Section: summary

FIELD OF THE INVENTION The present invention relates to an X-ray diagnostic apparatus for X-ray exposures, having preset X-ray tube voltage and current values, and a preset exposure time and, more particularly, to an apparatus of this type which includes a plurality of filters in conformance with an exposure program for the X-radiation adapted to be selectively employed in coordination with a particular exposure object. DISCUSSION OF THE PRIOR ART An X-ray diagnostic apparatus of this type, for example, it utilized in the formation of dental exposures. In order to provide coordination with the particular object which is to be filmed, it is known to employ a timing switch or an mAs-relay. It is also known that operating keys may be used for the control of the mAs-relay, which are associated with the individual teeth. Prior to the completion of an exposure the key associated with a particular tooth which is to be X-rayed, must be depressed for effecting selection of the corresponding mAs-product. The determination of the mAs-product is carried out by means of an electronic switching installation which is influenced by the operating key. The electronic components are located in a panel which is associated with a single housing-like constructed X-ray diagnostic apparatus, and which also supports the exposure triggering mechanism. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an X-ray diagnostic apparatus of the above-described type having a construction which, in comparison with the state of the technology, is essentially greatly simplified and considerably less expensive. In particular, there is thus obviated the need for a special control panel for the setting of the exposure data. The foregoing object is inventively attained through the provision of an X-ray diagnostic apparatus for X-ray exposures having fixedly set values for the X-ray tube voltage and current, and the exposure time and wherein for a particular exposure program a plurality of filters are provided for the X-radiation in coordination with a particular exposure object and in which a support arrangement is provided for the filters, through the intermediary of which a filter may be selectively interposed into the path of the X-radiation. Thus, pursuant to the inventive object, the coordination of the filter and the particular object which is to be exposed is carried out by interposing the particularly required filter into the path of the X-radiation. The arrangement which supports the filters may be directly positioned on the housing which contains the X-ray tubes. The inventive X-ray diagnostic apparatus is particularly adapted to the completion of dental exposures, in which the X-ray tubes and the high-voltage generator are located in an oil-filled housing, and the support arrangement for the filters is located intermediate an X-ray outlet aperture and a tube which focuses the X-radiation.
