Free Virtual Bronchoscopy Simulator

BronchSim — learn bronchial anatomy and practice airway navigation in an interactive 3D airway.

BronchSim is a free virtual bronchoscopy simulator for learning bronchial anatomy and practicing airway navigation. Drive a bronchoscope through an interactive 3D airway reconstructed from a real CT scan — down the trachea, past the carina, and into the lobar and segmental bronchi of both lungs.

Built as a bronchoscopy training and education tool, it lets medical students, residents, and pulmonary and critical care fellows rehearse tracheobronchial anatomy at their own pace, with nothing to install — it runs in any modern web browser. Explore mode flies freely through the airway; Quiz mode tests segmental anatomy by asking you to name and identify each bronchus; Challenge mode adds timed navigation tasks and foreign-body aspiration cases for bronchoscopy practice under pressure.

Whether you are preparing for your first bronchoscopy, teaching airway anatomy, or reviewing the bronchial tree, this virtual bronchoscopy simulator makes segmental anatomy easier to learn and remember. Free and open for education.
