An X-ray diagnostic installation which includes an automatic exposure timer. An X-ray diagnostic installation of the above type is so constructed whereby the setting or positioning of the measuring probe is substantially simplified in contrast with the state of the technology. Located in the housing of the primary ray focusing diaphragm, is an adjustable marking installation which is optically reproducible on the patient, for the imaging or reproduction of a measuring area, and in which there is located on the exterior of the shutter housing at least one scale for reading off its positioning, and wherein the measuring probe is connected with setting means which project out of the cassette drawer, having associated therewith at least one scale for reading off the position of the measuring probe. The user may, in the inventive X-ray diagnostic installation, read off the coordinates of the selected measuring area on the diaphragm housing of the X-ray generator and utilize these coordinates for the setting or positioning of the measuring probe.
