Lung Digital Twin
Inside every lung is a map no one can fully see – a thousand branching airways, vessels threaded between them, and somewhere in the maze, a nodule the width of a grain of rice. From one lung CT scan, LTTS builds an AI digital twin that sees its anatomy, diagnoses what matters, and navigates the route in, so the device sent to find it no longer goes in blind.
The LTTS Lung Digital Twin
The Device Goes in Almost Blind
A bronchoscope threads a maze of airways toward a target millimetres wide, with limited spatial context and vessels it cannot see. The intelligence that would let it navigate with certainty is the hardest part of the device to build, and the slowest to clear.
Navigating blind
Lung navigation devices enter a branching maze of airways with little forward view of the optimal path or the vessels nearby
The data problem
Medical AI is starved of large, diverse, annotated datasets – and manual annotation is slow, costly, and hard to scale
Proving the AI
Regulators and clinicians now expect device makers to show how an AI model reached its conclusion, not just the output
Build vs. buy
Building organ intelligence in-house takes years and deep specialist teams, delaying the device's route to market
The result: the layer that would set your device apart is the one your team can least afford to build from scratch.
Feature Highlights
- Auto-segments airways, vessels, and the five lobes into a 3D reconstruction with an anatomical reference baseline

- Detects and localizes tumors, fibrosis, emphysema, and obstruction
- Measurement and quantification (airway diameter, volumetrics)
- Risk assessment
- Explainable AI
- Virtual bronchoscopy navigation
- Optimal scope path
- Vessel-proximity mapping
- Branch-by-branch guidance
- Pre-procedural planning
- Airflow and tissue-mechanics simulation via CFD
- Disease-progression, treatment-response and outcome forecasting
- What-if scenarios run virtually
- Multi-planar and 3D rendering
- Quantitative measurement
- Tumor-growth progression analysis and monitoring
Track Record & Proof
Built on LTTS Engineering Intelligence, the lung twin was engineered with practicing pulmonologists and surgeons, grounding the model in real clinical workflows rather than a research prototype. Built today, extensible tomorrow. The structural, diagnostic, and procedural twins are built and demonstrable for the lung. A behavioral twin is part of the roadmap, with the same framework is designed to extend across organs.
Proof points
- Patented navigation method — “Method and system for guiding navigation of an imaging tool”
- 90%+ AI-automated segmentation, with no manual annotation
- Built with practicing pulmonologists and surgeons
- Trained on diverse, multi-source clinical data
- Reusable framework: lung today; liver, heart, brain and eye on the roadmap

Outcome
Navigate with a plan
- Faster to market: Up to 50% faster to market than building the organ-intelligence layer in-house - you start from a working, patented twin, not a blank sheet.
- Lower data burden: 90%+ automated segmentation cuts the dependence on massive, costly annotated datasets.
- Differentiation: Navigation and explainability become the layer that sets your device apart.
- Regulatory readiness: Explainable AI supplies the transparency case regulators and clinicians now expect.
- Scale across organs: One reusable framework: lung today; liver, heart, brain and eye next.
- Protected Solution: The navigation method at the core of the twin is patented.
The Intelligence Inside Your Next Device
One scan. One living twin. Structural, diagnostic and procedural today - behavioral on the roadmap, and a framework that scales across organs.

The LTTS Lung Digital Twin
A bronchoscope threading a thousand airways toward a nodule the size of a rice grain — with vessels it can't see. That's the hardest problem in medical AI. Here's how we solved it.
