Abstract
The present invention provides a method for spine position detection, comprising: obtaining 2D geometrical configuration of a current vertebra body selected from a plurality of vertebra bodies visible in an image on a sagittal plane defined by a horizontal component of an initial point, a geometrical template being applied to the current vertebra body and the 2D geometrical configuration of the current vertebra body being adjusted by a predetermined correlation evaluation; searching adjacent edge points of next vertebra body corresponding to a number of edge points of the current vertebra body by identifying the gradient values along the direction substantially perpendicular to the edge of the current vertebra body based on the adjusted 2D geometrical configuration of the current vertebra body; calculating height of an intervertebral disc located between the current vertebra body and the next vertebra body based on an average of the distances between the edge points of the current vertebra body and the corresponding adjacent edge points of the next vertebra body; determining 2D geometrical configuration of the next vertebra body based on the height of the intervertebral disc and th…
