PROBLEM TO BE SOLVED: To solve such a problem that high speed high accuracy alignment of transmission image is impossible for the wide sample, inclination angle conditions, in the reconstruction of three-dimensional image of a transmission image.SOLUTION: In an imaging sequence for inclining a sample at a predetermined angle step, and acquiring first through N-th images for every inclination angle, the sample is aligned based on the results of three-dimensional phase correlation of a first reverse projection line image volume, and a second reverse projection image volume, corresponding to a temporary second image when the sample is inclined by 1 step, and then a second reverse projection line image volume corresponding to the second image of the sample after the alignment is determined as the reconstruction data. |
