| 介绍EOS成像系统的原理和技术背景，结合该技术的宣传说明和现有的文献报道，了解到低剂量EOS技术可以将检查过程中的辐射剂量降低5～10倍，而微剂量EOS甚至可以将辐射剂量降低至45倍；在成像质量方面相较于CR的图像质量只高不低；系统自带有EOS 2D和3D工作站，2D工作站可以帮助临床医生轻松实现对下肢冠状位和矢状位力线的测量和评估，在3D工作站进行三维模型重建后可以三维测量肢体的倾斜和扭转，利用这些测量结果，在进行术前评估、完善术前规划以及术后测量评估手术效果等方面给临床医生提供了极大的帮助。在测量的准确性方面，大量的文献报道认为EOS 2D测量和普通放射学测量精确度相当，而EOS 3D重建测量的精确度可媲美CT以及MRI。基于EOS的技术特点和优势，对其在评估下肢力线准确性方面的文献报道和研究进展作一综述。 |

| Introduction of EOS imaging system and its current research status in evaluating clinical value of lower limb force line |

| Abstract:The principle and technical background of EOS imaging system are introduced. Combining with the publicity of this technology and the existing literature reports,it is known that low dose EOS technology can reduce radiation dose by 5 to 10 times in the course of examination,and micro dose EOS can even reduce radiation dose by 45 times. The image quality is only high or low;the system has EOS 2D and 3D workstations,which can help clinicians to measure and evaluate coronal and sagittal force lines of lower limbs easily. The tilt and torsion of limbs can be measured three-dimensional after three-dimensional model reconstruction in the three-dimensional workstation. Using these results,preoperative evaluation can be carried out. It is helpful for clinicians to evaluate and improve preoperative planning and post-operative measurement and evaluation of surgical effect. In terms of measurement accuracy,a large number of literatures reported that the accuracy of EOS 2D measurement is comparable to that of general radiology measurement,while the accuracy of EOS 3D reconstruction measurement is comparable to that of CT and MRI. Based on the technical characteristics and advantages of EOS,this paper reviews the literature reports and research progress of EOS in evaluating the accuracy of lower limb alignment. |
