设计并验证了一种新型支气管镜跟踪原型，用于支气管镜导航。我们建立一种新型的口或鼻片支气管镜模型，直接测量患者体外支气管镜的运动信息。基于顺序蒙特卡罗（SMC）采样器融合测得的运动信息，我们利用术前和术中图像数据之间的准确和稳健的术中对准来增强外科支气管镜检查。我们验证我们的新原型幻影数据集。实验结果表明，我们提出的原型是一个很有前途的方法来导航EMT系统以外的支气管镜。
A novel bronchoscope tracking prototype was designed and validated for bronchoscopic navigation. We construct a novel mouth- or nose-piece bronchoscope model to directly measure the movement information of a bronchoscope outside of a patient’s body. Fusing the measured movement information based on sequential Monte Carlo (SMC) sampler, we exploit accurate and robust intra-operative alignment between the pre- and intra-operative image data for augmenting surgical bronchoscopy. We validate our new prototype on phantom datasets. The experimental results demonstrate that our proposed prototype is a promising approach to navigate a bronchoscope beyond EMT systems.
