碩士 === 國立臺灣大學 === 電機工程學研究所 === 95 === So far the capsule endoscopes used in gastrointestinal tract are carried through the body only by the peristaltic movement of the stomach and the intestines, and the capsules can not be controlled outside the body. Moreover, the stomach can be regarded as a large space comparing to the capsule endoscope. When making a diagnosis in the stomach, we may need to move the capsule endoscope back and forth around some designated place in the stomach. Lacking of the ability of moving actively, it is still difficult to use capsule endoscope to give accurate diagnosis (even treatment) in the stomach. To resolve the shortcoming given above, our research team start the study of the body-outside magnetic control theory with the guidance of Dr. Chih-Wen Liu , Professor of National Taiwan University, and Dr. Gi-Shih Lien, vice Superintendent of Wan-Fang Medical Center. At first, by applying the theory of magnetic control system, we design some experiments to satisfy the requirement of controlling outside and such that the capsule endoscope can be governed to move and rotate inside human body. This elevates the efficiency of the diagnosis (especially in the stomach). And the images of gastrointestinal tract can be taken by optical device of the capsule endoscope and be transferred to monitor by dedicated driver. Second, we also establish the user interface of the capsule endoscope system. Our goal is to build an easy and low-cost control system that can be used to control the capsule endoscope inside body more simply, quickly, and precisely. Finally, we will illustrate the experiment system and equipment, and also analyze the results of experiment to verify the theory proposed in this paper. Further, the performance and usability of whole system will be estimated, and the future work about the magnetic control system of capsule endoscope will be discussed.
