Abstract: X-ray apparatus provided with an excessive-size indication which gives a signal to the radiologist when the cross-sectional area of the beam used for fluoroscopic examination exceeds the size of the radiograph to be made.

Abstract: The device has an X-ray source (2), an aperture unit (4) with aperture plates (41) to form an X-ray beam (210) and a light source (42) to form a light beam through the aperture, using a mirror arrangement (43). Correction apertures (44) are provided, which are transparent to X-rays but opaque to light, to limit the light beam. An Independent claim is included for an aperture unit for an X-ray source.

Abstract: The X-ray diagnostic device has an X-ray source; an image generator; an aperture system, which limits the width of the beams (100,200) from one or other of two sources (1,2); and a control system which operates a motor-drive which adjusts the position of the shutters (6), where the novelty is that the control system ensures that the shutters (6) take up a first position (h1), with the X-ray beam (101) and a second position (h2) with the second X-ray bundle (200), such that, in the plane of the image generator (9), the fields of the two sources (1,2) have, approximately the same height (H).
