A diagnostic X-ray system has an X-ray source that generates an X-ray conical beam, and a panel detector, which has numerous X-ray detection elements arrayed two-dimensionally, opposed to each other so that they can be rotated about the body axis of a subject. CT images of the subject are reconstructed based on projection data acquired by scanning the subject. The panel detector can be offset so that the center of the detecting surface of the panel detector extending in a direction perpendicular to the body axis can be displaced in a direction substantially perpendicular to a reference plane defined with an extension of a straight line linking the focal point of X-rays and a point on the body axis of the subject and with the body axis of the subject.
