Patent ID: 7127038

Claim:
A grid holding device for a medical X-ray diagnostic system, which device is adapted to cooperate with a flexible, plate-shaped X-ray grid ( 401 ), which in a flat state has a first convergence distance, and which device comprises a flexing means for flexing the X-ray grid in order to adjust the convergence distance of the X-ray grid, wherein the flexing means comprises a first means ( 404 ) for flexing the X-ray grid in a first direction from the flat state to a first predetermined flexed position, in which the grid has a second convergence distance, which is longer than the first convergence distance, and a second means ( 404 ′) for flexing the X-ray grid in a second direction from the flat state to a second predetermined flexed position, in which the grid has a third convergence distance, which is shorter than the first convergence distance.
