Abstract:

Abstract： Symmetry is common in human body. It may be a sign of pathology when a human organ appears more asymmetric than others. Based on the mathematical asymmetric theory, an asymmetric computing model of 3D medical image is presented. A numerical method and computing framework are studied. The method can be used to diagnose cholesteatomatous chronic otitis media by numerical experiments. Taking doctors’ diagnosis as the reference, the ratio of numerical diagnosis accuracy of cholesteatoma is up to 82.0%. The asymmetry computing model has both measurable and objective properties so that it can be extended to other computerassisted diagnosis related to medical asymmetry.

Key words: asymmetry computing; 3D medical image; cholesteatoma diagnosis; computer assisted diagnosis; computing model
