我们报告了一种新的光学相干断层扫描（OCT）球囊成像导管的光学设计。该设计涉及一个微型复合梯度折射率（GRIN）棒透镜，它包括一个光纤模场缩减器和中继棒透镜，以实现预期的高横向分辨率在所需的大工作距离。复合透镜设计显著简化了OCT导管的工程过程，并且能够实现诸如人类食道的大管腔器官的3D全周向横截面成像。设计的OCT导管的开发和证明实时在体内猪食管成像在3-D螺旋的方式。(C)2008年，由光学仪器工程师协会（Society of Photo-Optical Instrumentation Engineers）主办。[DOI 10.1117/1.3037340]
We report on a new optics design for an optical coherence tomography (OCT) balloon imaging catheter. The design involves a miniature compound gradient-index (GRIN) rod lens, which consists of a fiber optic mode-field reducer and relay rod lenses to achieve predictable high lateral resolution at a desired large working distance. The compound lens design significantly simplifies the engineering process for an OCT catheter and enables 3-D full circumferential cross sectional imaging of large luminal organs such as human esophagus. An as-designed OCT catheter is developed and demonstrated for real-time in vivo swine esophagus imaging in a 3-D spiral fashion. (C) 2008 Society of Photo-Optical Instrumentation Engineers.
