目的探讨降低计算机X线摄影的曝光量。方法以体模计算机X线摄影实验的方法,研究成像板X线曝光量与影像阅读器的宽容度和敏感度之间的关系,探讨低剂量计算机X线摄影曝光条件。结果计算机X线摄影低剂量值为平均曝光剂量的22.5%。结论低剂量计算机X线摄影可以实现。
Objective To explore how to reduce the exposure of computerized radiography. Methods The method of phantom computer X-ray photography was used to study the relationship between the X-ray exposure of the imaging plate and the tolerance and sensitivity of the image reader, and to explore the exposure conditions of low-dose computer X-ray photography. Results The low dose of computerized radiography was 22.5% of the average exposure dose. Conclusion Low-dose computerized radiography can be achieved.
