| Research Abstract |
The purpose of the present study is to reduce the artifacts in image reconstruction of X-ray CT in order to improve three-dimensional measurement accuracy. Other than the target artifacts, actual data of X-ray CT contains various factors leading to the degradation of accuracy. Therefore we developed a X-ray CT simulator to generate simulated data which only contains the intended factor of the artifact. Furthermore we developed the correction method of the partial volume artifact which deteriorates the accuracy in the direction perpendicular to the slice plane and confirmed that the error in a longitudinal direction could be reduced about 60% without degrading the S/N ratio of the reconstructed image.
