Abstract
A simple common path optical coherence tomography using a fibre optic bundle as a probe is demonstrated experimentally. The mechanical lateral scans are accomplished outside the specimen, proximal entrance of the fibre bundle, which eliminated the need for moving parts in the distal end of the probe. This feature allows the probe to be made submillimetre in size and easily integrated into surgical tools for intraoperative imaging. The axial and lateral resolutions of the system, and preliminary images of phantom samples, are reported.
摘要
实验展示了一种使用光纤束作为探头的简单共光路光学相干断层扫描技术。机械横向扫描在标本外部、光纤束近端入口处完成，这消除了探头远端需要移动部件的需求。这一特性使得探头尺寸可制成亚毫米级，并易于集成到手术工具中用于术中成像。报告了该系统的轴向和横向分辨率以及模拟样品的初步图像。
