In a radiation tomography device, in case a wide photographing area is required, even if a resolution capability in a depth direction of a section of a subject including an intersection of a rotation axis and a radiation irradiating axis is low, a small Laminographic angle alpha1 is set. In case a high resolution capability is required in the depth direction, even if the photographing area is narrow, a large Laminographic angle alpha2 is set. Since a balance between the resolution capability in the depth direction of the subject and the photographing area can be adjusted by varying the Laminographic angle, the photographing modes can be freely selected to thereby carry out the tomography suitable for the photographing requirement.
