| Abstract: | An alignment method for correction of the axial and radial runout errors of the rotation stage in X‐ray phase‐contrast computed tomography has been developed. Only intensity information was used, without extra hardware or complicated calculation. Notably, the method, as demonstrated herein, can utilize the halo artifact to determine displacement. |
