured follow-up questions from the chief complaint, converging symptom name, location, quality, temporal pattern, triggers and relief.
- 18-channel three regions / nine pulse positions capture at 1000Hz, supporting remote acquisition and pulse replay.
From raw capture to usable data
Captured data is not yet usable data. Before storage it passes terminology normalisation and quality validation; after storage it is held under sensitive-personal-information tiering.
- 01Terminology standardisationSymptom, location and quality fields map to an internal terminology set; synonyms are normalised so records stay searchable and countable.
- 02Quality validationCompleteness, device status and image / waveform usability are checked item by item, with re-capture prompts on failure.
- 03Structured archivalFour-diagnostic data is linked to the current case, forming a per-patient timeline for follow-up comparison.
- 04Tiered storage & accessHealth information is treated as sensitive personal information: separate consent, minimal collection, encrypted storage, role-based access.
Data governance is not diagnosis
The output of four-diagnostic data governance is structured, comparable capture data and assistive reference for the doctor. It does not constitute a diagnostic conclusion.
Syndrome determination, treatment-method selection and prescription are made by licensed TCM physicians within the licensed Internet Hospital; AI and devices never replace the doctor, never diagnose independently and never participate in prescription decisions.
