3D Ultrasound Parametric Modeling Imaging for Spine Deformity – A Preliminary Study

Ultrasound (US) imaging has been applied to the assessment of scoliosis. However, current ultrasound techniques cannot provide a good 3D visualization of spine structure, and the output images are difficult to interpret and measure for clinicians without ultrasound practice. The objectives of this study are to construct the 3D spine model image for scoliotic subject and to implement the model image for the proxy Cobb angle measurement. US measurement parameters including lamina indicator (LAI) and axial vertebral rotation (AVR) are used to generate the model. Coronal projection of the model are used as proxy radiograph to measure the scoliotic curvature. The result model visually shows the 3D deformity of spine and improves the spine curvature measurement result.
