改良双下肢站立位全长X线摄影、拼接技术在全膝关节置换术中的应用价值
|
摘要
目的:探讨无自动拼接功能的普通DR机采用改良双下肢站立位和拼接技术在全膝关节置换术中的应用价值。方法:在数字化X线设备上,采用相同焦片距、X线视野、球管中心及曝光条件分三次采集双下肢站立位的影像数据,获得60例受检者的原始图像180幅,用Microsoft office Excel及Pic Pick软件合成60张数字化双下肢站立位全长X线片,对拼接好的双下肢全长X线片按照包括部位、图像清晰度、全片密度有无差异、拼接线是否明显、全片各部位是否失真来评价照片质量并对膝关节畸形的对线异常原因进行测量分析。结果:双下肢图像拼接成功率达95%,拼接后的图像组织密度相同,图像清晰,视觉连贯,能对膝关节畸形的对线异常原因进行准确测量分析。结论:改良双下肢站立位全长X线摄影、拼接技术在全膝关节置换术中具有一定应用价值,值得在基层医院推广应用。
Objective: To explore the application value of improved double lower limbs full-length standing X-ray photography, splicing technology in total knee arthroplasty. Methods: We used the image data collected by same focal distance, Xray vision, the tube center and exposure conditions points three times, obtaining 180 pieces from 60 patients by digital X-ray equipment. Using Microsoft office Excel and Pic Pick software to synthesise over 60 pieces of digital double lower limbs standing X-ray film, and to analyze the stitching double lower limbs length X-ray film, including the sites, image clarity, film density to see whether they have obvious differences, to evaluate the quality of image distortion and the reason of the knee joint deformity of abnormal line measurement. Results: The success rate of double lower limbs image matching is up to 95%.Besides, after mosaics of images tissue density is the same, and the image is clear and coherent. Most importantly, it can accurately measure and analyze the cause of abnormal line in knee joint deformity. Conclusion: The improved double lower limbs full-length standing X-ray photography, splicing technology has certain application value in total knee arthroplasty, and is worthy of popularization and application in grassroots hospital.
