Abstract: In a method for the production of x-ray-optical gratings composed of a first material forming of periodically arranged grating webs and grating openings, a second material is applied by electroplating to fill the grid openings. The electroplating is continued until a cohesive layer of the second material with uniform height is created over the grating webs with this layer having a large absorption coefficient, the absorption properties of the grating structure of the grating are homogenized, so an improvement of the measurement signals that are generated with this grating is improved. Moreover, the mechanical stability of gratings produced in such a manner is improved.

Abstract: A method is disclosed for reconstructing a tomographic representation of an object from projection data off a moving radiation source through this object onto a detector, filtering and back projection of the projection data being executed in the reconstruction. In an embodiment of the method, by using at least one identical spatial arrangement of the radiation source, the detector and a test object instead of the object to be scanned, there is determined by test projections and an iterative reconstruction technique, a filter that in the given arrangement results in an optimum filtering and back projection of the projection data of the test object for the tomographic representation. Further, the object is scanned instead of the test object in the given arrangement and projection data are determined. Finally, the reconstruction of the tomographic representation is carried out using these projection data and the filter determined. Moreover, an embodiment of a tomography unit for carrying out this method is also disclosed.
