摘　　要：目的:讨论移动DR在大规模体检当中的实际应用价值。方法:抽取体检中使用移动DR所照的胸部图像与院内普通DR图像各500例进行比较,并取300例移动DR所摄胸部图像与等量X线透视印象按照不显示、显示、显示清晰3方面进行比较。结果:移动DR与普通DR在图像清晰度及层次分辨率效果媲美,在显示细微结构等方面明显优于透视。结论:移动DR图像能媲美普通DR的图像分辨率,并具备普通DR机所不具备的便携、移动性良好等优势,完全能满足大规模院内、外体检工作需要。Objective To discuss the application value of the mobile DR in large-scale physical examination. Methods Compared each 500 chest images that collected for the physical examination by the mobile DR, direct digital radiography（DR）, then did another comparison about each 300 chest images of mobile DR and phnendoskiascope, recorded them by no displayed, displayed and limpid-displayed. Results The resolution of images collected by the mobile DR was comparative with the ones collected by direct digital radiography, better than phnendoskiascope in showing details. Conclusion The mobile DR images have a, good resolution ratio as DR images have, meanwhile, this machine is easy to be taken and removed Examination while DR could not, and therefore the machine can do large-scale physical whatever inside or outside.
