摘要

近几十年来,临床胃肠病学领域出现了一种创新技术,即无线胶囊内窥镜(WCE),它是传统有线内窥镜检查的有力替代品。这种尖端应用能够通过微型化、可吞咽和生物兼容的胶囊来检查胃肠道(GI),胶囊内装有电子元件。这样就可以对生物数据进行无创测量,然后通过无线连接发送到外部接收装置。本系统综述根据 PRISMA 指南编写,重点关注从体内可吞食胶囊向外部接收器传输数据的主要技术进展。在 Scopus、Science Direct 和 IEEE Xplore 数据库中进行的全面文献检索共筛选出 142 项研究。最终有 47 项符合纳入标准并被纳入综述。研究结果强调了优化与外部接收器无线连接的有效性和安全性的创新技术。高增益、宽带、全向辐射模式和低水平的比吸收率(SAR)至关重要。尽管太空舱遥测设计相当先进,但现有的大部分研究都集中在发射装置的设计上,而不是接收装置。此外,还缺乏对现实人体模型的全面数值研究。

State of the Art on Advancements in Wireless Capsule Endoscopy Telemetry: A Systematic Approach
In the last decades an innovative technique has emerged in clinical gastroenterology as a compelling alternative to the traditional wired endoscopy, known as Wireless Capsule Endoscopy (WCE). Such cutting-edge application is able to investigate the gastrointestinal (GI) tract through a miniaturized, swallowable and biocompatible capsule, equipped with electronic components. This allows for the noninvasive measurement of biological data, that is then sent to an external receiving unit through a wireless link. This systematic review prepared according to PRISMA guidelines focuses on the main technological advances of data transmission from the in-body ingestible capsule to an external receiver. A total of 142 studies were screened from a comprehensive literature search, performed in Scopus, Science Direct, and IEEE Xplore database. A final number of 47 met the inclusion criteria and were included in the review. The results highlight innovative technologies to optimize the wireless link efficacy and safety to an external receiver. High gain, wideband, omnidirectional radiation pattern, and low levels of specific absorption rate (SAR) are of crucial importance. Despite the capsule telemetry design being rather advanced, the bulk of the existing studies focus on the transmission unit design, rather than the receiving one. Moreover, comprehensive numerical studies on realistic human body models are lacking.
