Systems include an x-ray optical arrangement that includes an x-ray source configured to emit an x-ray beam along a beam path and through an object placement location situated to receive an object for inspection, an object grating situated along the beam path, and a detector situated along the beam path to receive the x-ray beam after propagating through the object grating and object placement location and to detect image data, wherein the object grating includes object grating elements arranged in an object grating pattern; and a movement stage providing a plurality of computed tomography imaging positions for the object by the x-ray optical arrangement; wherein the object grating pattern and a positioning of the x-ray source, object grating, and detector in relation to each other are configured to provide a plurality of computed tomography detection modes in the image data.
