چکیده
COND In order to construct a motion model for the endoscope camera that moves freely in the 3D tracheo-bronchial tree, a second order auto-regressive (AR) model is used. For a Kthorder auto-regressive model, the following equation applies: Flexible fiber-optic bronchoscopy is performed on patients who are fully awake or with light conscious sedation. The procedure can entail considerable discomfort if it is not handled properly. Training according to the classical apprenticeship scheme can result in prolonged surgical procedures with increased patient discomfort and a potential risk for further complications. Computer simulation, particularly the reliance on patient specific data for building anatomical models both in terms of biomechanical fidelity and photorealism has attracted extensive interests in recent years. However, accurate 2D/3D registration is important for recovering the pose of the camera in video bronchoscope sequences. Since bronchoscope images only provide localized views of the inner lumen, image-based technique cannot guarantee the convergence of the registration algorithm.
