We currently present a design concept for a photoacoustic imaging endoscope as well as some preliminary experimental results. The device is based on the generation of acoustic waves in tissue by short laser pulses and the sensing of these waves with a thin, optical Fabry-Pérot etalon. The entire device is designed to be mounted on the tip of a needle to deliver high-resolution photoacoustic imaging for minimally-invasive clinical applications such as diagnosing kidney disease and guiding laparoscopic surgery.
我们目前展示了一种光声成像内窥镜的设计概念以及一些初步实验结果。该设备基于短激光脉冲在组织中产生声波，并利用一个薄的光学法布里-珀罗干涉仪来检测这些声波。整个设备设计安装在针的尖端，以便为诸如诊断肾脏疾病和指导腹腔镜手术等微创临床应用提供高分辨率光声成像。
