摘要
【目的】构建一种高性能低成本的存储方式,来保存320排CT动态容积检查所生成的大量的数据。【方法】使用大容量硬盘和免费的PACS服务器端软件构建放射科部门级PACS(mini-PACS)服务器,并使用网络流量检测软件检测mini-PACS的平均网络流速。随机抽取12份我院320排CT肝脏全器官灌注动态容积数据,进行mini-PACS的存储操作,将其所用时间与全院级PACS(full-PACS)和刻录DVD光盘存储进行比较。最后计算mini-PACS的成本。【结果】构建mini-PACS在最高时段的平均网络流速为5 940 Kbps。用mini-PACS、full-PACS和刻录DVD光盘3种方式存储320排CT肝脏全器官灌注动态容积数据所用的时间分别为(823.8±17.9)s、(833.1±10.2)s和(1541±37.1)s,对其分别配对t检验(P<0.05),差异有统计学意义。并且mini-PACS单位容量所需费用仅为1.91元/GB。【结论】构建mini-PACS可以高性能低成本地解决320排CT动态容积数据的存储问题。
[ Objective] To construct a storage system with high capability and low cost, that can save the huge amount of volume data produced by 320-row CT. [Methods] A mini-PACS sever was built with a 1.5 TB hard drive and free PACS sever software. Network flow detection software was used to detect the mean net speed of the mini-PACS. Twelve random sample full liver organ 320-row CT perfusion volume data were used to storage by mini-PACS, and the seconds used were compared with those of full-PACS and burning DVD. Finally, the cost of mini-PACS was calculated. [Results] The mean net speed of mini-PACS was 5940 Kbps at rush hour. The seconds used by mini-PACS, full-PACS and burning DVD were 823.8 ± 17.9 s,833.1 ± 10.2 s and 1541 ± 37.1 s. Significant differences were observed among all groups （P〈0.05）. The cost of mini-PACS was 1.91 Yuan per GB. [Conclusions] Constructing mini-PACS in this way can solve the storage problem of volume data produced by 320-row CT.
