The sterEOS X-ray machine is capable of a simultaneous capture of biplanar X-ray images by slot scanning of the whole body in physiological load-bearing position. The simultaneous capture of spatially calibrated anteroposterior and lateral images provides a three-dimensional (3D) surface modelling of the skeletal system using sterEOS 3D software. The relevant clinical parameter such as spinal and vertebral parameters are supposed to be measured. The aim of this study is to evaluate an accuracy of EOS measurement of spinal alignment. A phantom for X-ray imaging was used for CT scanning and sterEOS X-ray imaging. 3D surface models of a phantom were reconstructed from its CT images. The same clinical parameters measured from CT-derived 3D surface models and sterEOS 3D software were compared.
