摘要 根据最新国际电工委员会标准IEC62220-1,我们对我院数字X线平板探测器系统的物理特性进行测试。设计建立符合IEC标准的实验测试设备和测试方法,并对某些测试条件对测量结果的影响进行初步研究。 DQEs for a digital X-ray flat panel detector system has been measured in accordance with the new international standard IEC 62220 - 1. A measurement set - up complying with IEC 62220 - 1 has been realized, the influence of measuring set- up was evaluated in this paper
