眼内组织的实时术中B扫描光学相干断层扫描（OCT）可视化是视网膜手术期间所需的眼科特征。将一种新型眼内25号B模式前向成像OCT探头与36号针组合成原型仪器。针尖本身的成像和盐水注射到明胶体模的影响进行。组合B扫描前向成像OCT针原型能够实时成像盐水注入明胶体模。未来的进一步小型化可能使该仪器成为玻璃体视网膜手术的连续实时成像和手术工具。
Real-time intraoperative B-scan optical coherence tomography (OCT) visualization of intraocular tissues is a desired ophthalmic feature during retinal procedures. A novel intraocular 25-gauge B-mode forward-imaging OCT probe was combined with a 36-gauge needle into a prototype instrument. Imaging of the needle tip itself and the effects of saline injection into a gelatin phantom were performed. A combined B-scan forward-imaging OCT-needle prototype was capable of real-time-imaging of saline injection into a gelatin phantom. Additional future miniaturization may permit this instrument to be an adjunctive realtime imaging and procedure tool for vitreoretinal surgery.
