| 摘 要： | 目的:探讨腹部摄影自动曝光控制探测点组合选择。方法:把不同探测点的组合作为唯一变量,对5个组合进行自愿者腹部的摄影,每种组合进行中等体型自愿者用80kV摄片3张,根据资料确定评价点,并测量各评价点的密度值。结果:5种探测点组合中,只有“左+中+右”这组探测点组合各评价点密度值达到或最接近标准值;其他探测点组合都有不同程度偏离。结论:建议使用“左+中+右”这组探测点组合作为腹部摄影自动曝光控制探测点组合的常规选择。

| Abstract: | Objective:Investigate the component pattern of detecting points in automatic expo-sure control of abdomen radiography.Methods:Taking the different combinations of detecting points as a single parameter,radiographies of voluntary abdomen in five kinds of combination were obtained.Three80Kv radiographies of voluntary celiac in every kinds of combination were taken.All the data were treated,compared and analyzed on the basis of selecting evaluate points and density of each e-valuate point.Result:Only the density of″left+middle+right″detecting point was close to standard value in all five combinations.The densities of the other evaluate points were higher or lower.Con-clusions:The″left+middle+right″combination is better in routine selection of abdomen radiography. |
