Short-wave infrared (SWIR/NIR-II) fluorescence imaging has received increased attention for use in fluorescence-guided surgery (FGS) due to the potential for higher resolution imaging of subsurface structures and reduced autofluorescence compared to conventional NIR-I imaging. As with any fluorescence imaging modality introduced in the operating room, an appropriate accounting of contaminating background signal from other light sources in the operating room is an important step. Herein, we report the background signals in the SWIR and NIR-I emitted from commonly-used equipment in the OR, such as ambient and operating lights, LCD screens and surgical guidance systems. These results can guide implementation of protocols to reduce background signal.
由于与传统近红外I成像相比，短波红外（SWIR/NIR-II）荧光成像具有对皮下结构进行更高分辨率成像的潜力以及更低的自发荧光，因此在荧光引导手术（FGS）中的应用受到了越来越多的关注。与手术室中引入的任何荧光成像方式一样，对手术室中其他光源产生的污染背景信号进行适当的评估是重要的一步。在此，我们报告了手术室中常用设备发出的短波红外和近红外I背景信号，如环境光和手术灯、液晶显示屏及手术导航系统。这些结果可为减少背景信号的方案实施提供指导。
