目的：探讨手动曝光控制（简称手控模式）与自动曝光控制（简称自控模式）哪种操作模式能够提高婴幼儿胸部数字化X线摄影（DR）的图像质量，提高摄影成功率，降低辐射剂量，减少重照次数。方法：日常工作中用手控模式与自控模式各摄影婴幼胸部DR片100例，对两组的图像质量，摄影成功率，辐射剂量等进行对比分析。结果：手控模式甲级片高于自控模式，辐射剂量低，重照次数少。结论：手动曝光控制更适用于婴幼儿胸部DR摄影，婴幼儿胸部DR图像甲级片率更高，患儿整体辐射剂量降低，重照率降低。
目的：探討手動曝光控製（簡稱手控模式）與自動曝光控製（簡稱自控模式）哪種操作模式能夠提高嬰幼兒胸部數字化X線攝影（DR）的圖像質量，提高攝影成功率，降低輻射劑量，減少重照次數。方法：日常工作中用手控模式與自控模式各攝影嬰幼胸部DR片100例，對兩組的圖像質量，攝影成功率，輻射劑量等進行對比分析。結果：手控模式甲級片高于自控模式，輻射劑量低，重照次數少。結論：手動曝光控製更適用于嬰幼兒胸部DR攝影，嬰幼兒胸部DR圖像甲級片率更高，患兒整體輻射劑量降低，重照率降低。

Objective:To investigate either manual exposure control or auto exposure control can improve image quality of digital radiography, to raise success rate of photography,to reduce radiation dose and reirradiation times. Method:One hundred images of infant chest digital radiography by manual exposure control and auto exposure control were taken respectively. The images between the two groups were analyze by image quality,success rate of photography and radiation dose. Result:The rate of grade A images were higher by manual exposure control than auto exposure control,with low radiation dose and reirradiation times. Conclusion:Manual exposure control is more suitable for infant chest digital radiography,which can raise the rate of grade A image,reduce radiation dose and the rate of reirradiation.
