| 摘 要： | 目的探讨计算机X线摄影的正确曝光条件,在保证影像质量的情况下,降低被检者辐射剂量。方法利用konica 170 CR系统,选择胸部后前位、腰椎前后位、膝关节前后位3个摄影位置,60例患者分别以不同的KVP和mAs曝光,分析对比影像质量。结果适当的高KVP(90～105)摄影,可以降低X线曝光量3.57～5.00倍,影像质量无差异。结论 CR高KVP摄影,降低X线曝光量,降低被检者辐射剂量。

| Abstract: | Objective To study CR in the correct exposure condition,ensure the cases,image quality reduce a patient radiation dose.Methods Use konica 170 CR system,choose three parts,60 patients,KVP and mAs respectively by different exposure,the value analysis image quality Results Appropiate high KVP radiography exposure about 3.57-5.00 time,image quality there is no obvious differences.Conclusion CR high KVP photography reduces the X-ray exposure,reduced the patient radiation dose. |
