Abstract

Recent developments in capsule endoscopy have highlighted the need for accurate techniques to estimate the location of a capsule endoscope. A high accuracy localization of the order of millimeters is required for endoscopic applications. Location estimation of a capsule endoscope in the gastrointestinal (GI) tract is a challenging problem, as radio frequency signals encounter a high loss and highly dynamic channel propagation environment. In this paper, the characteristics of radio frequency signal absorption inside the human body are investigated with the aim of developing an accurate propagation model. Furthermore, the possibility of using a radar system for capsule localization is investigated and compared to its operation in the 2.4G Hz ISM band.
