摘　　要：提出了基于云计算的医学图像流媒体服务传输系统,此系统将医疗设备和PACS进行整合,将来自于各个医疗设备的图像用扫描仪扫描为数码图像,并以流媒体的形式实时提交给远程服务器端。在云数据库虚拟化存储平台上,用先进的流媒体技术解决了医疗资源共享和高分辨率图像连续存储问题。实验结果表明,与传统服务器在LAN(Local Area Network)、TANet(Taiwan Academic Network)和家庭网络中使用FTP传输相比,建立的云计算医学图像流媒体服务传输系统的网络传输率分别提高了45.6%、49.4%和8.1%。This paper proposed the medical image streaming media transmission system based on cloud computing, which integrates medical devices and PACS. The system makes use of scanning to transform images from different me- dical into digital images which are submitted to the remote severs real time in the form of streaming media. In the virtual storage platform of cloud database, the paper adopted advanced streaming media technology to solve the problems of sharing medical resource and storing continuously high resolution images. The experimental results show that compared with the transmission rates of traditional servers using FTP in LAN（（Local Area Network）, TANet（Taiwan Academic Network） and the home network, the transmission rate of the medical image streaming media transmission system based on cloud computing rises respectively 45.6% ,49. 4% ,8. 1%.
