基于虚拟专用网的互动式影像远程会诊体系的创建与初步应用

目的探讨互动式影像远程会诊系统的创建及其特点。方法下级医院局域网、防火墙[含虚拟专用网(virtual private network，VPN)功能]及不对称数字线路调制解调器(ADSL Modem)1套，联入Intemet，通过贵阳医学院附属医院防火墙接入本院VPN服务器，获得VPN隧道联入本院医学影像存储与传输系统(picture archiving and communication systems，PACS)服务器，使本院影像科诊断终端及下级医院能够共享同一影像数据。结果下级医院影像数据及检查信息能安全、无损的上传到本院PACS保存和管理，并进行会诊后将会诊结果以报告方式返回给下级医院。影像上传速度快，质量优良，操作互动性好。结论基于VPN的互动式远程会诊系统具有安全、快捷、互动性好、操作简便、实用可靠和优良的性价比等优点，值得推广。

Establishment and preliminary application of the interactive tele-radiologic conference system based on virtual private network

Objective To investigate the establishment and characteristics of the interactive tele-radiological system (IATRS) . Methods Local area network (LAN) of local hospitals with firewall and ADSL Modem was connected into internet, then connected into the Virtual Private Network (VPN) server of the affiliated hospital of GuiYang Medical College(GMCAH) through anti-firewall of GMCAH. The VPN tunnel was acquired and LAN of local hospitals was connected into the PACS server of GMCAH, resulting in sharing of radiological data by both the GMCAH and local hospitals. Results Radiological data from local hospitals could be transmitted by the PACS server of GMCAH safely and rapidly. The IATRS could provide high-quality images with high-speed, and with ease to perform. Conclusion IATRS is useful and reliable for transmitting radiological data between remote places.
