Abstract
Reliable stress analysis of a bone requires not only precision in shape of the finite element model but also proper setting of material constants for the model. This study proposes two methods to recognize proper shape and to evaluate mechanical properties from X-ray CT images. The former method corrects CT values considering influence of partial volume effect. The latter interpolates outlines of an object in muti-sliced CT images. This paper shows that these methods perform a proper correction and a clear interpolation using CT images of an acrylic cylindrical specimen.
