Use of augmented fluoroscopic imaging during diagnostic bronchoscopy.

The single pulmonary nodule evaluation is a complex problem. In particular, attempts to biopsy peripheral nodules with bronchoscopy have been hampered by difficulty navigating to the correct airway and then confirming the instruments' proximity to the nodule. Virtual systems in use do not provide real-time feedback of a live image of the nodule in question. Fluoroscopy has traditionally offered limited assistance as often the nodule is not visible and provides no information on airways/pathways to the nodule. We describe the use of LungVision augmented fluoroscopy to aid in real-time navigation assistance to peripheral lung nodules.
