Abstract

PROBLEM TO BE SOLVED: To provide a radiograph which enables radiography of objects at various positions using only one system. SOLUTION: The apparatus is equipped with a truck 1 to which applied a telescope 3 in the manner that a detector holder 2 put on its upper end is able to turn 90 degree and height adjustable. The detector holder 2 is to hold a plane detector 4 in the manner it can optionally move it to either vertical or horizontal position. Further equipped is an X-ray beam generator 7 which can be adjusted to optionally execute X-ray radiography object body either lying, sitting or standing by means of the X-ray beam generator 7 and the plane detector 4 using a ceiling suspension frame 8.

2. Description of the Prior Art It is known to perform X-ray imaging of standing and lying specimens by means of different imaging systems connected to a single X-ray beam generator. For X-ray imaging of a standing sample, a wall-mounted stand is known. On the other hand, X-ray imaging of a lying sample is performed using a sample bed, and an imaging system is provided below the sample bed. The X-ray beam generator is then arranged in such a way that it can be adjusted to the respective imaging system applied.

[0003] US Patent No. 4,948,855 describes an X-ray diagnostic system. In this X-ray diagnostic system, an X-ray beam generator, a sample bed, and an X-ray image amplifier as a beam detector are suspended on a robot arm. Therefore, the X-ray beam generator, the sample bed, and the X-ray image amplifier can be individually adjusted using a computer. This known system is configured for testing on a lying specimen.

From page 08 to page 110, page 112, page 114,
On page 116, a planar detector for X-ray imaging is described. The configuration of an X-ray imaging apparatus having such a flat detector cannot be read from this document. Finally, U.S. Pat. No. 5,048,070 describes an X-ray imaging system having an X-ray beam generator and two specimen mounting devices. This X-ray imaging system is an apparatus for performing X-ray imaging of a lying sample and a standing sample. These two sample mounting apparatuses are assigned to individual X-ray imaging apparatuses.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an X-ray imaging apparatus in which a single imaging system can be used to image a sample at various positions.

[0005]

According to the present invention, there is provided, in accordance with the present invention, a gantry, on which a telescope is provided, at the upper end of which the height of a detector support is adjusted. And is arranged to be rotatable by 90 °, the detector support being adapted to selectively move a planar detector comprising a matrix of detector elements to a vertical or horizontal position. And an X-ray beam generator, the X-ray beam generator using a ceiling-suspended pedestal, also configured as a telescope, the X-ray beam generator and the X-ray beam generator. The present invention is achieved by configuring an X-ray imaging apparatus that is adjustable so that X-ray imaging of a lying sample, a sitting sample, and a standing sample can be selectively performed by the planar detector.

DESCRIPTION OF THE PREFERRED EMBODIMENTS In an X-ray imaging apparatus according to the invention, the planar detector is advantageously provided with a matrix of detector elements based on aSi. The planar detector is arranged rotatably and adjustably, optionally for imaging on a standing specimen, for example a chest, and also for imaging on a sitting specimen and on a lying specimen. Is also configured to be usable. In this case, the planar detector is arranged below the sample bed in the case of imaging with a lying sample. If the imaging system is arranged sideways, the specimen can be placed sideways on this bed.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in more detail hereinafter with reference to an embodiment shown in the drawings.

The X-ray imaging apparatus shown in the drawings has a detector support 2 on a gantry 1 movable on a floor.
This detector support is arranged rotatable by 90 ° on the telescope 3. Oblique perspective (Schraegdurchst
rahrungen) is also possible. On the detector support 2, a flat detector 4 is supported in a recess. The planar detector is formed from a matrix of detector elements, in particular a matrix of amorphous silicon hydride-based detector elements. The planar detector 4 is connected to a signal processing device 5. This signal processing device forms an X-ray image from the detection signal. This X-ray image is reproduced on the monitor 6. The X-ray beam generator 7 is rotatably suspended on a ceiling suspension stand 8. This ceiling-mounted mount is likewise configured as a telescope.

An image of a standing sample can be taken depending on the positions of the detector support 2 and the X-ray beam generator 7 shown in FIG. For imaging with a lying sample, the sample is placed on the sample bed 9 shown in FIG.
The telescope 3 is reduced by the following width corresponding to the example of FIG. That is, the detector support 2 having the flat detector 4 and rotated by 90 ° with respect to the example of FIG. 1 is reduced to a width that can be arranged below the sample bed 9. X
The line beam generator 7 is also rotated by 90 °.

The imaging of a sitting sample is performed in the example shown in FIG. 1, that is, at the positions of the components 2, 3, 4, and 7 when the telescope 3 is appropriately reduced, and also in FIG. It can also be performed at the position of these components in the example described, for example in the case of thigh imaging. In that case, the sample sits on the sample bed 9 or a suitable chair.
