【摘要】 本文共分为两部分，第一部分针对现代辐射扫描成像系统对投影数据获取技术在快速、高密度方面的需求，提出一种新型多阶段多层次流水线结构，大幅度降低了投影数据采集系统的死时间，提高了系统的响应速度；第二部分着重介绍以ＴＣＰ／ＩＰ协议为基础，采用以太网和网络编程技术实现异种机间、异种操作系统间底层的海量数据的实时传输与通讯的方案、拓朴结构、实现技术以及影响传输率的几个因素和实验数据。更多还原

【Abstract】 This paper is consisting of two Parts. The first part is aimed for fast data acquisition tech- nology of high density projection,A new type of pipeline,which has multi-stage and hierarchi- cal structure, was developed. By this pipeline, the dead time of the data acquisition system was greatly reduced,and then the throughput of the whole system was increased.In the second part, the scheme,topology and network programming techniques have been introduced for mass data on-line transfer and commnunication between different computers(PC and /workstation)and different operation systems(DOS and UNIX)based on Ethernet and TCP/IP,Also it has discussed the experimental data and some factors that affect the transfer rate.(更多还原
