Abstract: A method, device, and computer program product for capturing projection images of an object are provided. An x-ray beam source is moved by a control unit on a path into a plurality of positions, in which an x-ray beam is transmitted. An x-ray beam detector is moved by the control unit into a plurality of positions, in which the x-ray beam, penetrating the object, is detected. The x-ray beam source and/or the x-ray beam detector are moved on a calculated path around the object, at a constant distance between the x-ray beam source and the x-ray beam detector or the object. The path is described by an nth degree polynomial and determined by the control unit through an optimization of a path along the central x-ray beam. The polynomial is selected such that a safety clearance with respect to the object is maintained and a distance between the x-ray beam detector and the object is minimized.

Abstract: The present invention relates to an X-ray system and method for generating 3D image data. The X-ray system comprises a radiation detector, a movable X-ray tube assembly and a control unit, wherein in a working state of the system the radiation detector is detachably positioned in a spatially fixed manner and the X-ray tube assembly can be moved into relative positions relative to the radiation detector. Projection images recorded in the relative positions can be processed together with the coordinates of the relative positions using an iterative reconstruction technique or other image processing methods so as to obtain 3D X-ray images. The X-ray tube assembly is attached to a motor-driven movable stand arm and can be displaced using a control unit. The stand base of the movable stand can be positioned in a spatially fixed manner, so that it has a defined fixed position relative to the radiation detector.

Abstract: The invention relates to a method and a device for generating a three-dimensional image of an object, said device comprising a movable radiation source, a radiation detector, and an analyzing unit. The radiation source is moved relative to the object to be imaged into multiple positions in a first movement on a first track 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 and the radiation detector carry out a second movement relative to the object to be imaged on a second track which is at least partly different from the first track at the same time as the first movement 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.

Abstract: The invention relates to a method for producing a sectional image of an object consisting of artifacts, wherein two-dimensional image data is, for example, produced with the aid of a computer tomograph. Two-dimensional image data is produced from various projection devices. According to the invention, pixels, which have a disruptive data value caused by the artifact, are detected. The thus defected pixels are combined to form image areas. In a next step, the image areas are filled by means of filling methods and corrected image data is thus produced. The cross-sectional image of the object is produced on the basis of the corrected image data by retroprojection, for example.
