Abstract
The paper presents an algorithm proposed by the authors in order to obtain a theoretical model of the bronchial and used to test the virtual bronchoscopy procedure implemented in an innovative system for bronchoscopy with electromagnetically tracked and steerable biopsy forceps. The procedure is based on the Weibel theoretical model of the human tracheobronchial tree with new features added by the authors. The algorithm can be an important helping tool in the development of sophisticated algorithms for bronchoscopy applications and may be further implemented in clinical studies of navigated bronchoscopy.
