摘　　要：目的:探讨全下肢一次曝光数字化拼接成像技术的临床应用。方法:利用FCR XG5000阅读器,FUJI DRY7000激光相机,超长规格IP板,其大小尺寸为35.4cm×83.7cm,相当于两张14×17片竖放。患者面向球管站立于紧贴IP板,使患者骨盆至踝关节完全包括在IP板的范围内,利用CR自带的全下肢拼接软件,对120例身高150cm～175cm的患者一次曝光拍摄拼接成负重立位双下肢全长影像。结果:120例患者双髋关节、股骨、膝关节、胫腓骨及踝关节影像均能清晰显示,密度基本一致,下肢力线测量点显示清晰,为髋、膝关节置换术术前计划和术后评估随访提供了可靠的影像依据。结论:合理应用CR的投照技术和图像后处理拼接软件,能获得双下肢全长拼接的优质图像,为双下肢的疾病诊断和手术评估提供准确可靠的影像资料。Objective To approach the clinical application of one time exposure and digitized splicing imaging technique for the whole low extremities.Methods To utilize FCR XG5000 reader, FU JI DRY7000 laser camera and ultralong stand imaging plat (IP). The length of IP is 35.4 cm multipy 83.7 cm, corresponding to erecting two 14×17 film. Facing tube,patients standed before self-made support. From pelvis to ankles were wholly included in IP,sextent. To utilize CR splicing software for whole low extremities,120 cases(b...
