摘要
隨著科技的日新月異，尤其是光學感測元件和無線電子技術的進步，膠囊內視鏡已廣泛應用於小腸疾病的檢查。僅管如此，目前市面上的膠囊內視鏡仍受到許多的限制，例如:不具有控制性，無法做定點或是更深入的檢查，只能被動地跟著小腸蠕動前進，且僅適用於小腸疾病的檢查，並不適合胃部。 有鑒於此，本研究團隊已研製出一套遠端的磁控系統應用於胃部膠囊內視鏡，此系統成功整合永久磁鐵、光學影像模組和電源與信號傳輸線，經由簡單、方便與低成本的磁場導引控制，醫生可以在消化道中檢查各個部位，特別是胃部；此外透過後端的影像處理，能有效提升影像擷取卡所擷取到的影像品質，有助於醫生對於病情的診斷。 最後依據磁力控制與影像處理的試驗，其結果顯示膠囊內視鏡於人體胃部中，不論是運動控制或影像觀測，皆具有高度的潛力與可行性。

With the advent of modern techniques, especially the advance in optical sensors and wireless electronic techniques, capsule endoscopes have been commercially available for the examination of small intestine disorders. However, the present devices still suffer from several limitations: the current capsules propagate passively by exploiting peristalsis through the digestive track and are, consequently, unable to be controlled to localize at an area of interest for a prolonged diagnosis. In addition, the usage of current capsules is restricted primarily to the small intestine and is inappropriate for the stomach. To overcome these limitations, our research team has designed and fabricated a remote magnetic control system targeted for capsule endoscopic operations in the stomach, which contains permanent magnets, optical image modules and power as well as signal transmission line. Utilizing the proposed magnetic guidance control that is convenient, highly efficient, and low in cost, doctors can investigate every portion of the irregular area in the gastrointestinal tract, especially in the stomach. Besides, through image post-processing techniques, the quality of consecutive images captured by image capture boards can be greatly improved, which offers doctors a reliable way in disease diagnosis. Finally, based on experiments of magnetic control and image processing, experimental results have demonstrated great potentials and feasibilities of visualizing capability and actively controlling the motion of the capsule endoscope in the stomach.
