Abstract

An x-ray apparatus includes an x-ray tube having a focus, the x-ray tube being contained in a housing and the housing having a mechanical distance-measuring device attache thereto. The mechanical distance-measuring device is suitable for obtaining a measured value which exactly corresponds to the focus-to-skin distance for all types of examinations. The mechanical distance-measuring device, which may be a tape measure, is connected to an electrical signal generator which converts the mechanically measured value into a corresponding electrical signal.
