We present a novel approach to motion compensation for bronchoscope navigation where the bronchoscope trajectory is modeled using a spline curve. Initial position and orientation measurements from electromagnetic tracking are refined using the distance of the trajectory from airways segmented in preoperative CT data, and similarity between real and virtual bronchoscopic images. We present an evaluation on a dynamic motion phantom and on a moving ex-vivo porcine lung. Ground truth data is provided by human experts.
