ABSTRACT:
An alignment method and system for aligning an anti-scatter grid with an x-ray source of a radiographic apparatus, to facilitate accurate alignment of the central x-ray beam of the x-ray source of the radiographic apparatus with a focused grid. The present invention uses a first light projector that is substantially fixed relative to the x-ray source, which produces a first alignment image that is substantially fixed relative to the grid. Also included is a second light projector that is substantially fixed relative to the grid, and that produces a second alignment image that is substantially fixed relative to the x-ray source. The first light projector is preferably the collimator light included within the collimator housing of the x-ray apparatus, and the second light projector is preferably a laser light source, that is attachable to a grid cassette holding the grid.
