我们演示了使用术中显微镜安装的光学相干断层扫描系统（MMOCT）在体内进行视网膜成像。我们的光学机械设计采用了Oculus双目间接眼科显微镜（BIOM3），悬挂在徕卡眼科手术显微镜上，具有光谱域光学相干断层扫描（SD-OCT）扫描和中继光学。MMOCT可以实现视网膜结构的宽视场非接触式实时横断面成像，允许SD-OCT增强术内显微镜进行眼内可视化。我们通过实验量化了MMOCT的轴向和横向分辨率，并演示了20 Hz帧率下的眼底成像。
We demonstrate in vivo human retinal imaging using an intraoperative microscope-mounted optical coherence tomography system (MMOCT). Our optomechanical design adapts an Oculus Binocular Indirect Ophthalmo Microscope (BIOM3), suspended from a Leica ophthalmic surgical microscope, with spectral domain optical coherence tomography (SD-OCT) scanning and relay optics. The MMOCT enables wide-field noncontact real-time cross-sectional imaging of retinal structure, allowing for SD-OCT augmented intrasurgical microscopy for intraocular visualization. We experimentally quantify the axial and lateral resolution of the MMOCT and demonstrate fundus imaging at a 20 Hz frame rate.
