Wireless capsule endoscopy (WCE) is an ingestible electronic diagnostic device capable of working wirelessly, without all the limitations of traditional wired diagnosing tools, such as cable discomfort and the inability to examine highly convoluted sections of the small intestine. However, this technique is still encountering a lot of practical challenges and requires further improvements. This paper is to propose the methodology of investigating the performance of a WCE system by studying its electromagnetic (EM) wave propagation through the human body. Based on this investigation, the capsule’s positioning information can be obtained. The WCE transmission channel model is constructed to evaluate signal attenuations and to determine capsule position. The detail of this proposed research methodology is presented in this paper.
