我厂生产的仿苏200毫安X线机结构落后,性能较差。用户反映:照象效果不好,穿透力弱,如腰椎正侧位都投照不出来。针对这些问题,我厂对大批生产的W771型X线机的内在质量,尤其是侧重千伏误差及其有关问题,作了大量的科学实验工作,我参加了这项工作。在实践中,对X线机千伏补偿的性质,有了一点浮浅的认识,并对它作了一点定性、定量分析,大致情况扼要总结 My factory production of imitation Su-200 mA X-ray machine behind the structure, the performance is poor. Users reflect: poor image effects, penetrating power is weak, such as the lumbar lateral projection are not come out. In response to these problems, I plant a lot of production of W771 X-ray machine intrinsic quality, especially focusing on the kilovolt error and related issues, made a lot of scientific experiments, I participated in this work. In practice, there is a little superficial understanding of the nature of X-ray machine kilovolt compensation, and a little qualitative and quantitative analysis on it. The summary of the general situation
