ABSTRACT:
An X-ray diagnostic device has an X-ray tube and a diaphragm housing in which diaphragm plates for limiting an X-ray field are contained, as are a lamp and a mirror. The lamp and mirror are configured so that, when the lamp is on, the light therefrom is reflected by the mirror so that the reflected ray field coincides with the hypothetical X-ray field. At least one filter for filtering the X-rays is disposed in the diaphragm housing. The mirror and the filter or filters are attached to a single disk that rotates around an axis such that either the mirror or a filter is within the hypothetical X-ray field.
