Abstract

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.
