目的 探讨DR全下肢全景成像技术及在膝关节置换术中的应用价值。方法 回顾分析我院2014年2月～2017年4月收集233例全下肢摄影患者资料，应用西门子成像系统、YSIO采集系统DRX线机全下肢摄影功能软件，立式全下肢专用架，获得全下肢无缝拼接影像，经图像处理后应用测量软件进行相关数据测量。结果 231例患者全下肢全景成像拼接成功。拼接处无痕迹，无运动等伪影。2例因患者移动致图像拼接错位判定不合格，经重新投照后获得满意图像。结论 全下肢成像技术，一次曝光，通过无缝拼接技术，在一张胶片上显示全下肢全景影像，为矫形术前、后的疗效观察提供了高质量的全景解剖图像。 srteAbstract：Objective To evaluate DR panoramic imaging of lower extremity and its application in knee arthroplasty.Methods From February 2014 to April 2017，we retrospectively analyzed the data of 233 cases of lower extremity radiographs in our hospital. Application of Siemens imaging system，YSIO acquisition system DRX line all the lower limbs photographic function software，vertical full lower limb special frame，access to seamless lower limb full stitching images，the application of measurement software after 静压主轴
the image data measurement.Results The panoramic images of 231 patients were successfully stitched.There was no trace，no movement and so on.2 cases were disqualified because of the dislocations caused by the movement of the patients.They were satisfied with the image after re-projection.Conclusion The whole lower extremity imaging technique，one exposure，can display the panoramic image of the whole lower extremity on a piece of film by seamless splicing technology.A high-quality panoramic anatomic image was provided for the preoperative and postoperative observation of orthopaedic treatment.
