Abstract
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.
