# Micro-X: Real-Time Medical Device Interface

How National Digital built Micro-X an offline-capable, real-time interface for next-generation x-ray equipment using Nuxt.js, Apollo and MQTT.

## An interface that keeps working when the network doesn't

How National Digital built Micro-X an offline-capable, real-time interface for next-generation x-ray equipment using Nuxt.js, Apollo and MQTT.

## Architecture Diagram

- **Channels & edge** — Operator devices
- **API & integration** — Apollo GraphQL
- **Applications & workflows** — Nuxt.js operator UI
- **Data platform** — MQTT device messaging
- **Hosting & delivery** — Monitoring, backups

## Micro-X by the numbers

Figures reflect National Digital's engagement with Micro-X and are drawn from project delivery records; some operational details are summarised for publication.

- **Connectivity modes supported: Online + offline** — The interface provides real-time control whether or not the equipment has an active network connection. _(Source: National Digital project records, 2025)_
- **Data protocol: MQTT event-driven** — Device state updates flow through an MQTT event-driven architecture for instant control response. _(Source: National Digital project records, 2025)_
- **Deployment contexts: Medical + aviation** — The same interface architecture serves both medical and aviation x-ray deployment environments. _(Source: National Digital project records, 2025)_

**Methodology:** Based on National Digital project delivery records for this engagement; selected figures are indicative and rounded rather than independently audited metrics.
