摘 要

隨著光學與資訊電子技術的發展與進步，內視鏡之於內、外科醫學已成為密不可分的一部分，科技之進步也為各式醫療儀器帶進了另一個世代。非侵入式醫療器材為現今醫學診療流行之研究趨勢，而臨床應用的領域越來越大，到最近幾年之中，甚至已成為一個專科領域。
而其中，膠囊內視鏡的興起則是為釵h有消化系統疾病的患者帶來了福音，同時也啟發了我們研究的動機，針對國內廣大的腸胃疾病市場需求對症下藥，研擬出專門取代傳統胃鏡檢驗，以減輕病患就診時的心理壓力，同時又方便操作處理、價格便宜易架設的磁浮內視系統。
在本研究中，我們嘗試以磁浮力作為我們的動力來源，在無損人體的安全係數內進行研究模擬，從驅動磁力大小規劃、選擇適當之儀器乃至設計、成型，配合影像感測元件、影像擷取卡進行內部影像的紀錄，輔以人機介面軟體的處理、分析、歸納，進而建立專屬於個人之電子病歷。而系統硬體架設方面有：可移動之電磁力平台、步進馬達、高必v之電源供應器、通用介面匯流排（GPIB， General Purpose Interface Bus）之介面儀器、個人電腦以及弁鉧膃X之操作搖桿等等；系統軟體顯像方面則是以Visual Basic來建立主要操作介面，再加上影像處理程式及影像擷取卡專屬之函數庫等等，整合軟、硬體介面而成完整的磁浮內視鏡系統。
因研究尚未符合可以進行活體研究之標準，故我們皆先以相似模擬環境來進行模擬實驗，在各式類似環境中模擬之結果皆能初步達成預設之要求，唯模型外觀部分條件仍持續改善，整體之可行性是相當可觀的。
整體而言，本實驗系統旨在成為一便利無負擔之醫療儀器，作為初期診療之用，以節省醫療資源的浪費。考量系統架設的經濟效應及方便性，取材來源皆以市面上容易獲取之器材、零件，相較於動輒百萬以上的貴重醫療儀器而言，是相當具有研究動機存在的。

Abstract

The progresses in optical engineering, computer science and electronic techniques have made the endoscopy a medical tool in both internal clinics and surgical operations. Non-invaded Medical machine is a trend of study to the medical treatment nowadays. As its applications increase exponentially, it has even become a specialized division in the clinical medicine.

However, to rise and develop the capsule endscopy not only brings good news to the patients who have disease in the digestive system but enlightens the motive of our study. To be directed against vast market of gastrointestinal disease, and to develop the convenient cheap maglev endoscopy system instead of traditional gastroscopy mitigating pressure when the patient to see a doctor.

In our study, we try to use magnetic power which can be the power resources of maglev endoscopy system. Proceeding to research and to simulate inside the human’s safety factor. We design from the driving magnetic force to instrument and even form the image system. To operate in coordination the elements of image system proceeding to take down the internal image. To handle analyzing and generalizing the Graphical User Interface which can build up personal electronics anamnesis. About computer hardware of the system includes a moving electromagnetic bench, a stepper motor, a power supply in high power, instruments of GPIB, PC and a functional joystick and so on. And computer software of the system is using Visual Basic to build up main interface which includes image processing program and image library and so on. Assembling Software and hardware to accomplish full maglev endoscopy image system.

In conclusion, our experimental system is purpose-built convenient medical instrument to make a diagnosis and give treatment at the primary stage and to avoid wasting medical resource. To think about Economic benefits and convenience of the system, so obtaining materials from business situations. Comparing with valuable medical instrument, it is a motivator to this study.
