摘要：
A method and system for automatic landmark registration and registrationusing trajectory information and shape sensing during an endoscopic procedure,such as bronchoscopy, are described herein. A segmentation centerline ofairwaysof a lung may be generated based on a pre-operative computed tomography (CT)image of the lung. Landmarks may be automatically detected on the segmentationcenterline corresponding to bifurcations in the airways of the lung. Alocation datapoint cloud of locations of a catheter through the airways of the lung duringnavigation may be generated. A bounding volume of the airways of the lung maybegenerated and a bounding volume centerline may be detected. Landmarks may bedetected on the bounding volume centerline for the same bifurcations. Then,the twosets of landmarks may be mapped as part of registration. The trajectoryinformation with shape sensing may be used to provide non-rigid or fineregistration.
