| Abstract: | The micro-systems used for in vivo physical inspection have many advantages over traditional methods. In order to aid diagnosis of gastrointestinal (GI) motility disorders, a capsule is developed for GI pressure and pH inspection. Localization of the capsule in GI tract with time is a necessary condition for subsequent data analysis and medical diagnosis. It is also a common problem facing all in vivo mobile micro-systems. An approach of segment localization by utilizing some key points along GI tract is proposed. A portable ultrasonic detecting device was designed for this purpose. Experiments under conditions similar to GI tract were carried out and the results proved the effectiveness and reliability of this method and the device. |
