Abstract: A beam collimator arrangement for scanned-slot x-ray imaging having one or several collimators in an x-ray apparatus is disclosed. The beam collimator arrangement includes an x-ray source; an x-ray image receiver positioned to receive x-rays from the x-ray source; a compressor or means for compressing a female breast to be examined where the compressor is positionable between the x-ray source and the x-ray image receiver; and the beam collimator is positioned between the x-ray source and the compressor. The beam collimator arrangement is arranged on a carrying structure to displace the beam collimator arrangement between a first position when no x-ray exposure is conducted and a second position before x-ray exposure is initiated.

Abstract: The invention relates to a grid holder for an X-ray diagnostic system. The grid holder cooperates with a flexible X-ray grid, which in a flat state has a first focus distance/convergence distance of about 120 cm. A flexing means, preferably in the form of an inflatable element, which can exert a pressure on the surface of the grid, is arranged to flex the grid in a first direction to a first position in which it has a second convergence distance of about 180 cm. Another corresponding flexing means is arranged to flex the grid in the opposite direction to a second position in which it has a third convergence distance of about 80 cm. This allows variable convergence distances with minimum flexing of the grid. The invention also relates to grid devices with grid holders and grids as well as X-ray diagnostic systems comprising such grid holders/grid devices.
