【摘要】 目的　解决我院图像存储与传输系统 (picturearchivingandcommunicationsystem ,PACS)大规模应用、大流量数据传输的网络需求 ,以及随之出现的负载均衡、潜在网络风暴的问题。方法　网络主交换机采用英特尔 (Intel) 4 80T 10 0 0M交换机 ,各大楼间采用 10 0 0M光纤接入 ,10 0M光纤连接到每个信息点 ;原有网络保持物理独立 ,采用新型的第 3或第 4层交换设备 ,减轻该路网络的流量负担 ,解决负载均衡 ;每个具有医学数字成像及通讯 (digitalimagingandcommunicationinmedicine ,DICOM)标准的设备均铺设超 5类屏蔽双绞线 ;增设IntelNetStructure 15 2 0CacheAppliance缓存器解决网络风暴。结果　通过本设计建立起了 1套科学完善的院内网络体系 ,适应和满足了目前PACS的高需求 ,并为将来向 10 0 0M应用升级提供了良好的硬件条件 ,为在院内实现图像、信息、病人资料等方面的共享与传输提供了保障 ,为医院科学化、规范化管理奠定了基础。结论　建立PACS影像系统必先考虑良好的发展规划 ,硬件设施是PACS及所有医院信息管理的基础平台 ,因此应从多方位全面考虑网络状况和将来发展 ,搭建好良好的硬件平台是必要条件 ,而且可以利用线路共享性为其他的网络信息管理系统提供服务及数据共享更多还原

【Abstract】 Objective To meet the networking requirement of the heave data flow, load balance, and potential networking storm during expanding the application of PACS. Methods Intel NetStructure 480T Giga Switch was used as main switch and connected to each building by optical channel at 1 Giga speed to archive 100 MB/s to each port. At the same time, the in dependence of the original networking construction was physically kept. The layer 3 and 4 switchers was used as load balance to reduce the heavy load of the networking, and all the cabling for PACS used the super CAT5 along with the Intel NetStructure 1520 to prepare for the potential networking storm. Results An advanced intranet was set up to fully meet the high standard requirement of PACS. The good foundation for upgrading the whole networking system to 1 Giga application was built for realized share and transmission of image, information, and patient data within the hospital. The base was established for the standardized manangement of the hospital. Conclusion Good planning is the 1st step in setting up PACS and the equipments are the platform to run PACS and all kinds of HIS. The networking construction is the foundation of e hospitals.更多还原
