DR数字影像对幼儿手指创伤的各种改变几乎都能显示,但由于幼儿手指是幼儿身体结构中天然对比较差的部位,对X线影像设备要求较高。不同的DR影像设备,拍摄出的照片其清晰度和对比度差异较大,造成一些疾病容易漏诊。因此,在DR影像系统操作中,应充分考虑成像系统影像的形成因 DR digital images of children’s finger injuries almost all changes can be displayed, but because children’s fingers are young children’s body structure of the poor natural comparison of the parts, higher requirements for X-ray imaging equipment.
