Description

It is known to produce X-ray images of an object using a computer tomograph and/or other X-ray imaging devices. Each imaging system forms an individual unit, so that a large number of components are required to produce X-ray images.

The invention is based on the object of designing an X-ray examination system with a computer tomograph and other X-ray recording devices in such a way that it is optimized in terms of costs and effort in comparison to the state of the art.

This object is achieved according to the invention by the features of patent claim 1. In the X-ray examination system according to the invention, components for producing different X-ray images are used together, so that the effort is reduced compared to the prior art. For example, a conventional X-ray table with which conventional X-ray images can be produced can also be used to position the patient in a computer tomograph.

The invention is explained in more detail below with reference to an embodiment shown in the drawing.

0 The drawing shows a computer tomograph 1 with an X-ray emitter 9 and a detector 10. The X-ray emitter 9 emits a fan-shaped X-ray beam 11, whose fan plane runs perpendicular to the plane of the drawing, and which strikes the detector 10 formed by a row of detector elements. It is rotated around an object on a table 2 to examine it. A computer 3

GR 95 G 3804

calculates an image of the object from the detector output signals, which is displayed on a monitor 12.

The table 2 can also be used to take conventional X-ray images. For this purpose, it has a cassette holder 5 for interchangeable cassettes. A movably arranged X-ray irradiator 4 enables X-ray images to be taken on these interchangeable cassettes.

For taking pictures of a standing patient, a cassette holder 6 that can be adjusted vertically is arranged on a tripod. The X-ray tube 4 is adjusted accordingly for pictures using the cassette holder 6.

To take pictures using the X-ray 4 and the cassette holder 5 or 6, the recording unit 9, 10 is brought into a starting position and the computer tomograph 1 is moved into a parking position on the wall 14. Here, its X-ray generator 16 is coupled to a wall adapter 7 via a coupling 15 and feeds the X-ray emitter 4.

via a cable 8. The operation can be carried out from the console of the computer 3. The object is stored on the table 2 and the film cassette is inserted into the cassette holder 5. If necessary, the table 2 can be tilted. 25

The following types of images are possible with the X-ray examination system shown:

1. CT images, possibly also spiral CT 2. Digital radiography in shadow image mode 3. Standard X-ray images with film cassette

The main advantage of the system is the shared use of the X-ray generator 16 in the computer tomograph 1, the table 2 and the control unit on the computer 3 for the three recording systems 1; 4,5; 4, 6.

Claims (4)
