摘要： A global registration system and method identifies bronchoscope position without the need for significant bronchoscope maneuvers, technician intervention, or electromagnetic sensors. Virtual bronchoscopy (VB) renderings of a 3D airway tree are obtained including VB views of branch positions within the airway tree. At least one real bronchoscopic (RB) video frame is received from a bronchoscope inserted into the airway tree. An algorithm according to the invention is executed on a computer to identify the several most likely branch positions having a VB view closest to the received RB view, and the 3D position of the bronchoscope within the airway tree is determined in accordance with the branch position identified in the VB view. The preferred embodiment involves a fast local registration search over all the branches in a global airway-bifurcation search space, with the weighted normalized sum of squares distance metric used for finding the best match.

摘要： Two system-level bronchoscopy guidance solutions are presented. The first incorporates a global -registration algorithm to provide the physician with updated navigational and guidance information during bronchoscopy. The system can handle general navigation to a region of interest (ROI), as well as adverse events, and it requires minimal commands so that it can be directly controlled by the physician. The second solution visualizes the global picture of all the bifurcations and their relative orientations in advance and suggests the maneuvers needed by the bronchoscope to approach the ROI. Guided bronchoscopy results using human airway-tree phantoms demonstrate the potential of the two solutions.
摘要翻译：提出了两个系统级支气管镜指导解决方案。第一个结合了全局注册算法，为医生在支气管镜检查期间提供更新的导航和指导信息。该系统可以处理一般导航到感兴趣的区域（ROI）以及不良事件，并且它需要最少的命令，以便它可以由医生直接控制。第二个解决方案可以提前了解所有分岔及其相对方向的全局图，并建议支气管镜需要进行ROI的操作。引导支气管镜检查结果使用人类气道树模型显示了两种解决方案的潜力。
