When reconstructing the absorption values at picture elements of a plane under examination from measured values which were measured by means of a scanner for transverse tomography, it is necessary to assign at least one intermediate value to each picture element from each measured series. In general said intermediate value must be computed from up to three measured values and weight factors. The invention describes a computation method in which the intermediate values which are assigned to the various picture elements are not computed accurately for the various picture elements but only to an approximation by interpolation. Computing time is, thus, substantially reduced with only a small increase in error. |
