PROBLEM TO BE SOLVED: To detect straight lines from the cross-sectional conversion images of coronal images and sagittal images, etc., to remove the straight lines and to remove a ring from axial images especially in a cone beam CT device relating to a radiographic device for using radiation in general and imaging a radiation characteristic distribution inside a testee body such as an X-ray CT device for radiographing images by utilizing the radiation such as X-rays for instance. SOLUTION: An image processor is composed of a two-dimensional X-ray detector means, a means for performing three-dimensional reconstitution from detection data, a means for preparing the cross-sectional conversion images from three-dimensionally reconstituted images, a means for detecting the straight line from the cross-sectional conversion images, and a means for subtracting the detected straight line from the cross-sectional conversion images.
