【摘要】：計算機技術的快速發(fā)展使得大容量數(shù)字信息的存儲、通信和顯示均能夠實現(xiàn),這帶動了醫(yī)學數(shù)字化技術的迅猛發(fā)展,從而極大的提高了醫(yī)生的工作效率。但與此同時相關信息量也越來越大,如何才能有效地利用這些信息為醫(yī)生提供服務?于是出現(xiàn)了醫(yī)學影像存檔與通信系統(tǒng)(PACS, Picture Archiving and Communication Systems). PACS可以全面解決醫(yī)學影像獲取、顯示、儲存、傳輸及管理,使得醫(yī)學影像能夠直接從檢查設備中獲取,進而實現(xiàn)影像資料的共享和有效管理。PACS的使用可以顯著提高醫(yī)院的生產(chǎn)效率和服務質量,但由于醫(yī)學影像數(shù)據(jù)量大、數(shù)據(jù)類型復雜、規(guī)定保存時間長,這就要求PACS不僅具有海量存儲空間,而且需要具有更高的讀取數(shù)據(jù)能力。本文以計算機與醫(yī)學領域的結合為切入點,采用例證法探索了計算機技術在醫(yī)學領域的應用。 本文通過對現(xiàn)在常用的幾種存儲介質相關的技術比較與分析,結合PACS存儲架構的研究,選擇合適的存儲介質。通過對PACS存儲架構進行研究,深入探討了集中存儲和分級存儲的區(qū)別、存儲系統(tǒng)的結構層次、PACS存儲系統(tǒng)的特點,并詳細說明了在線、近線、離線的三級存儲架構以及分級存儲的優(yōu)點,而且分析了PACS建設的系統(tǒng)關鍵問題和系統(tǒng)支撐的環(huán)境�；诖颂岢隽嗽拼鎯ο到y(tǒng)的架構,通過將云存儲服務平臺應用到醫(yī)院PACS存儲系統(tǒng)建設中,即可實現(xiàn)醫(yī)院圖像的高效存儲和檢索。 在此基礎上,本文基于目前濟寧市第一人民醫(yī)院的實際需求,詳細設計了濟寧市第一人民醫(yī)院PACS實施的需求分析,并對濟寧市第一人民醫(yī)院的醫(yī)學圖像存儲方案和系統(tǒng)維護進行了嘗試性設計與應用。
[Abstract]:With the rapid development of computer technology, the storage, communication and display of large capacity digital information can be realized, which drives the rapid development of medical digital technology and greatly improves the efficiency of doctors. But at the same time, the amount of relevant information is also increasing, how can we effectively use this information to provide services for doctors? Then appeared medical image archiving and communication system PACS, Picture Archiving and Communication systems. PACS can completely solve the problem of medical image acquisition, display, storage, transmission and management, so that medical image can be obtained directly from inspection equipment. Thus, the sharing of image data and the effective management of .PACS can significantly improve the production efficiency and service quality of the hospital. However, because of the large amount of medical image data, the complexity of data types, and the long storage time, This requires PACS not only to have massive storage space, but also to have a higher ability to read data. In this paper, the application of computer technology in medical field is explored by using the method of example, which is based on the combination of computer and medical field. Based on the comparison and analysis of several kinds of storage mediums which are commonly used in this paper, and the research of PACS storage architecture, the suitable storage media is selected. Based on the research of PACS storage architecture, the difference between centralized storage and hierarchical storage is discussed in depth, and the characteristics of storage system are discussed in detail. The off-line three-level storage architecture and the advantages of hierarchical storage are analyzed, and the key problems of PACS construction and the supporting environment of the system are analyzed. Based on this, the structure of cloud storage system is put forward. By applying cloud storage service platform to the construction of hospital PACS storage system, the efficient storage and retrieval of hospital image can be realized. On this basis, based on the actual demand of the first people's Hospital of Jining, this paper designs the demand analysis of PACS implementation in the first people's Hospital of Jining in detail. The medical image storage scheme and system maintenance of the first people's Hospital of Jining were designed and applied.
