Abstract: The invention relates to a method for generating 3D tomographic images of an object (4), according to which a radiation source (1), in particular an X-ray source is displaced in relation to the object (4). The radiation source (1) emits a conical beam of radiation (2) that strikes the object (4), the radiation that has passed through the object (1) and has been weakened in intensity is captured by a detector (5); which is located in, he conical beam (2) behind the object (4) in relation to the radiation source (1). The radiation source (1) and the detector (5) are combined in a source-detector assembly (7), which is rotated about a rotational axis (6) during the generation of images in the reference system that is defined by the object (4). Said rotational axis (6) is modified during the generation of the images and/or the source (1) and/or the detector (5) in the reference system that is defined by the source-detector assembly (7) is/are displaced during the generation of the images.

Abstract: The invention relates to a method for producing 3D tomographic images of an object, whereby a radiation source (1), especially an X-ray source, is moved in relation to the object in a plane of motion (6) about a rotating center. The radiation source (1) emits radiation in a radiation cone (2) whose center beam (3) impinges the object. A correspondingly entrained detector (4) is arranged in said center beam, on the side of the object facing away from the radiation source, and is impinged upon by the radiation attenuated in its intensity by the object. The movement is carried out in such a manner that the center beam (3) is tilted by an angle in relation to the plane of motion (6).

Abstract: A method for presenting image data 1 that represents a three-dimensional object 7 in a space, wherein projection data which represents a two-dimensional projection 6 of the object 7 are generated by computational superimposing of multiple image planes, wherein the projection 6 is displayed on a monitor for viewing by a user, wherein a sub-area 8 is selected from the projection 6, wherein a detail image 9 is generated inside the sub-area 8 with direct or indirect recourse to the image data 1, wherein the detail image 9 has different informational content than the projection 6, and wherein the detail image 9 is presented on the monitor within the sub-area 8.

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.
