摘　　要：目的解决由于影像存档和传输系统(PACS)服务器处理性能滞后带来的系统性能下降,影像传输速度过慢的问题。方法在不升级整个PACS的前提下,在影像工作站EA4.0服务器设置新的网络节点,将图像先上传到新添加的EA4.0服务器上,再由EA4.0服务器转存到PACS服务器中。结果通过很长一段时间的后续观察,极大地提高了检查工作站向PACS服务器传输影像资料的速度,解决了影像传输速度过慢的问题,减少了诊断医生从PACS服务器调阅图像时的等待时间。结论充分发挥医院现有设备的潜能,解决了影像传输速度过慢问题,使PACS充分发挥了其在影像科室的应用价值。Objective To solve the bottleneck problems on decreasing system performance and low speedof image transmission due to the processing performance lag of Picture Archiving and CommunicationSystem (PACS) server. Methods In the premise of no upgrading the entire PACS system, a new networknode was set up on the image workstation. The images were uploaded to the newly added EA4.0 server,and then transferred to the PACS server by EA4.0 server. Results By follow-up observations for along period of time, the speed of image transmission from inspection workstation to PACS server wasgreatly improved. The bottleneck problem on low speed of image transmission was solved. The time ofthe diagnostician waiting for images from PACS server was saved. Conclusion It made full use of thepotential of the hospital’s existing equipment. And the problem of slow image transmission speed wassolved so that PACS could fully play its application value in the imaging department.
