Abstract:
1. A method for multi-dimensional visualization of a spinal column/spinal deformities comprising the steps of obtaining an image of a spinal column definitely showing each vertebral body in the spinal column; analyzing each vertebral body and defining mathematical/geometrical characteristic parameters uniquely characterizing respective vertebrae; preparing vectors comprising an initial point ( defining a three-dimensional coordinate system with an axis x formed by an interacetabular line connecting two acetabular centers ( scaling and calibrating the coordinate system based on the length of the interacetabular line in the horizontal plane view; determining coordinates of initial point ( determining coordinates of the left and right pedicular centroids ( taking interpedicular line (IPPC) as an interpedicular vector and choosing the initial point determining the direction of the interpedicular vector as the pedicular centroid more distant from the axis x; calculating coordinates of the interpedicular vector; determining a coordinate system for positioning the vertebra vectors by the position of the two acetabular centers of the pelvis; defining a sacrum vector and calculating sacrum vector parameters; defining pelvis vectors based on a predetermined sacrum vector; calculating parameters for the pelvis vectors based on the predetermined sacrum vector; defining a sacrum plateau vector and calculating sacrum plateau vector parameters; defining pelvis vectors based on a predetermined sacrum plateau vector; calculating parameters for the pelvis vectors based on the predetermined sacrum plateau vector; measuring pelvic parameters by said sacrum vector and pelvis vectors based on said sacrum vector; visualizing the spine in a three-dimensional manner in the thoracic and lumbar region with said vertebra vectors complemented with sacrum vector and pelvic vectors.
