Endoscopic imaging using optical coherence tomography (OCT) has been demonstrated as clinically useful in the assessment of human airways. These airways have a complex 3D structure, bending, tapering and bifurcating. Previously published 3D OCT reconstructions have not accounted for changes in the orientation and trajectory of the endoscopic probe as it moves through the airway during imaging. We propose a novel endoscopic setup incorporating a magnetic tracking system that accounts for these changes, yielding reconstructions that reveal the true 3D nature of the imaged anatomy. We characterize the accuracy of the system, and present the first published magnetic tracker-assisted endoscopic OCT reconstructions using a phantom airway.
使用光学相干断层扫描（OCT）的内镜成像已被证明在评估人体气道方面具有临床实用性。这些气道具有复杂的三维结构，会弯曲、变细和分叉。先前发表的三维OCT重建未考虑在内镜探头在成像过程中穿过气道时其方向和轨迹的变化。我们提出了一种结合磁跟踪系统的新型内镜设置，该系统考虑了这些变化，从而产生能够揭示成像解剖结构真实三维性质的重建图像。我们对该系统的准确性进行了表征，并展示了使用模拟气道进行的首次发表的磁跟踪辅助内镜OCT重建。
