Problems solved by technology

[0006] The problem with the x-ray device shown there is that the construction of the x-ray device is very cost-intensive, since there the production of the x-ray optical gratings of the required size is very expensive and currently only the size 50 mm x 50 mm can be produced raster
The modular assembly of multiple such gratings also hides big problems

Embodiment Construction

[0030] exist figure 1 In a first variant, a mammography system 1 is schematically shown, in which a light cone 10 is generated by means of a focal point 7 on an x-ray tube (not shown in further detail), which is directed toward the electronic planar detector 2 . The planar detector 2 has a plurality of detector elements 2.1 which are arranged in a plane such that each detector element 2.1 generates a pixel of the x-ray image for image reconstruction. Arranged on the x-ray tube in the beam path behind the focal point 7 is a grating attachment 8 with an absorption grating G0 that generates a plurality of very narrow x-ray sources by means of a plurality of grating webs or grating laminae arranged in parallel and The coherence condition for the interferometric check is thus fulfilled. The breast 6 of the examination subject, ie a female patient, is situated between the two compression plates 4 and 5 , as is customary in mammographic x-ray recordings. A region 9 of particular inte...

Abstract

An X-ray device and a supplementary system are provided for interferometric X-ray imaging of a patient on the X-ray device in order to generate projective absorption recordings. An emitter-detector system includes a focus-forming X-ray tube and a digital flat-panel detector having a multiplicity of pixel-generating detector elements. A computer system has a program memory. A mobile grating attachment includes a first interferometric X-ray grating, a second interferometric X-ray grating disposed at a distance from the first X-ray grating in the radiation direction, and a displacement device for displacing the second X-ray grating in the plane of the second X-ray grating in steps over at least one detector element.

Description

technical field [0001] The invention relates to a supplementary system for the interferometric X-ray imaging of a patient on an X-ray device for producing absorption imaging of projections, which X-ray device has an X-ray tube forming a focal point and a An emitter-detector system consisting of a digital planar detector of a plurality of detection elements generating pixels and an arithmetic system with a program memory. Furthermore, the invention also relates to an x-ray device for absorption imaging, which produces projections with an emitter-detector system, which has the aforementioned supplementary system. Background technique [0002] Interferometric X-ray imaging is based on introducing one, two or more gratings into an X-ray imaging system. Typically, gratings are named G0, G1, and G2 according to their order in the optical path. The absorption grating G0 is close to the x-ray source and also ensures that the coherence conditions necessary for imaging are observed ...
