<p>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 the 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.</p> |
