Abstract
Abstract. The capsule endoscope, as one of important equipment in screening the entire spectrum of digestive tract disease diagnosis, has largely compensated for the limited of vision field and poor patient experience of wired endoscopes. In order to better develop the clinical application of capsule endoscope and assist doctors in the diagnosis and treatment of gastrointestinal diseases, there is an urgent need to solve a key scientific problem, that is obtaining the position information of capsule endoscope in the body. This article reviews the research evolution of the capsule endoscope based on magnetic localization through the last 10 years and describes notable problem, as well as technological challenges to overcome. Besides that, the article also presents the future development in capsule endoscopy localization technology based on magnetic sensors, for further developing capsule endoscopy localization and surgical navigation.
