Capsule enteroscopy, which is a wireless noninvasive approach to evaluation of the small intestine, consists of an 11 x 26-mm capsule containing a miniature video camera, batteries, illuminating light-emitting diodes, a transmitter, and an antenna. The components inside the capsule are encased by a slippery, nonbiodegradable, plastic housing, which weighs less than 4 g. Information obtained from the imager, approximately 2 frames per second, is transmitted by way of radiotelemetry to an array of sensors taped to the abdomen, which connect to a data recorder worn on a belt around the waist. The batteries are designed to last roughly 7-8 hours, providing enough energy to generate approximately 50,000 to 60,000 detailed images. The clinical review of the imagery is made available after completion of the study when images are downloaded from the data recorder to a computer with dedicated software.
胶囊内镜是一种无线无创的小肠评估方法,它由一个 11 x 26 毫米的胶囊组成,胶囊内包含一个微型摄像机、电池、照明发光二极管、发射器和天线。胶囊内的部件被一层光滑的、不可生物降解的塑料外壳包裹着,重量不到 4 克。从成像仪获得的信息,大约每秒 2 帧,通过无线电遥测传输到贴在腹部的一组传感器上,这些传感器与佩戴在腰带上的数据记录仪相连。电池的设计寿命约为 7-8 小时,提供足够的能量生成大约 50000 到 60000 张详细的图像。当研究完成后,从数据记录仪下载图像到带有专用软件的计算机上,就可以对图像进行临床评估。
