Laryngeal lesions were observed with the Olympus ENF-200 rhinolarynx electronic videoendoscope attached to the Olympus EVIS-200 system, an electronic videoendoscope system of Olympus Optical Co, Ltd. The electronic videoendoscope differs from conventional flexible fiberscopes in having a small light-sensitive charge-coupled device (CCD) chip built into the tip of the endoscope portion. This model has a small CCD chip in its 5-mm-outer diameter tip, and can be introduced into the laryngeal cavity by inserting it through the nasal passages. Dynamic color images obtained by this system were very clear and provided excellent resolution. This electronic videoendoscope system could also be connected to the Olympus EVIP-230 digital image processor, which was compatible with this system. Structure enhancement and color enhancement were performed by processing images. In this paper, the ordinary images and the processed images are described and discussed from the standpoint of diagnostic usefulness.
使用连接到奥林巴斯EVIS - 200系统的奥林巴斯ENF - 200型鼻咽喉电子视频内窥镜观察喉部病变，该系统是奥林巴斯光学有限公司的电子视频内窥镜系统。电子视频内窥镜与传统的柔性纤维内窥镜不同，其在内窥镜部分的尖端内置有一个小型的光敏电荷耦合器件（CCD）芯片。该型号在其外径5毫米的尖端有一个小型CCD芯片，可通过鼻腔插入引入喉腔。该系统获得的动态彩色图像非常清晰，分辨率极佳。该电子视频内窥镜系统还可连接到与该系统兼容的奥林巴斯EVIP - 230数字图像处理器。通过处理图像进行结构增强和色彩增强。在本文中，从诊断实用性的角度对普通图像和处理后的图像进行了描述和讨论。
