資訊科技的蓬勃發展，相繼有DICOM 3及HL7標準的公佈，所以在醫療資訊上則有兩方面的技術發展，一是PACS技術研發，偏重影像傳輸及影像處理顯示的多元化，而另一方面是文字敘述的電子病歷檔案貯存管理等，但無論由大型醫學院自行研發或科技公司推展的套裝軟體及設備而言，其經費龐大，逐步實施時間需很久，且與醫院資訊系統HIS（Hospital Information System）溝通結合的問題，還需另一階段的改善及花費。 有鑑於此，本研究即直接與資訊同仁合作研發，以醫院的資訊系統連線，下載病人基本資料，延續本科的報告列印系統，再突破影像轉檔的技術，建立核醫micro PACS。以Window NT為伺服器，行TCP/IP協定，撰寫核醫影像啟動檔，將影像、報告等用戶端，用Ethernet串成核醫科局部資訊網（LAN）；結合的資料再燒錄到CD片中，存於CD櫃伺服器，接上Hub，通上網際網路，就達到遠距離傳輸WAN的境界。所以本研發系統稱為IRIS（Integrated Report & Image System）。整合的資料可提供病歷號、姓名、檢查日期、及檢查項目等之查詢及列印。 本系統建置成功，再經逐步改善，用ROC（Receiver Operating Characteristic）分析法，來驗證其正確性後，將有以下成果：1.IRIS/HIS核醫資訊系統與醫院資訊系統密切結合，待HIS全面性影像資訊傳輸，核醫影像也可立即上線。2.發揮Filmless system的功能，醫師直接在螢幕上判讀，打報告節省膠片及照片的耗費。3.核醫專科醫師可於居家，出國時判讀編輯報告，跨院際研討及遠距離教學。4.臨床科醫師可在住院病房、診間、開刀房，由電腦查詢影像及報告，並比較前後造影的變化，更了解病程，節省借片、還片、詢問報告等工作。5.節省空間。線上查詢可見影像及報告，小小的光碟檔案櫃除當伺服器外，還可存十年的資料。6.光碟檔案櫃如核醫資料寶庫，可提供長期的追蹤、研究與統計。

　　　　　With rapid progress of Information Technology, followed by the publication of DICOM 3 and HL7 standard, the technological development of medical information has strongholds in two aspects. One is the PACS technique, based upon the image transmission, image processing and display. The other is the word descriptions of storage and management of electronic health file. However, they are both expensive, time-consuming, and difficult to integrate with HIS. (Hospital Information System). The purpose of this study is develop the Nuclear Medicine Information System (NMIS). By jointing effort with our colleague in Information System Department, we establish the micro-PACS system based on existing reporting system incorporated with imaging file conversion. Using the window NT server together with TCP/IP protocol, we integrated the nuclear medicine image files and text report files. Also we make use of ethernet network to interconnect media data in the nuclear medicine department, so as to store all of them in CD-Rom sever. The integrated data can provide clinicians easier and more informative patient data inquiry and printing. The further improvement will be linking up to internet, and achieve the goal of remote transmission. IRIS not only benefits the medical image archiving and storage, but also facilitates physician in patient report retrieval. We anticipate with the success of the system, our department will be one step ahead toward Filmless management and Telemedicine.
