Section: description

In the figures, identical elements are identified with the same reference characters. An exemplary embodiment of an x-ray diagnostic device in conformity with the invention is shown in FIGS. 1 and 2. The inventive x-ray diagnostic device has a positioning plate 1 for an examination subject as well as a radiation receiver 2 that are mounted at a base 3. The radiation receiver 2 is a solid state detector and is mounted at a gallows frame 4 so as to be adjustable with respect to the positioning plate 1. The radiation receiver 2 can, as proceeds from FIG. 2, be mounted for this purpose at a first end of a first gallows frame arm 5 oriented substantially horizontally, so as to be adjustable around the orthogonal axes x, y and z. In order to further increase the adjustability of the radiation receiver 2, the first gallows frame arm 5 can be mounted to be adjustable along its longitudinal axis and along a longitudinal axis of a second gallows frame arm 6 oriented substantially vertically to the first arm 5. Via the first gallows frame arm 5, the radiation receiver 2 is thus adjustable in a direction essentially vertical to the longitudinal axis 7 of the positioning plate 2. The distance between the radiation receiver 2 and the positioning plate 1 can be set by adjustment along the second gallows frame arm 6. The magnification scale also can be changed, for example, when a radiation emitter 8 is arranged below the positioning plate 1. It further proceeds from FIGS. 1 and 2 that the positioning plate 1 and/or the radiation receiver 2 are mounted via the gallows frame 4 at a holder 9 at the base 3. Swivelling around a rotational axis 10 can be effected via the holder 9. In addition, it is possible to adjust the holder 9, and thus the positioning plate 1 and the radiation receiver 2 in a vertical direction via a lifting means that is arranged at the base 3 which engages the holder 9. In the scope of the invention, the positioning plate 1 can be seated to be adjustable not only along its longitudinal axis 7, but also along its transverse axis. In FIG. 1 it can be seen that the gallows frame 4 can be adjustably seated at guides along the positioning plate 3 at the holder 9. Figure shows 3 that the radiation receiver 2 can be adjusted in a vertical position by means of swivelling around the x-axis with respect to the surface to the positioning plate 1, so that an examination subject can also be irradiated from the side using a separate radiation emitter for the preparation of an x-ray exposure. FIG. 4 shows how a height adjustment of the positioning plate 1 with respect to the holder 9 allows the radiation receiver 2 to be brought into a position below the positioning plate 1 by rotation around the x-axis and adjustment along the first and second gallows frame arms 5 and 6. An x-ray exposure also can be prepared using a separate radiation emitter, with the separate radiation emitter arranged above the positioning plate 1 and above the examination subject. Such a height adjustment of the positioning plate 1 is, however, only required if not enough room is provided for the radiation receiver 2 below the positioning plate 1. The positioning plate 1 can be brought into a vertical position by means of swivelling and raising the holder 9, wherein so-called wall exposures, i.e. examinations of a standing patient can be performed. Furthermore, it is possible to bring the examination subject into a head exposure position by swivelling in an opposite direction, in order to allow specific x-ray exposures to be prepared. By means of the invention, an x-ray diagnostic device is achieved that allows good accessibility and versatile applicability with a compact structure. Although modifications and changes may be suggested by those skilled in the art, it is the intention of the inventors to embody within the patent warranted hereon all changes and modifications as reasonably and properly come within the scope of their contribution to the art.
