摘要
1992年法国物理学家乔治·夏帕克发明了一款新型X线探测器,并促进了EOS 2D/3D影像采集系统的发展。这是一款超低剂量的X线影像设备,扫描原理是在患者负重位下同时进行人体正侧位全身线性扫描,同时获得正侧位两张2D影像,根据2D图像骨骼标志的识别进行3D建模,超过100个临床骨骼数据自动生成(包括脊柱,骨盆和下肢),精准度高,避免人为测量误差,极大地满足了脊柱外科与骨科临床需求,在精准医疗的发展过程中,或将成为骨放射领域新的评价标准。
A French physicist,Georges Charpak,invented a novel X-ray detector in 1992,facilitating the development of EOS2D/3D imaging system.The X-ray detector is an ultra low-dose X-ray device.The principle of scanning is performing simultaneously anteroposterior and lateral whole body linear scan for patients in weight-bearing position,obtaining two 2D images of anteroposterior and lateral positions.Bone landmarks in 2D images are recognized for 3D reconstruction.Over 100 clinically relevant osteoarticular measurements are automatically calculated from 3D models（including the data of spine,pelvic,and lowlimb）.With the development of precision medicine,the evaluation based on EOS imaging,which shows a high accuracy,avoiding artificial errors and satisfying the clinical needs of spinal surgery and orthopedic department,may become a novel evaluation standard in osteoarticular radiology filed.
