Segmentation of vertebral bones in computed tomographic data is important as a first stage image-based radiological tasks. However, it challenging problem to segment an affected spine correctly. In this study, we propose new method segmentation thoracic and lumbar bodies from thin-slice images. Especially, focus on deformable model-based scheme confirm the feasibility clinical sets with various bone diseases, such metastases scoliosis. As application algorithm, virtual straightening thoracolumbar also performed. Results database 16 patients indicate applicability our spines by scoliosis multiple metastases.
