Fast semi-automatic stereoradiographic reconstruction of scoliotic spines using multi-scale image processing and statistical geometric models

Abstract We propose a fast stereoradiographic reconstruction method for the spine. Semiautomatic detection of the vertebral bodies' corners is obtained using splines, multi-scale analysis and dynamic programming. These points, combined with calibration data, delimit a hexahedron in space where we can match the vertebral body. This hexahedron is then passed through a 3D statistical database built using local and global information generated from a bank of normal and scoliotic spines. Finally, models of the vertebrae are positioned with respect to these landmarks, completing the 3D reconstruction.
