Summary
Brief summary (as posted)
Bronchoscopic diagnosis and staging of lung cancer must be gentle and quick, and requires optimal sampling precision.Electromagnetic navigation systems are promising for intraoperative guiding based on maps made of preoperative CT images. Navigation accuracy depends largely on correct alignment of preoperative images to the patient´s position in space during endoscopy. In this study, the accuracy of a new fast and automatic image-to-patient registration method during the initial phase of bronchoscopy is assessed in patients referred for lung cancer investigation.
