| 摘要 |
An embodiment of the present invention discloses a method for producing projective and tomographic images using X-rays, allowing structures of similar composition to be imaged particularly well by combined evaluation of the behaviour of the test object with respect to the phase displacement during passage of the X-rays and its absorption. At least one embodiment of the invention also relates to an X-ray system and a CT system with respective source grids, phase grids, and analytical grids for carrying out the method.
