Abstract

When there is the material that is high absorbency such as metal in the object, X-ray CT image often has artifacts that are abnormal findings. This artifact is called metal artifact. Metal artifact can be obstacle when examining objects accurately. Therefore, it is expected that artifact is reduced by a user of X-ray CT. To reduce metal artifact, various methods have been studied but any methods are not compatible with shape of the object and removing metal artifact. In this study, we applied the method with discriminant analysis method and sin curve interpolation. As a result, we could almost remove metal artifact and keep shape of object. However, cross artifact was left in the nonmetal part in the method.
