Abstract
Recently the technique of phase contrast imaging has become an useful and special tool in biology, material science etc. due to its high resolution. In this paper, we reconstruct the fly in a capsule, calibrate the misaligned geometry by sample information itself. The quality of the CT images is greatly improved and the efficiency of the calibration method is proved.
