PROBLEM TO BE SOLVED: To provide a tomograph which controls a dose according not only to an object but also to an incident angle to retain image quality (for example S/N ratio) constant. SOLUTION: In the X-ray tomograph constituted of an X-ray generating means, an X-ray imaging detector for imaging the above X-ray, and a mechanism control means for varying the relationship between the X-ray generating means and the X-ray imaging detector 3, the tube current of the X-ray generating means is controlled according to the incident angle of the X-ray relatively to the X-ray imaging detector 3.
