A method for recovering a composite - x-ray image data set of two sequences of 2 - d - x-ray image data etching

摘要

A method for recovering a composite - x-ray image data set, in which a first sequence of 2 - d - x-ray image data of etching a region (34) of an object with a first resolution is obtained and a second sequence of 2 - d - x-ray image data etching of a partial region (36) of the object with a higher than the first resolution is obtained, and wherein the composite - x-ray image data set with the use of both sequences is calculated, characterized in that, of a biplanar faceted - system (10) with two independently movable pairs of x-ray source (14, 22) and x-ray detector (16, 24) in each case a pair of (14, 16; 22, 24) for the obtaining a sequence is used, wherein at least a part of the 2 - d - x-ray a result of the same time with a 2 - d - x-ray image data set from the other sequence or between two 2 - d - x-ray image data etching is obtained from the other sequence.
