Individual stress analysis of a bone based on X-ray CT data provides useful information for diagnoses and medical treatments. Many studies on the stress analyses have been reported, however little attention has given to partial volume effect in the CT data. The partial volume effect may cause lower reliability in the analytical results because CT values on a bony part are changed by the effect. This paper proposes a method to correct CT values influenced by the partial volume effect. The correction method transforms CT values using a regression curve of an exponential function. The validity of the proposed method is confirmed by use of CT images of femurs of a pig and human mandibles.
