IoT-enabled medical device interface with offline capabilities and real-time data synchronisation
Micro-X is an Australian nano-tech innovator developing revolutionary x-ray technology for medical and aviation applications. Their equipment represents a quantum leap in imaging capabilities, miniaturisation, and deployment flexibility. However, cutting-edge hardware requires equally sophisticated software interfaces to unlock its full potential.
The challenge facing National Digital was significant: create a user interface that matches the innovation of Micro-X's x-ray technology while functioning reliably in demanding environments. Medical imaging requires precision and clarity. Aviation security applications demand speed and accuracy. Both contexts involve users who need intuitive, responsive controls that work flawlessly whether connected to networks or operating in isolation.
Our solution leverages modern web technologies - Nuxt.js for the application framework, Apollo for GraphQL data management, TypeScript for type safety, and MQTT for IoT communication. This stack enables real-time reactivity, offline operation, and the performance necessary for professional imaging equipment.

Expected Outcome:Production-ready interface enabling Micro-X equipment deployment across medical and aviation sectors with reliable operation in any connectivity scenario
The offline operational capability distinguishes this interface from typical cloud-dependent applications. Medical facilities and aviation security checkpoints can't afford downtime due to network issues. We architected the system to function completely independently when connectivity is unavailable, synchronizing data seamlessly when connections restore.
MQTT protocol enables IoT communication between the interface and x-ray hardware. This lightweight, efficient messaging system maintains continuous bidirectional communication with minimal overhead. Commands from the interface reach the hardware instantly, while sensor data and imaging results flow back to the display in real-time. The pub/sub pattern ensures scalability if multiple devices need coordination.
The event-driven structure with webhooks provides instant reactivity. When imaging completes, adjustments occur, or status changes, the interface updates immediately without polling. This single-source architecture eliminates data inconsistencies and delivers the responsive experience professionals expect from modern medical equipment.

The Nuxt.js framework provides server-side rendering capabilities beneficial for initial load performance and potential web-based deployment scenarios. Vue's reactive system powers the dynamic interface updates, while its component architecture enabled building reusable UI elements that work consistently across medical and aviation contexts.
TypeScript adds critical type safety to a mission-critical application. Medical equipment software demands reliability - unexpected errors could impact patient care or security operations. TypeScript catches potential issues during development rather than runtime, while improving code maintainability through explicit interfaces and contracts.
The animated, interactive interface balances professional functionality with modern user experience expectations. Smooth transitions provide visual feedback confirming actions. Clear visual hierarchy guides users through imaging workflows. Responsive design ensures the interface adapts to different display sizes and orientations, accommodating various deployment scenarios from compact mobile units to full-size workstations.

Micro-X Interface: Technical Questions
How does the interface function without internet connectivity?
The offline-first architecture stores all necessary application code, user interface assets, and temporary data locally. When network connectivity is unavailable, the interface continues operating fully using local resources and MQTT communication with the x-ray hardware over local networks. User actions and imaging data are queued for synchronisation when connectivity restores. This approach ensures medical and aviation professionals can perform their work regardless of network availability, critical for remote deployments or network outages.
What is MQTT and why was it chosen for this application?
MQTT (Message Queuing Telemetry Transport) is a lightweight IoT communication protocol designed for resource-constrained devices and unreliable networks. We selected MQTT for its efficiency, reliability, and pub/sub messaging pattern. It enables instant bidirectional communication between the interface and x-ray hardware with minimal bandwidth and processing overhead. The protocol's reliability features ensure messages reach their destination even in challenging network conditions, while its lightweight nature doesn't burden the hardware or interface performance.
How does the event-driven architecture improve user experience?
Event-driven architecture with webhooks provides instant interface updates when equipment status changes, imaging completes, or errors occur. Rather than polling for updates (which introduces delays and unnecessary traffic), the system pushes changes immediately to the interface. Users see real-time feedback confirming their actions succeeded, imaging progress updates as scans proceed, and immediate alerts if issues require attention. This responsiveness is crucial for professional equipment where delays could impact patient care or security operations.
Can the interface work with multiple x-ray units simultaneously?
Yes, the architecture supports multi-device coordination through MQTT's pub/sub pattern. Each device subscribes to relevant topics while publishing its own status and data. The interface can manage multiple units, displaying aggregate status, coordinating operations, or focusing on individual devices as needed. This scalability accommodates facilities with multiple Micro-X units or centralised monitoring scenarios where administrators oversee several deployed systems.
How does TypeScript contribute to interface reliability?
TypeScript adds compile-time type checking that catches potential errors during development rather than runtime. For medical device interfaces where unexpected behaviour could have serious consequences, this safety net is invaluable. TypeScript ensures data structures match expectations, function calls use correct parameters, and integration points maintain their contracts. The explicit typing also improves code maintainability, making it easier for developers to understand and modify the codebase confidently as the interface evolves with new features.
What testing was performed to ensure interface reliability?
Comprehensive testing included unit tests for individual components and functions, integration tests validating communication between interface and hardware, end-to-end tests simulating complete imaging workflows, offline scenario testing confirming graceful operation without connectivity, and performance testing under various load conditions. We also conducted usability testing with medical and aviation professionals to ensure the interface meets real-world operational requirements. This multi-layered testing approach validates reliability appropriate for mission-critical equipment.
