Titel A tool for computer aided measurements of 3D curvature of the spine in scoliosis patients
Sammanfattning Scoliosis is a congenital disease caused by a complex three-dimensional deformity of the spine. Traditionally, the disease is diagnosed by measuring the angle between two vertebrae in the coronal plane, the so called Cobb angle. Many methods have been suggested to obtain a true measure of scoliosis in three dimensions. We suggest a method inspired by image registration techniques to describe the entire curvature using 3D image data from spiral Computed Tomography. The method lets the user view three orthogonal slices of the dataset and interact with them until they match each other visually, thus obtaining information of the six degrees of freedom for a rigid body transformation. This has been implemented in a program that could be run on any computer. Comparison with another metod for calculating vertebrae angles have been done. The other method has a more automatic approach.
