The invention relates to a method for non-destructively inspecting an object (104), wherein electromagnetic radiation (113, 123, 133) is passed through the object (104) and intensity values of unabsorbed beams are measured and evaluated, the method comprising the following steps: generating a three-dimensional data set (300) in which a first material quantity value corresponding to a first material property of the object (104) is associated in each case with individual spatial elements (301) of the object (104) by means of a computed tomography method; determining an inspection space (310), in the three-dimensional data set (300) representing the object (104), which has spatial elements (301) whose first material quantity value is in a predetermined value range; deriving values, based on the three-dimensional data set (300), which in each case correspond to a spatial geometric quantity of the inspection space (310) in a predetermined projection direction (PR1, PR2); generating a two-dimensional data set (400) in which a second material quantity value corresponding to a second material property of the object (104) is associated in each case with individual surface elements (401) of the object (104), based on a surface projection of the object (104) in the predetermined projection direction (PR1, PR2) by means of a two-dimensional X-ray method; determining an inspection region (410) in the two-dimensional data set (400) by computing a projection (310′) of the inspection space (310) into the two-dimensional data set (400), corresponding to the predetermined projection direction (PR1, PR2); and transferring the derived values of the spatial geometric quantity into corresponding surface elements (401) of the projection (310′).
