Antiscatter grid for reducing a scattered radiation in an x-ray machine, and x-ray machine having an antiscatter grid

摘要

To prevent an imaging of an antiscatter grid particularly effectively, even in the case of dynamic applications, an antiscatter grid is disclosed for an X-ray detector which exhibits an active pixel matrix. The antiscatter grid, in at least one embodiment, includes absorbing laminas, aligned substantially parallel to the direction of an X-radiation, for reducing a scattered radiation in an X-ray machine. The absorbing laminas are movable in a fashion perpendicular to the direction of the X-radiation at a minimum frequency value of 10 Hz, and at a maximum travel value of two pixel sizes of the X-ray detector that can be assigned to the antiscatter grid.
