Computer-Aid Cobb Measurement of Scoliosis Using Deformable Model with Fuzzy Spatial Relations
Scoliosis is a disorder that causes an abnormal curve of the spine, or backbone. Treatment decisions for scoliosis are based on consideration of the patient’s physiologic maturity, curve severity, curve location, cosmetic concerns, and the estimated potential for progression. In order to reduce the observer variability in radiographic scoliosis assessment, we developed a semi-automatic method for measuring the Cobb angle using deformable model with fuzzy spatial relations integrated and our algorithm applying on the final contour of the model. In experiment, the method proves it is faster and requires less manipulation than the manual method. Also, this method does not require any special qualifications, skills or trainings to use it. Therefore it can be developed to make portable software which could be widely used by the healthcare providers.
