Abstract
The invention relates to a system (100) for generating and collimating an X-ray beam (104), comprising an X-ray tube insert for generating the X-ray beam, the X-ray tube inert being a vacuum tube; a tube housing (102) for containing the X-ray tube insert (101), the tube housing being made of X-ray absorbing material; a collimator (103) for collimating the X-ray beam (104); wherein the collimator (103) is arranged in between the X-ray tube insert (101) and the tube housing (102). The invention also relates to a corresponding apparatus for scanning an object of interest with an X-ray beam (104) comprising the system.
Claims10
A system for generating and collimating an X-ray beam, comprising:
- an X-ray tube insert for generating said X-ray beam;
- a tube housing for containing said X-ray tube insert, said tube housing being made of an X-ray absorbing material;
- and
- a collimator for collimating said X-ray beam;
- wherein said collimator is arranged between said X-ray tube insert and said tube housing, wherein said collimator comprises a plurality of collimating areas, and wherein said collimator is adapted to be movable with respect to the X-ray tube insert so as to select one of the plurality of collimating areas for collimating the X-ray beam;
- wherein at least one collimating area of the plurality of collimating areas comprises a plurality of binary openings, said binary openings having a higher density in a center region of a collimating area than at border regions of the collimating area.
