The invention relates to a method and a device for generating a three-dimensional image of an object (14), said device comprising a movable radiation source (1), a radiation detector (2), and an analyzing unit. The radiation source (1) is moved relative to the object (14) to be imaged into multiple positions in a first movement (11) on a first track (3) which lies on a first plane in order to capture images, at least one image being captured in each said position. The three-dimensional image is reconstructed from the captured images by the analyzing unit. The radiation source (1) and the radiation detector (2) carry out a second movement (6) relative to the object (14) to be imaged on a second track which is at least partly different from the first track (3) at the same time as the first movement (11) in order to reduce artifacts in the image, said artifacts being generated due to radiation absorption. In the process, the first movement and the second movement are superimposed.

The present invention relates to an X-ray system and a corresponding method for generating 3D image data. The X-ray system comprises a radiation detector, a moveable X-ray emitter and a control unit, wherein the radiation detector is detachably positioned fixed in space in a work state of the system and the X-ray emitter can be moved into relative positions relative to the radiation detector. Projection images recorded in the relative positions, in combination with the coordinates of the relative position, can be processed to form 3D X-ray images by means of an iterative reconstruction technique or other image processing methods. The X-ray emitter is attached to a stand arm that is moveable in a motor-driven fashion and can be displaced by a control unit. The foot of the stand of the moveable stand can be positioned fixed in space by fixation devices such that it has a defined fixed position with respect to the radiation detector.

The invention relates to a method for manufacturing a compact component (10) comprising a shell (12), optionally a grid structure (14) that is situated inside the shell (12) and consists of a shell material, and a core structure (16) that fills the interior of the shell (12) and consists of a core material. The method comprises the following steps: (a) generative construction of at least one layer of the shell (12) that runs along a sectional plane of the component (10) and optionally at least one layer of the grid structure (14) consisting of a particulate material (18) of the shell material or at least of a reagent of the same by means of a beam melting method; and (b) melting, sintering and/or solidification of a nanoparticulate material (20) of the core material, which is situated in the interior of the at least one layer of the shell (12) or of at least one reagent of the same, for forming the core structure (14) of the component (10). The invention further relates to a corresponding compact component that can be produced by means of the method.
