A method of forming tomographic images in cross-sectional tomography, in which a body is irradiated by a flat X-ray beam at different angles for successively forming a plurality of profiles on an X-ray screen or an X-ray detector, and a tomogram is constructed from the profiles, wherein the body and the X-ray detector are kept stationary and that, for forming the different profiles, the source of the flat X-ray beam is moved in a relatively short path extending on the side of the body remote from the X-ray detector.
