For exact orientation inside the tracheobronchial tree, clinicians are in urgent need of a navigation system for
bronchoscopy. Such an image guided system has the ability to show the current position of a bronchoscope
(instrument to inspect the inside of the lung) within the tracheobronchial tree. Thus orientation inside the
complex tree structure is improved. Our approach of navigated bronchoscopy considers the problem of using a
static image to navigate inside a constantly moving soft tissue. It offers a direct guidance to a preinterventionally
defined target inside the bronchial tree to save intervention time spent on searching the right path and to minimize
the duration of anesthesia. It is designed to adapt to the breathing cycle of the patient, so no further intervention
to minimize the movement of the lung has to stress the patient. We present a newly developed navigation sensor
with allows to display a virtual bronchoscopy in real time and we demonstrate an evaluation on the accuracy
within a non moving ex vivo lung phantom.
