Abstract
A computer tomography system includes an X-ray tube having an elongate anode across which a beam spot can be displaced, a scanogram being formed by correctly shifting the profiles measured in the various source positions with respect to one another, followed by superposition. Parts of the object which are situated in a selected layer are thus emphasized in an image, parts of the object which are situated outside the selected layer being blurred. When a point of interest in the object is determined by observation of the scanogram, the same apparatus is used to produce a tomography slice image transverse the scanogram image. An important additional advantage consists in that the permissible power to be applied to the X-ray source may be higher. Furthermore, a scanogram thus obtained is not necessarily disturbed by the failure of one or more detectors.
