Correction of center of rotation and projection angle in synchrotron X-ray computed tomography

Abstract An error in tomographic reconstruction parameters can result considerable artifacts in the reconstructed image, particularly in micro-computed tomography and nano-computed tomography. This study involved designing an automatic method for efficiently correcting errors resulting from incorrec...
