PICO Framework
| P — Population | Bronchoscopy procedures (simulation-based setting with 18 bronchoscopy videos) |
| I — Intervention | AIBAN (AI Bronchial detection and Airway Navigation system) using YOLOv8-based detection for real-time landmark identification |
| C — Comparator | No explicit comparator - validation against ground truth anatomical locations |

Bottom Line
This proof-of-concept study presents AIBAN, an AI-powered navigation system for bronchoscopy that achieved 91% accuracy in identifying bronchoscope location during simulation testing. While the technical approach appears promising, the evidence is preliminary with significant limitations including a very small validation dataset (3 videos), absence of clinical testing, and lack of statistical rigor. The system's potential for improving bronchoscopy precision and training is intriguing, but substantial additional validation including clinical trials, comparison with existing methods, and safety assessment would be required before clinical implementation. Australian clinicians should view this as early-stage technology development rather than ready-for-practice innovation. The work establishes a foundation for future research but does not yet provide sufficient evidence to change current bronchoscopy practice or training protocols.

Abstract
BACKGROUND: Accurate navigation within the lungs is critical for bronchoscopy procedures but remains challenging due to the complex airway anatomy. Artificial intelligence (AI) integrating real-time landmark detection and navigation guidance may enhance precision and safety. METHODS: We developed an AI Bronchial detection and Airway Navigation system (AIBAN) for bronchoscopy, combining airway lumen detection, anatomic localization, and navigation guidance. A YOLOv8-based detection module was used to identify 34 airway landmarks in real time. Next, an airway-level localization module estimated the bronchoscope's position using a hierarchical anatomic graph, identifying the deepest branch compatible with all coherent detections in each frame. A navigation module then recommended the next airway to follow along predefined anatomic paths, providing directional cues to perform a complete and systematic bronchoscopy. RESULTS: AIBAN was developed on a data set of 18 bronchoscopy videos, using 15 for training and 3 for validation. In validation, the framework correctly identified the bronchoscope's location in 91.1% of the frames. In addition, 92.6% of predictions were within one airway branch of the true location, and 94.5% were within 2 branches. The navigation guidance performance was also promising, with the system following the correct anatomic pathway in 96.2% of test videos, demonstrating reliable guidance through the lungs. CONCLUSION: AIBAN enables accurate airway detection, localization, and navigation guidance in a simulation-based setting. It can provide reliable guidance along predefined paths and precise spatial positioning and is a promising tool for medical training and has potential for future clinical implementation.
