摘　　要：目的探讨小儿胸部摄影技术中成像角度的运用与影像质量的关系。方法采用随机抽样方法将前来放射科摄片的300例小儿随机进行常规（对照组）和适度地将中心线向足侧倾斜一定角度（5°，实验组）的2种摄片方法摄影。分析2种方法的差异性。结果2种不同的小儿胸部摄影方法在影像质量上存在显著性差异（P〈0．01）。实验组肺野显示分率高于对照组，有利于肺纹理的连续追踪。结论适度地将中心线向足侧倾斜一定角度（5°）的成像方法，可提高小儿胸片的影像质量。Objective To study the aplied value of imaging photographed angle in chest radiography m children. Methods 300 children were selected randomly from those had going to take chest radiography in this study. All cases underwent both conventional chest radiography （control group, 150 cases） and chest radiography using an imaging photographed angle of X--ray toward the foot about 5°（experimental group, 150 cases）. The image quality of these two groups was analysed comparatively. Results There was significant difference between control group and experimental group in image quality（P〈0.01 ）. The lungs were showed better by experimental group than that by control group. Conclusion The application of imaging photographed angle （ the centre line of X-- ray toward the foot 5°） can improve the image quality in chest radiography in children.
