captures a large number of points from the surface of the spine, at which an optical raster image is created by the source of light. The resulting effect is a real representation of the torso relief, capturing even the smallest asymmetry and revealing any variation in the geometry of spine and pelvis. This is followed by immediate digital processing by means of computer triangulation. Mathematical correlation model then provides a graphical 3D reconstruction of the position of the entire spine from the rear, side and also in axial representation
