In the exemplary embodiments a layer is to be scanned which is generally parallel to the longitudinal axis of the patient support. For example, a radiation source and a radiation receiver may be rotated in an arc about a rotational axis which lies perpendicular to the longitudinal axis of the patient support to scan a layer area in such a way that the scanned layer within the exposure subject is traversed exclusively along beam paths each of which is crossed along its entire length in the subject by a multitude of other beam paths.

Radiation diagnostic device for generating tomographic images

In an illustrated embodiment, the fan shaped beam of penetrating radiation has a central ray directed offcenter relative to a row of detectors e.g. by a distance corresponding to one-fourth the detector separation. In this way, for each projection with a given central ray angle, further points can be derived by interpolation using the measurements from other projections. With a given number of detector elements, the number of points per projection can be doubled in this way.
