Embodiment Construction

[0053] exist figure 1 A roentgen ray device 100 is schematically shown in . The roentgen ray device 100 comprises a roentgen ray tube 101 arranged to generate a roentgen ray beam. Furthermore, the roentgen ray device 100 comprises a roentgen ray detector 102 which is provided for detecting a roentgen ray beam. It is possible for the examination object to be arranged between the roentgen ray tube 101 and the roentgen ray detector 102 such that one or more roentgen ray images can be detected by the examination object by means of the roentgen ray beam. The roentgen ray tube 101 and the roentgen ray detector 102 can be adjusted separately from each other, ie can be rotated and positioned. The orientation and positioning of the roentgen ray tube 101 together define the pose of the roentgen ray tube 101 . The pose determines the viewing angle of the corresponding roentgen ray image.

[0054] Furthermore, the X-ray device 100 includes a control unit 150 which is provided for cont...

Abstract

A first X-ray image is taken in a predefined position of a focal point (120) and in a first orientation of an X-ray tube (101) of an X-ray appliance (100). The X-ray tube (101) is then adjusted by rotation about a predefined angle and by positioning, wherein the focal point (120) is located in the predefined position prior to the adjustment and after the adjustment. After the adjustment, the X-ray tube (101) is located in a second orientation. A second X-ray image (202) is then taken in the predefined position and in the second orientation. A combined X-ray image composed at least of the first and second X-ray image is established.

Description

technical field [0001] The invention relates to a method for imaging with a roentgen ray device and a roentgen ray device. In particular, the present invention relates to different techniques in which a first and a second roentgen ray image are detected with a predetermined position of the focal point and with different orientations of the roentgen ray tube of the roentgen ray device and a combined roentgen ray image is thereby generated. Roentgen ray image. Background technique [0002] Techniques are known for imaging with roentgen ray equipment. In this case, a roentgen ray beam, ie in the wavelength range of approximately 10 -3 Electromagnetic radiation in the range of nm to about 10 nm. After passing through the examination object, the roentgen ray beam can be measured by means of a roentgen ray detector of the roentgen ray device and used for imaging. [0003] Roentgen ray devices usually have a so-called cone-beam geometry of the roentgen ray beam: in such cases t...
