【摘要】 光学成像技术具备高分辨、多尺度、多维度、易集成以及低辐射等优势，在生物医学领域发挥重要的作用。在内窥镜领域，如何进行内窥图像信息的获取、处理及可视化是光学成像技术要解决的核心问题，在医学临床中获取内窥镜所观察部位的跨尺度图像有利于医师对于患者病情的诊断以及提升术中操作的精确程度。本文从跨尺度光学成像技术在内窥镜领域的应用入手，重点阐述了目前内窥镜临床中用于获取跨尺度图像的光学系统类型，包括跨尺度变焦光学系统、光纤扫描成像系统、多通道成像系统等，说明了这些跨尺度光学内窥镜系统如何获取跨尺度图像，并对跨尺度光学成像在内窥镜领域的未来发展做了展望。更多还原

【Abstract】 Due to the advantages of high resolution, multi-scale, multi-dimension, low radiation and easy to integrate, optical imaging technology plays an important role in biomedical field. In the field of endoscopy,how to obtain, process and visualize the endoscopic image information is the core of the problem what optical imaging technology need to solve. The obtaining of trans-scale endoscopic image of patients in the medical clinical is more advantageous to the surgeon for the diagnosis of patients and can improve in accuracy of the operation. The review starts with the application of trans-scale optical imaging technology in the field of endoscopy, focusing on the different optical systems to obtain trans-scale images in clinical endoscopy, including trans-scale optical zoom system, multi-channel imaging system, fiber-scanning imaging system, and expounds its progress and future trends.更多还原
