Application of Stream-media Transmission Technology in PACS and Distance Diagnosis

Objective To propose a stream-media technology based on the new transmission technology. Methods Firstly, we explored the advantages and disadvantages of exiting PACS image in LAN （Local Area Network） and WAN （Wide Area Network） and then expounded distance diagnosis related to HIS and PACS, VPN technology, wireless network applications, more points consultation applied technology. At last, we made an analysis of the characteristics of the stream-media transmission technology. Results The characteristics of low bandwidth occupied, high security, and high scalability of stream-media transmission technology fit the needs of PACS development. Conclusion Application of streammedia technology transferred in PACS image provides a new economical and practical technical solution to break through limitation of network bandwidth in medical imaging integrated information, and to thoroughly make use of medical resource.
