摘　　要：X线机MAS和曝光时间校准表是保证X线机出线质量所必须的校准仪表.为提高其性能价格比,我们应用了电压—频率(V/F)转换技术,采用计数器计数及显示器显示输出等信号处理方法,对该表测试原理及信号处理方式进行了全新设计.使其具有了精度高、价格低等特点.MAS and exporsure time calibrator is a useful calibrating instrument for enssuring the quality of X-ray apparatus. At present,the market price of digit calibrator is very high and the use of rotary exposure by tiny hole instead has the disadvantage of low precision. Here,we developed a new design of V/F transfer, counter and display technology of the MAS and exporsure time calibrator for the measurement of parameter of MAS and exporsure time.
