【摘要】 PACS是上世纪80年代以来随着数字成像技术、计算机技术和网络技术的进步而迅速发展起来的,它是将各种医学影像设备连接起来,并将归档的数据和图像及时发送到工作站,从而全面解决医学图像的获取、显示、存贮、传送和管理的分布式系统。通常一个PACS由下列部分组成:图像归档服务器、图像获取设备、诊断工作站、图像输出设备等。这里我们讨论的是一种基于浏览器/服务器(B/S)模式的PACS,它借助普通浏览器与服务器连接,其客户端仅保留表示逻辑,而将业务逻辑和事务逻辑都放在服务器端,不仅大大提高了系统的安全性、稳定性,而且提高了系统的可维护性,便于扩充。 本论文所讨论的系统基于Dicom(Digital Imaging and Communications in Medicine)3.0标准,以Java为编程语言、以J2EE为开发平台,运用了EJB、Servlet、JSP等多项编程技术。论文详细论述了系统的几个重要功能,这些功能的添加对PACS有重要意义。本文主要内容及创新: 1.PACS服务器群集的设计与实现,增强了PACS的稳定性,实现了高可用性网络。 2.采用Java Applet开发了PACS Viewer,使远程医疗成为可能,扩充了使用PACS的范围。 3.采用Servlet实现了病人检查的备份与恢复,做到了随时备份,随时恢复,增强了系统的可用性和抗风险能力,并有利于病例的交流。 综上所述,本论文所论述的工作增强了B/S模式的PACS的稳定性,安全性,扩充了其使用范围。更多还原

【Abstract】 PACS is a distributed system developed quickly with the development of digital imaging technology, computer technology, and network technology since 1980s. In PACS, the different medical imaging facilities are connected, and archived data and images are sent to workstations in time. So as to totally solve the capture, display, preservation, transfer and administration of medical images. PACS is usually comprised of image archiving server, image capturing facilities, diagnosis workstations and image-output facilities. Here, PACS based on B/S (Browser/Server) architecture is discussed, web browser is connected with server. Business logic and web logic are run in server while client workstations take only charge of display logic. Therefore, not only are the security and stability of the system improved, but also is the availability of the system improved and is PACS convenient to update.DICOM(Digital Imaging and Communications in Medicine) standard is obeyed in the system, and JAVA is adopted as its programming language, and the system is based on J2EE platform. EJB, Servlet, JSP and other programming techniques are adopted. Some key functions are discussed in the thesis in detail, and they have great meanings to PACS. This thesis focuses on:1. PACS Cluster Service is designed and realized. The stability is improved, and the network became high-available.2. PACS Viewer based on Java Applet is developed, telemedical treatment became possible, and the available range of PACS is enlarged.3. Backup and recovery of patients’ studies are realized and can be archived whenever we need. Availability and the ability of the system to resist risk is improved, and it’s in favor of the communication of patient’s cases.As is shown above, applying above mentioned our works to PACS, the stability and safety is improved, the available range of the system is enlarged.更多还原
