Abstract
In a method and x-ray apparatus for making and reproducing a radiological tomogram of a subject, the subject is irradiated with radiation emanating from a focus disposed at a known distance from a focal plane, situated at the subject. The focal plane is disposed at a known distance from a radiation receiver, which is disposed in the image plane, and which contains a number of picture elements. In a digital radiological tomogram, either the slice position with the aforementioned distances is allocated to respective picture elements, or a correction factor, based on the slice position and the aforementioned distances, is allocated to the respective picture elements, from which a corrected image is obtained with the subject appearing with a corrected size corresponding to the size of the subject in the focal plane.
