A method for segmenting vertebrae in digitized images includes providing a plurality of digitized whole-body images, detecting ( 91 ) and segmenting a spinal cord using 3D polynomial spinal model in each of the plurality of images, finding ( 92 ) a height of each vertebrae in each image from intensity projections along the spinal cord, and building ( 93 ) a parametric model of a vertebrae from the plurality of images. The method further includes providing a new digitized whole-body image including a spinal cord, fitting ( 94 ) an ellipse to each vertebrae of the spinal cord to find the major and minor axes, and applying ( 95 ) constraints to the major and minor axes in the new image based on the parametric model to segment the vertebrae.
