多学科专家(物理学家、生物力学工程师、医学放射科医生和儿科整形外科医生)之间的密切合作导致了一种名为EOS的新的低剂量辐射设备的开发。EOS有三个主要优点：-使用乔治·查帕克(1992年诺贝尔奖)发明的气体X射线探测器，获得骨骼系统2D图像所需的剂量减少了8到10倍，而从CT切片获得3D重建所需的剂量减少了800到1000倍。-EOS获得的3D重建的准确性与CT一样好-患者在站立(或坐着)位置进行检查，并从头部到脚同时进行正侧扫描。这是与传统CT相比的一个主要优势，传统CT要求患者水平放置。-骨关节系统每个元素的3D重建与传统CT EOS获得的重建一样精确，而且速度也很快，只需15至30分钟即可对整个脊柱进行成像。
Close collaboration between multidisciplinary specialists (physicists, biomecanical engineers, medical radiologists and pediatric orthopedic surgeons) has led to the development of a new low-dose radiation device named EOS. EOS has three main advantages: -The use of a gaseous X-ray detector, invented by Georges Charpak (Nobel Prizewinner 1992), the dose necessary to obtain a 2D image of the skeletal system has been reduced by 8 to 10 times, while that required to obtain a 3D reconstruction from CT slices has fallen by a factor of 800 to 1000. - The accuracy of the 3D reconstruction obtained with EOS is as good as that obtained with CT - The patient is examined in the standing (or seated) position, and is scanned simultaneously from head to feet, both frontally and laterally. This is a major advantage over conventional CT which requires the patient to be placed horizontally. -The 3D reconstructions of each element of the osteo-articular system are as precise as those obtained by conventional CT EOS is also rapid, taking only 15 to 30 minutes to image the entire spine.
