隨著電腦處理資料的能力轉移到多媒體，醫院資訊化程度才能開始不斷地深入，由傳統的全文數字資料漸漸轉變為具有文字、聲音、影像、與視訊等多媒體資料。在建構數位化醫療影像的大環境下，先期的問題是新的醫院資訊系統必須具備解決大量數位化醫療影像相關儲存及通訊傳輸等能力。近來寬頻網路技術與電腦專業晶片技術的出現，前端工作站的執行效能與儲存媒體容量都較已往強化很多，並且繼續在寬頻網路的瓶頸突破，使得建構分散多工的數位化醫療環境變成一確實可行的方案。 醫療環境從專業儀器所產生的影像、到影像儲存、到多媒體資訊系統的管理、到影像送至個個使用地點，資訊系統（HIS,RIS,PACS）間出現共同語言的問題。三軍總醫院藉由國防醫學中心整體資訊系統的規劃，將此世界潮流的醫療影像擷取及傳輸系統（PACS）納入計畫之中，並於民國87年7月底完成第一階段建置計畫。本計畫的主要目標是奠定三軍總醫院未來全院性醫療影像系統發展的基礎， 同時全系統採用國際醫療影像標準（DICOM），除醫療影像儀器所擷取的影像符合DICOM標準外，資料庫伺服器與影像儲存資料庫都依DICOM標準建置。 本文主要討論國防醫學中心計畫屬於醫療影像之主要應用，第一階段計畫著眼在面臨新舊環境整合的思考，特別心得在結束以往各自獨立的影像系統，轉而走向標準，統（DICOM）， 除醫療影像儀器所擷取的影像符合DICOM標準外，資料庫伺服器與影像儲存資料庫都依DICOM 標準建置。 本文主要討論國防醫學中心計畫屬於醫療影像之主要應用，第一階段計畫著眼在面臨新舊環境整合的思考，特別心得在結束以往各自獨立的影像系統，轉而走向標準，統籌走向PACS影像系統，期望對未來整個醫療影像系統的發展奠定基礎，長遠看來是好的開始。

　　　　　With the innovation of computer processing ability, the level of hospital computerization can be improved. In addition to the traditional textural and numeric data type, a hospital information system can also simultaneously process medical images, document images, video, and voice data types. To construct a digital medical image information system, the first encounter problem is that the hospital information system must have adequate ability to solve the storage and communication problems for huge amount of digital medical images. Recently, technologies for broadband networks and computer chips make the clients' workstation to not only have excellent processing and storage abilities, but also keep exploring the breakthrough of the bottleneck about broadband networks. All of those make the construction of a distributed, digital medical image environment not to be a dream anymore. A digital medical image system consists of acquisition of medical images from each medical device, transformation to image archiving system, management of multimedia database system, and image display on every view workstations. The medical image environment is so complicated that a common interface is definitely necessary to integrate all information systems (such as HIS, RIS, and PACS). With the responsibility of Tri-service General Hospital (TSGH) to construct a totally integrated information system for new National Defense Medical Center, we tried to integrate the picture archiving and communication system (PACS) within the whole project and finished the implementation of stage one in July 1998. The major goal of this project was to consolidate the foundation of the medical image information system. Simultaneously, we insisted on following international image standard DICOM throughout the entire PACS system. In addition to the image format being followed DICOM standard, the data base server and the image archiving storage system were constructed following DICOM standard, too. In this paper, the major applications about digital medical images system in NDMC will be discussed. The first stage of implementation emphasized on the integration of new digital image environment and the existing data information environments, especially on the end of each independent image systems and going to a standard PACS system. We hope this exploit can be a good experience for the future medical image system. It is good beginning from the long-term point, we believed.
