Scan the chart
Capture on behalf of a parent using on-device edge detection, crop, and perspective correction.
For nurses, CHWs, pediatricians, and clinics
Structured growth records with a visible verification trail.
NeoScan is designed to digitize MOH growth charts, support provider review, surface rule-based anomalies, and share traceable reports within strict role permissions.
Clinical workflow
From chart capture to acknowledged review.
Verify extraction
Review age, weight, or height values before committing the record. Overrides are logged.
Review the history
Inspect WHO reference curves, historical measurements, and any unacknowledged flags.
Document action
Acknowledge the flag, create a report, or initiate the specified referral workflow.
Maintain traceability
Create, read, update, share, and override actions remain visible in the immutable audit trail.
Work through outages
Queue scans offline and synchronize them chronologically when network access returns.
Verification screen
Automation proposes. A person confirms.
The record is not designed to pass silently from image inference into the clinical history.
Every extracted measurement is shown for review. Changes carry a manually verified state and audit event.

Rule-based review
Flags point to records that need attention.
The anomaly engine is specified to detect a drop across two or more major percentile bands and reject mathematically impossible growth rates.
Warning · unacknowledged
Growth trend needs review
Weight moved from above the 50th percentile to below the 15th percentile between consecutive visits.
Automated flag. Clinical interpretation required.
Provider actions
- Compare with source
Check the scan and verified values against the paper chart.
- Review context
Assess the growth history and available clinical information.
- Acknowledge
Record whether the flag has been reviewed.
- Refer when appropriate
Use the specified referral or secure report pathway.
Access model
Defined roles protect record boundaries.
Clinic access depends on a registered clinic token and explicit parental consent. Provider accounts are specified to use MFA.
Assigned records only
Providers can access records shared with their clinic. They cannot edit parent-entered birth date, sex, birth weight, or gestational age.

CREATE
Growth record added from scan.
OVERRIDE
Weight changed from 5.8 kg to 5.3 kg.
SHARE
Report generated after recorded consent.
Auditability
Every sensitive action leaves a record.
The backend design specifies write-once activity logs that cannot be edited or deleted by any user role.
Each entry includes user ID, UTC time, IP address, action type, changed fields, and before/after state where relevant.
Reports and referrals
A portable record for specialist review.
The specified password-protected PDF brings together growth entries, review flags, the WHO chart, and original scan images. A clinic can also initiate the proposed telehealth referral workflow.
Not in this version: real-time telemedicine video calls and national HMIS integration are outside the SRS scope.
Included
- Verified growth measurements
- WHO reference visualization
- Anomaly flag history
- Original chart scans
- Manual override status
Immunization administration requirements
Immutable completion records with clinical context.
The planned module restricts administration recording to authenticated providers and requires date, batch number, provider identity, and facility.

Pentavalent 2Sequence checkDue
Clinical exceptionReason requiredDeferred
Completed entries are locked; elevated administrator corrections must remain auditable. Future administration dates are rejected. The SRS scope summary separately calls immunization tracking out of scope, so this module needs formal scope reconciliation.
Clinical validation
Workflow fit and clinical relevance still require study.
NeoScan is an academic prototype. Its stated performance and availability figures are targets for testing, not completed validation outcomes.
- Digitization accuracy
Compare extracted values with known ground-truth chart coordinates.
- Clinical review
Evaluate whether the presentation supports safe interpretation.
- Usability
Assess parent and provider workflows in the intended context.
