Background, Motivation and Objective Adolescent idiopathic scoliosis (AIS) is a three-dimensional deformity of the spine. Researches have indicated that osteopenia is a common phenomenon in scoliotic patients. Quantitative ultrasound (QUS) has been used to assess skeletal status, and the results demonstrate a good correlation with bone mineral density (BMD) using DXA method. Recently ultrasound imaging using reflection signals from vertebra has been applied to measure the severity of spinal curvature in AIS children, and the results show consistency with the measurements from radiography. The objectives of this study are to develop a method which can extract parameters from ultrasound signals to determine bone quality of vertebra and to investigate if the severity of spinal curvatures can be differentiated by the derived parameters.
