摘要： PROBLEM TO BE SOLVED: To provide a technology for improving resolution of an image in X-ray CT imaging.SOLUTION: In a state where an X-ray generator 13 and an X-ray detector 21 for emitting X-ray cone beam BX1 are made opposite to each other, they are rotated by an angle of rotation wherein a fan angle of the X-ray cone beam BX1 is added to 180 degrees to collect projection data, with a center of an imaged area CA (a part of a dental arch) as a rotary center. While rotating, the X-ray generator 13 and the X-ray detector 21 are rotated so that a high scattering region HSR high in degree of X-ray scattering is interposed between the X-ray generator 13 and the imaged area CA. Thus, a deterioration in picture quality of an X-ray image caused by scattering of the X-ray in the high scattering region HSR is suppressed.
