医学影像存档与通讯系统影像诊断客户机的硬件配置对调用图像速度的影响

Influence of hardware on the velocity of film-view-client of picture archiving and communication system

目的:分析影响医学影像存档与通讯系统(picturearchivingandcommunicationsystem,PACS)影像诊断客户机调用图像速度的关键因素,以选择适合的硬件配置方案。材料与方法:通过调换两组不同档次的中央处理器(centralpro-cessingunit,CPU)、随机存储器(内存,randomaccessmemory,RAM)、显卡、硬盘和主板来测试计算机各部分配件对速度的影响。结果:CPU和主板对速度的影响最大,硬盘和内存对速度的影响较小,显卡对速度没有影响。结论:在配置客户机时应将主要资金投入到CPU和主板上,硬盘和内存只要容量够用即可,显卡则不用投入过多资金。

Objective:To find out the key factors that influence the computer speed,and to make out a proper project to gain an optimal speed?cost value.Material s and Methods:To determine the influence of each hardware on computer's speed by switching the hardware of computer.Results:CPU and mainboard have a great influence on speed;hard disk driver(HDD)and RAM have a minor influence on speed,and video card has no influence on speed.Conclusion:High-speed CPU and mainboard should be used.HDD and RAM's quantity should be enough,their speed are not important.A cheap video card will work.
