To compare off-the-shelf digital imaging equipment with a standard single lens reflex 35-mm endoscopic camera in a busy pediatric ears, nose, and throat setting.
Two digital cameras with an endoscope adapter and a step-down ring were evaluated to obtain optimal settings for digital endoscopic photography. The equipment was used in various clinical and surgical settings to include otoscopy, sinonasal endoscopy, laryngoscopy, and bronchoscopy. The overall quality, color, brightness, and diagnostic quality of the endoscopic digital photographs were compared with those of the single-lens reflex 35-mm flash-generated photographs by experienced endoscopists. Cost analysis and ease of use were also compared. Subjects Initial digital endoscopic settings were formulated from cadaveric tests. These settings were then studied in multiple patients during endoscopy.
Endoscopic digital photography resulted in high-quality images in all settings. Digital images were comparable to 35-mm images. The digital system was easier to use and less expensive than the 35-mm system.
We introduce a simple, inexpensive, and easily available endoscopic digital photography system. Digital photography offers numerous advantages over analog photography in a clinical practice. Digital imaging and archiving is more durable and easier to incorporate into patient records and clinical presentations. As the demand for high-quality digital imaging increases, easy-to-use inexpensive digital endoscopic photography will soon replace 35-mm camera technology.
在繁忙的儿科耳鼻喉科环境中，将现成的数字成像设备与标准的35毫米单镜头反光内镜相机进行比较。
对两台配有内镜适配器和转接环的数码相机进行评估，以获得数字内镜摄影的最佳设置。该设备用于各种临床和手术场景，包括耳镜检查、鼻窦内镜检查、喉镜检查和支气管镜检查。经验丰富的内镜医师将内镜数字照片的整体质量、颜色、亮度和诊断质量与单镜头反光35毫米闪光拍摄的照片进行比较。还比较了成本分析和易用性。对象初始数字内镜设置由尸体试验制定。然后在多名患者的内镜检查过程中对这些设置进行研究。
内镜数字摄影在所有场景下均能产生高质量图像。数字图像与35毫米图像相当。数字系统比35毫米系统更易于使用且成本更低。
我们介绍了一种简单、廉价且易于获得的内镜数字摄影系统。在临床实践中，数字摄影比模拟摄影具有众多优势。数字成像和存档更持久，更容易纳入患者记录和临床报告中。随着对高质量数字成像需求的增加，易于使用的廉价数字内镜摄影很快将取代35毫米相机技术。
