Abstract

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.
