An objective of the present invention is to provide a high spatial resolution CT image or a CPR image with no deterioration due to interpolation by photographing a site of interest of a subject while constantly moving the site of interest of the subject toward the center of photography. When photographing while rotating a rotating disk wherein a radiation source and a radiation detector are positioned in opposition to each other and while moving a subject in a body axis direction of the subject which is a direction which intersects the rotation direction, either a platform whereupon the subject is mounted is moved in a direction which is orthogonal to the body axis direction of the subject or an angle of a scanner is changed. In image reconstruction, the image reconstruction is carried out using either movement information of the platform during photography (movement information in the direction which is orthogonal to the body axis direction) or the angle information of the scanner. |
