基于带宽感知动态压缩算法的PET/CT影像传输策略OA北大核心CSTPCD
TRANSMISSION STRATEGY OF PET/CT IMAGE BASED ON BANDWIDTH-AWARE DYNAMIC COMPRESSION ALGORITHM
针对网络带宽不断变化以及PET/CT影像数据量大引发的过量传输请求命令,提出一种基于带宽感知动态压缩算法的PET/CT影像高效传输策略,简称T-PCI策略.该策略首先依据序列信息进行影像序列化打包,同时监测当前网络的实时带宽,采用带宽感知动态压缩算法和边压缩边传输机制,实现海量影像传输.仿真实验结果表明,与三种常规传输模式相比,T-PCI策略以实时带宽和边压缩边传输为基线,其传输总时间可降低19％～58％,有效提高传输效率.
Aiming at the constantly changing network bandwidth and the excessive transmission request command caused by the large amount of PET/CT image data,this paper proposes a PET/CT image transmission(T-PCI)strategy based on bandwidth-aware dynamic compression(BADC)algorithm.This strategy performed image serialization and packaging based on sequence information,while monitoring the real-time bandwidth of the current network,using BADC algorithms and compression-while-transmission mechanisms to achieve massive image transmission.The simulation results show that compared with the three conventional transmission modes,T-PCI strategy uses real-time bandwidth and compression-while-transmission as the baseline,and its total transmission time can be reduced by 19％-58％,which effectively improves the transmission efficiency.
