In flexible endoscopy techniques, such as bronchoscopy, there is often a challenge visualizing the path from start to target based on preoperative data and accessing these during the procedure.
Lung cancer is the major cause of cancer-related death. Published success rates vary depending on techniques and experience of the pulmonologists. Early detection and precise staging have the highest impact on survival.
To solve the challenge of orientation, navigation systems help the pulmonologist to guide the instrument and the biopsy tool through the very complicated and distant airways with GPS-like tracked instruments displayed in 3D maps.
For the last 20 years there have been numerous publications on navigated bronchoscopy, including studies that demonstrate various registration techniques of 3D data to the patient, e.g., by the use of airway centerlines, electromagnetically tracked bronchoscope or biopsy tools and virtual bronchoscopy (VB) or combinations.
