摘　　要：目的　探讨数字化立位全脊柱的成像技术。方法　在数字化X线设备上 ,分次采集全脊柱的影像数据 ,获得 2 2例受检者的正、侧位原图共 88幅 ,经图像工作站合成为 4 4张数字化全脊柱影像。选择同一体位的胸、腰椎片为配对组 ,测量每组图像的水平位移长度 ,分析其对脊柱侧凸角(Cobb角 )的影响。结果　每一配对组的胸、腰椎影像移位差异无显著性意义 (t =0 0 8～ 1 0 1,P >0 0 5 )。椎体移位每递增 1 7cm ,人体倾角 (α)发生± 1°的变化 ,对Cobb角影响极小 ,可以忽略不计。结论　在图像工作站实现数字化全脊柱的成像技术 ,对普及脊柱侧凸检查具有很好的推广应用价值。Objective To investigate the digital imaging technology in standing spine.Methods 88 (56 AP and 32 lateral) original spine images were collected in 22 cases on the digital X-ray equipment, and 44 total spine image (28 AP and 16 lateral) were composed by image workstation.By choosing the images of thoracic and lumbar vertebrae at the same position as the control, the transverse displacement and the deviation of Cobb angle were measured for comparing the efficacy.Results There was no significant displacement on the same position for thoracic vertebrae and lumbar vertebrae plain films (P>0.05).Body obliquity α changed ±1° when displacement increased every 1.7 cm, which showed little affect on Cobb angle and could be ignored.Conclusion The technique of digital spine imaging achieved in image workstation, which had special meaning for the popularization of total standing spine X-ray examination.
