Tomographic apparatus for producing transverse layer images
In an exemplary embodiment, a radiation-measuring arrangement comprises a radiation source which produces a fan-shaped beam of rays, and a radiation receiver which determines the radiation intensity behind the subject. The beam of rays executes a scanning movement in the layer plane for scanning a layer area which is greater than the layer area corresponding to the fanshaped extent of the beam of rays. Furthermore, there is a rotating ring for the measuring arrangement for irradiating the radiography subject from different directions. The output signals of the radiation receiver are transformed by a measured value converter into a layer image. The measuring arrangement is mounted on a rotatable support which is pivotally mounted on the rotating ring and is swivelled by a drive element of a second rotating ring when the angular velocity of the second rotating ring differs from the angular velocity of the first rotating ring.
