远程医疗会诊中通信技术的研究与应用

远程会诊是远程医学的重要组成部分,它是指利用多媒体技术在各种通讯载体上进行各类医疗活动。远程医疗主要应用于公共卫生和各种医学数据库的检索、远程医疗会诊和门诊、远程医疗、远程检查、远程监护、远程教学及各项医疗事故的远程管理。近年来网络技术和多媒体技术的发展,促进了通信技术的综合化,数字化,智能化发展。 本文基于以上背景,着重研究了远程会诊系统中的通信技术并应用到本人开发的系统中,具体内容如下: 研究分析国内外现状,以往远程医疗一般是使用视频会议系统进行双方的通信。病人信息和诊断图像通过视频方式传递,图像质量得不到保证,并且没有严格的监管性。为了改变这一弊端。将该系统分为两个模块:医疗数据传输模块和视频会议模块,分别采用不同的协议进行传输。医疗数据传输模块采用DICOM协议进行传输,结合DICOM传输过程和层次性的特点以及TCP/IP网络协议分层结构,提出了一种新的DICOM标准的网络模型,视频会议模块采用RTP/RTCP协议和IPv6协议进行多媒体数据传输,并通过RSVP协议对其优化。客户端与服务器端底层都采用了线程池模式设计,即可以通过调节节点机的硬件配置的同时调节接受通讯请求数量的上限,以达到最佳的负载平衡,发挥出每台节点机最优的性能。
