    摘要： 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.

    摘要： The present invention relates to a method and a device for capturing projection images of an object to be replicated (7). The device comprises a beam source (2), a beam detector (1) and a control unit (3), wherein the beam source (2) is moved by the control unit (3) on a path (12, 18, 27) into a plurality of positions, in which a beam emitted by the beam source (2) is transmitted in a cone beam shape around a central beam. At the same time as the beam source (2) is moved, the beam detector (1) is moved by the control unit (3) into a plurality of positions, in which the beam emitted by the beam source (2) and penetrating the object (7) to be replicated is intercepted to capture a projection image. The beam source (2) and/or the beam detector (1) are moved on a calculated path (13, 18, 20, 27) around the object (7) to be replicated, at a constant distance between the beam source (2) and the beam detector (1) or the object (7) to be replicated, which path is described by a polynomial nth degree and determined by the control unit (3) through an optimisation of a specified path along the central beam (19, 20), wherein the respective polynomial is selected in such a manner that a safety clearance with respect to the object (7) to be replicated is maintained and, at the same time, a distance between the beam detector (2) and the object (7) to be replicated is minimised. The invention further relates to a computer program product with a command sequence for actuating the device and performing the method.

    摘要： The present invention relates to an X-ray source (2) for irradiating an object (8) to be imaged with X-ray radiation, wherein the X-ray source (2) is moveable into a plurality of defined recording positions relative to the object (8) to be imaged. A module (4, 5, 13) is arranged directly on the X-ray source, said module being designed to project a marking onto the object (8) to be imaged and/or to check a position of the object (8) to be imaged and/or of the marking, wherein the module for checking the position of the object (8) to be imaged and/or of the marking comprises a detector (5) for optical radiation. In addition, the present invention relates to an X-ray device (6) comprising the X-ray source (2) and a method for using the X-ray device (6).
