Three-Dimensional Assessment of Scoliosis Based on Ultrasound Data

摘要

In this study, an approach was proposed to assess the 3D scoliotic deformity based on ultrasound data. The 3D spine model was reconstructed by using a freehand 3D ultrasound imaging system. The geometric torsion was then calculated from the reconstructed spine model. A thoracic spine phantom set at a given pose was used in the experiment. The geometric torsion of the spine phantom calculated from the freehand ultrasound imaging system was 0.041 mm~(-1) which was close to that calculated from the biplanar radiographs (0.025 mm~(-1)). Therefore, ultrasound is a promising technique for the 3D assessment of scoliosis.
