IMAGE-BASED DETERMINATION OF COMPRESSION ELEMENT DEFLECTION

摘要

The invention relates to X-ray imaging technology as well as image post-processing and analyzing. An X-ray imaging system element (3), an X-ray imaging system (2), the use of a system element in an X-ray imaging system and the method (40) of determining a deflection of a compression element is disclosed. The X-ray imaging system element (3) comprises two compression elements (8a, 8b), which are movable relative to one another. An object (10) is introducible and compressible between the compression elements. At least one of the compression elements is adapted to alter its geometrical shape and/or alignment relative to the other during compression. At least one partly X-ray opaque marker element (24) is provided on one of the compression elements, which marker element is adapted to allow detection of an alteration of the geometrical shape of the respective compression element (8a, b).
