BRIEF DESCRIPTION OF THE DRAWINGS FIG.

FIG. 1 shows a base 1 supported on the floor of an examination room.
It is shown. The base 1 is connected with link arms 2 and 3 consisting of two parts. These link arms 2, 3 are pivotable about two horizontal axes 4, 5. The base 1 is rotatable about a vertical axis 6. A detector holder 7 of the X-ray imaging apparatus is connected to the free ends of the link arms 2 and 3 so as to be pivotable about another horizontal axis 8. Detector holder 7
Has a flat detector consisting of a matrix of detector elements, the electrical signals of which are sent to an image computer, which forms an image of the examination area of the patient from the signals of the detector elements.

FIG. 2 shows the detector holder 7 located below the patient table 9. Detector holder 7
Since the X-ray radiator 10, which is freely adjustable in three dimensions, is located above the patient table 9, imaging can be performed with a patient lying down. In FIG. 2, the position of the detector holder 7 in which the detector surface is located at the vertical position is further indicated by broken lines. The detector holder 7 is guided by a wall base 11 for taking a chest image of a patient 12.

A space 13 shown by a dashed line is located between these photographing positions of the detector holder 7 shown in FIG. In this space 13, another shooting may be performed in connection with another shooting mechanism.

FIG. 3 shows that the detector holder 7 is supported by a parallelogram link mechanism 14 provided on a support device 15 so that its height can be adjusted, and also that it can be freely adjusted three-dimensionally. It is shown. The support device 15 is guided slidably in the longitudinal direction by a guide 16 on a bottom rail 17 (see FIG. 4). FIG. 4 further shows that the guide 18 is likewise slidably guided on the bottom rail 17. The guide 18 holds the X-ray radiator 10 in a space so as to be adjustable three-dimensionally by a support device 19. The patient table 9 is supported on one side of the X-ray imaging apparatus in FIG. 4 so as to be pivotable about a horizontal axis 20. The detector holder 7 can be tilted about a horizontal axis 8 and also tilted about a horizontal axis 21 extending perpendicular to the horizontal axis 8. Therefore, imaging under a lying patient and an upright patient is possible. The X-ray radiator 10 can be adjusted accordingly.

The patient table 9 is provided with a connecting means 22. This connecting means 22 is compatible with the connecting means 23 provided on the detector holder 7. Thereby, the detector holder 7 can be firmly connected to the patient table 9. In this case, the detector holder 7 moves with the patient table 9 and such movement is automatically adjusted accordingly.

FIG. 4 further shows a detector 24 formed as a flat detector (solid detector consisting of a matrix of detector elements).

In the embodiment shown in FIGS. 5 to 7, a column 25 supported on the floor of the examination room is provided. On this column 25, a detector holder 7 having a detector 24 is supported via a telescopic device 26 so as to be freely adjustable in three dimensions. In FIG. 5, the detector holder 7 is the base 2
7, it is possible to take an image of a patient lying down. FIG. 6 shows the detector holder 7 in such a position that an image can be taken under an upright patient. FIG. 7 shows the detector holder 7 in such a position that an image can be taken from the side of the patient lying on the table 27. In this case, the central radiator extends transversely to the bearing surface of the platform 27.

The X-ray radiator is not shown in FIGS. The X-ray radiator is freely adjustable in three dimensions. The detector holder 7 can likewise be freely adjusted in three dimensions as already described, in particular the telescoping device 26
It is also rotatable via.
